The need for a meeting stile means there will always be relatively more sound leakage through pair assemblies than with single doors. Properly fitted STC 52 or higher acoustical doors, ZERO's SOUND TRAP-PAIRS system for metal doors achieves an office-friendly STC rating of 41 with an optimal configuration #770 that balances those limitations with appropriate, cost-effective technology. #119WB .916"(23.3) ZBB 961 | WWW.ZEROINT ERNATIONAL #8880 - Visi (14.3) (24.5) .500"(12.7) #40 Trapped Air #362 WWW.

At the end of each feature or department, a light blue back to toc will take the reader back to the table of contents of the issue. • The Internet supplement contains additional information that will be of interest to readers of NNI. This includes: • The current issue of NNI available for free download • NNI archives in PDF format beginning in 1993 • A searchable PDF of annual index pages • A PDF of the current NNI conference calendar and a link to conference calendars for worldwide meetings • Links to I-INCE technical activities and I-INCE Technical Reports President’s Column INCE/USA Announces Collaboration with the Drohan Management Group I am very happy to inform you that as of November 1, 2014 the Drohan Management Group will have taken over the responsibility for running the INCE/USA Business Office (IBO). The IBO is often the main point of contact between the Institute and its members and handles most of our day-to-day operations. If you phone INCE/USA, the call will be answered by the IBO. The IBO is also called on to provide professional guidance to the INCE/USA volunteers. Though the INCE/USA leadership is obviously very familiar with technical engineering issues, we sometimes need advice from people who are experts in the mechanics of running a nonprofit organization. We may seek advice on topics ranging from database management to tax and legal issues. The Drohan Management Group was chosen after a six-month search. This search began with the drafting of a scope of services. This scope is an important document because it defines our needs and how we wish to run the Institute. There was quite a bit of discussion and soul searching that went into developing this document. That scope was included with a request for proposal and was circulated among association management companies. We received over 30 proposals in response to our request. After careful review of all the proposals, many conference calls, and an in-person interview, the INCE/USA search committee unanimously selected the Drohan Management Group (DMG) and recommended them to the Board of Directors. The Board of Directors voted to extend a contract to DMG at our recent meeting at NOISE-CON 2014 in Fort Lauderdale. The Drohan Management Group is principally located in Reston, Virginia, and has been serving nonprofit organizations for 28 years. They are a 2014 September www.inceusa.org large organization with over 50 people serving 20 clients. They have extensive expertise in many areas including finance, communications, information management, meetings and exhibits, creative services, and, of course, general association management functions. Cathy Vail is director of operations at DGM, and she will be our main contact. We are very excited to have DMG on board and look forward to their helping us become more efficient at serving the INCE/USA membership. Though much of their work will occur behind the scenes, their activities will be felt by our membership on many levels. They will be updating our website, improving our online member database, improving our membership response, and helping us identify those areas where we can better serve the membership. We will also rely on them to assist with the many practical aspects of running our conferences—from negotiating with hotels and AV companies to printing the program to running the registration booth. Gordon Ebbitt President INCE/USA [email protected] Though Drohan Management Group will be handling our operations, Joe Cuschieri will continue as our executive director. This arrangement will allow INCE/USA to have a more direct influence on how our daily operations are handled, and it will ensure that the best interests of our members are understood and served. With the assistance of DMG, however, Joe can begin to shift his attention from day-to-day issues to longer range strategic planning. Please join me in welcoming Cathy Vail and the entire team from the Drohan Management Group to INCE/USA. I am looking forward to a long and productive relationship.

Cert. nnieditor@ noisenewsinternational.net What value do INCE-USA and I-INCE provide to our members, and how will this evolve? I have been thinking about this recently and feel it is a good topic for us all to consider. Some organizations are doing virtual conferences, and there will be more technical innovations coming in the future. With this article, I want to introduce some of these topics and ask for your thoughts and comments. Please note that none of the questions raised here represent plans for I-INCE or INCE-USA. They are simply some questions that need to be considered and which have already impacted other organizations. The current value proposition for our institution is fairly clear. Most members would cite the following primary benefits: • Conferences • Noise/News International It is also possible to envision doing short, virtual mini-conferences on specialized topics. Several years ago there were specialty conferences on sound quality, materials, and active noise control that were quite successful. Could these be done electronically? Would there be value in doing so? What should the cost be for attending virtually? Should the virtual attendee pay more or less for the conference? Should NCEJ be free to anyone who goes to the website, like NNI? Would this diminish the value of membership? If we had to add advertising to defray the cost of offering NCEJ this way, what would you think? How would this affect the perceived value of INCE-USA or I-INCE membership? Would this make it more or less desirable for you to publish in NCEJ? • Noise Control Engineering Journal • Digital Library • Certification • Training courses offered to prepare one for full membership or certification These benefits seem to represent real value, and most members seem to agree. So, where do we go in the future? People have talked about virtual conferences. Would there be a loss in value if you attended a conference over the Internet? You could see the delivery of papers and perhaps participate in discussions. However, there would be some loss in networking and the unexpected opportunities to learn from interactions in the exhibits or in the hallways of the conference center. It seems like many would still prefer to attend the conference in person. However, for some the cost or other issues may prevent being there in person. For such cases, a virtual capability might be a good alternative. Does this lessen the value for those who do attend? Does it increase the value for those can be there physically? I would be interested in your thoughts on this topic. 2014 September www.inceusa.org What about certification? Does it still provide value when it is easy to go online and review someone’s background and education on LinkedIn or somewhere similar? Should INCE-USA open up certification to non-INCE members? What should we charge for such an opportunity? Would $1,000 be too much? Should we make the Digital Library open to anyone at no charge? Would you see this as devaluing membership? It certainly would be good to have these 20,000 papers available to anyone interested in noise control. Would this lead to increased usage of this resource? Hopefully you will want to provide feedback. I will promise to share this feedback with I-INCE and INCE-USA officers and board members. These are issues that we need to consider; other professional organizations have already taken some steps along these lines. I appreciate your consideration and look forward to your response. NNI • www.noisenewsinternational.net • www.i-ince.org 5 Member Society Profile Welcome to the Swedish Acoustical Society! Svenska Akustiska Sallskapet or the Swedish Acoustical Society (SAS) was established as the focal point of interest in the field of acoustics within Sweden. According to its statutes, the Swedish Acoustical Society, through the organization of lectures, discussions, and other activities, encourages the development of acoustics. The SAS publishes a journal three times a year, which contains acoustic news and articles. Over the years, SAS has broadened the scope of its activities to encompass all areas of acoustics as well as several related disciplines-such as physiology and audiology. Initially, the activities of the Society were concentrated in Stockholm at the Royal Institute of Technology. A topic was chosen for a SAS meeting, a paper was presented and a lengthy discussion followed. Later, the activities were expanded to include Gothenburg and Malmo, and indeed the whole of Sweden. It has now become a tradition of SAS to hold an annual meeting with several lectures and a social function. In 1954, SAS played an active role in the formation of the Scandinavian Acoustical Society (NAS), and the first meeting was held in Copenhagen, Denmark, with Paavo Arni from Finland as president. Members of NAS (today NAM) are the four acoustical societies of the Scandinavian countries. The societies take turns hosting the Scandinavian Acoustical Meetings. For example, SAS hosted the Scandinavian Acoustical Meeting (NAM 98) in Stockholm during three days of September in 1998 with Leif Akerlof as chairman. SAS continues its involvement as a society dedicated to spread knowledge in the field of applied acoustics, particularly as related to the noise problems in the world. SAS is an active member society of International INCE. In 1990, SAS hosted INTER-NOISE 90 at the Chalmers University of Technology in Gothenburg. The number of registered delegates at that congress exceeded 800 with participants coming from 39 countries. The largest delegation was, of course, from Sweden with over 200 participants. With the theme Science for Silence, the congress was focused on the need for applied science to support future improvements in environmental noise levels. For more information, visit us at www.akustiska-sallskapet.org. NNI Membership is open to all interested parties who wish to promote acoustics in Sweden. Members also receive our newsletter each trimester and information about activities organized or sponsored by SAS. Online subscription to Acustica Acta Acustica has been included in the membership fee since 2011. www.odeon.dk Room Acoustics Software … brings measurements and simulations together 6 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September Public Outreach Workshop on Noise in Communities and Public Areas Darlene E. Kilpatrick, Lawrence S. Finegold, and David Sykes INTRODUCTION Noise is a significant social and public health problem, particularly in urban areas. Documented health effects include hypertension, increased risk of stroke and heart attack, sleep disturbance, speech interference, annoyance, compromised enjoyment of natural quiet, and a general decrease in the quality of life (WHO 2011). Protected natural areas, flora and fauna are also affected; noise exposure in national parks and wilderness areas has been documented by the US National Park Service (NPS) (Reid and Olson 2013). Successful resolution of these problems requires informed public support for improved noise management policy at all levels of government. One method of stimulating collaboration and gaining public support is hosting free public outreach workshops. On August 27th 2013, the public outreach workshop “Noise in Communities & Natural Areas” was held in Denver, Colorado, USA, and co-chaired by Towards A Quieter America (now “Quieter America” [QA]) and the NPS1. The workshop was held concurrently with the Institute of Noise Control Engineering (INCE) Noise-Con conference. This was the fourth in an ongoing series of free public outreach workshops in the United States on community and environmental noise management organized by QA. Previous public outreach workshops in the US were held in Baltimore (2010), Seattle (2011), and New York City (2012). 1 NPS does not endorse or promote any product, conference, foundation, or organization by their involvement in Public Outreach Workshops. 2014 September www.inceusa.org These free public workshops comply with the National Academy of Engineering’s (NAE) recommendation for organized public outreach to educate & inform Americans about exposure to noise, the effects of noise, noise policy, and noise control options (NAE 2010). The QA workshops are endorsed by the National Research Council Transportation Research board/ADC40, The National Hearing Conservation Association (NHCA), INCE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Technical Committee 2.6, and multiple American National Standards Institute (ANSI) Working Groups. Quieter America was and continues to be chaired by Lawrence Finegold and David M. Sykes with Darlene Kilpatrick as the Executive Assistant. The primary sponsor of the “Noise in Communities and Public Areas” workshop was the Michiko So Finegold Memorial Trust (MSFMT) which also sponsors QA. BACKGROUND: MICHIKO SO FINEGOLD MEMORIAL TRUST The MSFMT came to fruition following the tragic loss of a dynamic, passionate, and caring woman: Dr. Michiko So Finegold. Michiko passed away suddenly in 2011, entrusting her husband, Lawrence Finegold, with her legacy. Mr. Finegold established the MSFMT to honor his late wife and continue their important work. Michiko So was born in Tokyo, Japan in 1954 to a prominent and influential family. She graduated from Nihon University with a PhD in Engineering Science (Field Study of Noise Effects and Community • www.noisenewsinternational.net • www.i-ince.org Evaluations Concerning Aircraft Noise) in 1983. She served as a lecturer at Nihon University from 1983-2000 where she taught courses on various topics including Neighborhood Noise and Insulation Programs. She studied environmental noise problems related to traffic, industrial, residential and commercial areas. As a result of her work Dr. So was awarded the Institute of Noise Control Engineering, Japan (INCE/J) Encouragement Prize in 1987. During her career she made significant contributions to identifying and addressing a wide variety of noise problems in Japan. In 2000 Dr. So married Lawrence Finegold and together they began to work internationally as consultants on noise effects research issues and noise policy topics. In May 2010, Dr. Michiko So Finegold, her husband Mr. Lawrence Finegold, and Mr. David Sykes formed what is now “Quieter America” to organize outreach in support of noise research and public policy. The Michiko So Finegold Memorial Trust collaborates with QA to stimulate public interest in acoustical science and noise control and to assemble scientific and professional organizations into a joint task force capable of having an effective voice in public policy. Their focus is to use scientific data to raise awareness on the effects of noise and influence public policy through outreach. In addition, QA stimulates problem-solving through dialogue with leaders in national and international governments, government agencies and NGOs. The foundations for their current work are the publications 7 Burden of Disease From Environmental Noise (WHO 2011), Technology for a Quieter America (NAE 2010) and Protecting National Park Soundscapes (Reid and Olson 2013). These documents provide the basis for a profession-wide strategic road map for acoustical science and noise control engineering. WORKSHOPS Each public workshop tailors its topics to be relevant to the communities in which they are held. For example, cities in Colorado such as Denver and Colorado Springs have progressive noise regulations to protect their health and wellbeing as well as the sanctuary of the mountains and open spaces. Over 150 people participated in the Denver workshop. Participants included concerned citizens, employees of the NPS, the US Forest Service, nongovernmental organizations, city/state government officials, and INCE members from the concurrent Noise Con conference. Presenters included international scientists, INCE and QA members, university researchers, naturalists and public figures. Topics included the effects of noise on human health, current noise policy, recent research and potential solutions. Issues such as quiet in natural areas and the loss of natural sound were addressed through the vital collaboration with NPS; primarily by Dr. Kurt Fristrup, Branch Chief for Science and Technology in the Natural Sounds and Night Skies Division of Natural Resource Stewardship and Science. The workshop offered a unique forum where noise experts, Noise Con attendees, and the public could interact. The public format allowed engineers and policy-makers to hear what is important and where our current regulations or technologies fail the average citizen. Presenters and INCE members dialogued with the public on steps they could take to reduce noise and increase quality of life. The workshop was divided into three 8 sessions: morning, afternoon and evening, with multiple keynote speakers. Each session was followed by a question and answer period with the presenters from that session and the attendees. SUMMARY OF PRESENTATIONS The morning session began with the introduction of the keynote speakers by QA chair Lawrence Finegold. The morning keynote speakers were Dr. George Maling (chair of the committee that produced Technology for a Quieter America [NAE 2011]) and Eric Wood (past president, INCE-USA). Dr. Maling summarized key sections of the Technology for a Quieter America report and emphasized the chapters on community noise, metrics for the assessment of environmental noise, the role of government and public information on noise control. Mr. Wood presented the difficulties of enforcing motorcycle noise ordinances at state and local levels. He also discussed potential solutions through education and behavior modification. This was followed by QA chairs Lawrence Finegold and David Sykes. Mr. Finegold discussed community-based environmental noise management, such as techniques available to local communities and governments to take pre-emptive and mitigating actions to reduce community noise. Mr. Sykes reviewed past and current national noise policies, the challenges associated with revising them and the importance of updating these policies after decades of neglect to increase their relevance in today’s society. The afternoon session began with introductions by QA chair David Sykes. The first presentation was by Bennett Brooks (Brooks Acoustic Corporation) who summarized the ANSI standards and provided guidance for the development of local noise ordinances that are appropriate for local circumstances. Mr. Brooks suggested that local ordinances should provide a technical basis to manage the local sonic environment and help communities decide which sources of noise need to be regulated to have an improved acoustical quality of life. Following Mr. Brooks, Nicholas Miller (Harris, Miller, Miller and Hanson, Inc.) discussed the complexities involved with defining, assessing, improving and preserving quiet areas. Mr. Miller also postulated that many of these difficulties are associated with differing human interpretations about what types of noise are considered desirable or undesirable in natural areas. This was followed by Dr. Jessie Barber from Boise State University who presented recent research on how traffic noise influenced habitat use by birds to where some habitats that were otherwise suitable were excluded solely due to the influence of vehicular traffic noise (Francis and Barber 2013). Dr. Barber also discussed how increased anthropogenic noise can be detrimental to the survival of many bird species. Eddie Duncan (Resource Systems Group, Inc.) discussed how he used public input to develop scientifically sound noise pollution policies for Vermont’s rural communities and the importance for the community input. Jan Jabben (National Institute for Public Health and the Environment, the Netherlands) talked about the importance of preserving and improving the areas of natural quiet such as urban parks and open spaces, particularly in densely populated areas. He discussed a study that rated public opinion on the accessibility and quality of urban parks and open spaces and how such data can be used to influence policy. Les Blomberg (Executive Director, Noise Pollution Clearinghouse) gave the final presentation of the afternoon session where he discussed how industrialization, particularly increased vehicular and aircraft traffic, has greatly reduced natural quiet. Mr. Blomberg presented a model to predict which public land had the highest level of natural quiet based on minimal amount of vehicle and aircraft traffic. www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September The evening session began with introductions of the keynote speakers by QA chair Lawrence Finegold. The evening Keynote Speakers were: Dr. Arline Bronzaft, Dr. Kurt Fristrup, Julie Zickefoose and Erik Lindbergh. Dr. Bronzaft discussed her research on the adverse impacts of noise on children’s classroom learning and the adverse effects of noise on mental and physical health. She is an author of “Why Noise Matters: A Worldwide Perspective on the Problems, Policies and Solutions” (Stewart and Bronzaft 2011). Dr. Kurt Fristrup from the NPS presented research on noise levels in national parks and the need to preserve the natural sounds of national parks. Dr. Fristrup talked about acoustical conditions in various national parks and presented models predicting sound levels throughout the continental U. S. He also discussed the coordination of NPS with the aviation industry to reduce air traffic over national parks. Radio host and renowned naturalist Julie Zickefoose talked about the basic human need for connecting to nature and wildlife, which she captured in her 2012 book, entitled: “The Bluebird Effect: Uncommon Bonds With Common Birds.” The final speaker of the workshop was aviator and entrepreneur Erik Lindbergh, grandson of the famed aviator Charles Lindbergh. Erik Lindbergh was an inspirational speaker who shared how he triumphed over adversity, reminding us that even in the face of seemingly impossible odds one can persevere through hard work, commitment and dedication. His current challenge and quest is to move the future of flying toward the use of electric aircraft to reduce aviation noise. SUMMARY OF PUBLIC COMMENTS There were numerous questions and comments from the attendees - too numerous to be included in this paper. However, we will summarize the most common questions and concerns. Common 2014 September www.inceusa.org complaints were about railroad noise and loud music from vehicles during nighttime hours. The railroad issue was in regards to the mandatory use of the horn when traveling through urban areas, which typically occurs at night when there is less vehicular traffic. The question arose from a local nurse who expressed concern that such noise could result in health issues. The panel explained that this horn use was initially developed for rural areas and that exemptions could be granted to individual communities. The loud music from “boom cars” was a challenging issue as local law enforcement officers are not provided with the means or personnel to measure the decibel level and enforce local ordinances. A panel member suggested that even if local law enforcement were able to measure the decibel levels, federal regulations are so technical they become impractical and prohibitive. There was an expression of overall frustration about the apparent lack of interest and apathy on the part of federal regulatory agencies regarding the issues of noise, particularly compared with current published research and policy coming from Europe. The panel explained that the difficulty in the US is that there is no longer a single federal agency responsible for monitoring noise issues. There are several agencies that have taken matters into their own hands. However, the current challenge has become one of counterproductive “turf wars” between these different agencies. Different measurement methods and metrics are used by the individual agencies resulting in inconsistent and incomparable results and little to no interagency communication. It was suggested by the panel and attendees that most of the general public has the ability to measure noise levels through applications on their mobile telephones. And while such measurements may not be consistent among individuals, “crowd sourced” data • www.noisenewsinternational.net • www.i-ince.org could provide a meaningful and significant foundation on which to build a larger body of scientific evidence to present to policy makers. Not all comments were those of doom and gloom and several success stories were shared. For example, in Estes Park, Colorado a league of women voters became concerned about the noise associated with commercial tourist aviation over nearby Rocky Mountain National Park. These women educated themselves on the issues of noise and local noise ordinance, engaged the public and were successful in proposing a ban on local air tourism which was enacted by the Colorado State Legislature. An attendee from Maine shared the successful upholding of noise limits on farm wind turbines in his local community through thoughtful discussions with local city planners. A panel member also pointed out the establishment of acoustic guidelines for schools. An overarching theme was that change needed to begin at the local level and that enacting and enforcing local noise ordinances would likely solve many of the problems. THE FUTURE OF QA AND MSFMT The Michiko So Finegold Memorial Trust and QA will continue to offer free public workshops to gain public awareness and support. The 2014 Noise Con in Ft Lauderdale, Florida will host the next QA public workshop. The workshop will focus on the effects of noise on marine life and birds. Lawrence Finegold and David Sykes continue to be active and influential participants in INCE, ICBEN, and other noise related organizations. The MSFMT will offer its first medal to award scientific excellence in advancing the quality of life through scientific research on the effects of noise at the International Congress on the 9 Biological Effects of Noise in Nara, Japan, in June 2014. Quieter America and MSFMT are also collaborating with Transcends Films to assist with the production of a documentary film on the effects of noise called “The Pursuit of Silence”. Quieter America believes in order to influence governments, agencies and NGOs, it is essential for established professional organizations to form an organized joint task force with shared goals that can awaken and catalyze public concern. These organizations must speak with one voice. To achieve these goals, MSFMT and QA are encouraging relevant professional societies to meet and agree on a shared agenda. The ultimate goal is to meet with US policymakers and create new policies and regulations that make the US a leader in noise policy once again. 10 LITERATURE CITED [1] Francis, C. D. and J. R.

The event provided an opportunity for the engineers who are early in their career (between 30 and 45 years old) to discuss the state of noise control engineering and the frontiers of future research and application. The JAFOE event is organized and hosted by the National Academies of Engineering for both the US and Japanese nations. This most recent JAFOE event was the 8th time for these two organizations to meet and discuss the latest information on four topics in engineering. Along with the session on Noise Control Engineering, this year’s session topics also included Bioimaging, Power Unplugged: Energy Harvesting and Power Transmission, and Field Robotics for Disaster Response (a longer description of each of these topics and the presentations on the individual topics are available at the JAFOE 2014 website: http://www.naefrontiers.org/ Symposia/JAFOE/32546/41283.aspx). Each topic included two invited speakers from each country to present their latest research and insights on the topic. This was the first time that noise control engineering had been discussed. We appreciate this year’s inclusion to the support from Proctor Reid at the US National Academy of Engineering and the generous financial contribution of Lawrence S. Finegold and the Michiko So Finegold Memorial Trust for the event.

Mr. Sato and Mr. Fullerton invited experts in the field of noise control engineering to discuss the topic of Noise Control Engineering in Healthcare Environments. The invited speakers included Shinichi Sakamoto from the University of Tokyo, Erik MillerKlein from SSA Acoustics in Seattle, WA, Mandy Kachur of Soundscape Engineering in Ann Arbor, MI, and Hiroko Terasawa of Tsukuba University, Tsukuba, Japan. Mr. Sakamoto presented his research and findings on the prediction, control and assessment of environmental noise. During his discussion, he focused on roadway and wind turbine noise assessments, which are issues that affect the public in Japan. Mr. Miller-Klein discussed the changes to the healthcare systems in the United States and how acoustics and noise control will influence these changes. He cited research showing the link between low patient survey scores and the acoustical conditions in the healthcare environments. Ms. Kachur spoke further about acoustics in healthcare environments and what can be done to improve the outcomes of patients and reduce the stress and 2014 September www.inceusa.org Hiroshi Sato introducing Mandy Kachur’s discussion on the acoustics in healthcare environments. errors of the staff. She highlighted case studies showing how improved acoustical conditions have been implemented on recent healthcare facility projects. Mrs. Terasawa presented her research of sonification, where bioelectric signals and data are used to provide a positive and motivating feedback mechanism for rehabilitation patients. She also showed events where sonification of physiological data was used to produce modern music and art. The abstracts for each speaker that were submitted for the event appear on the following pages. • www.noisenewsinternational.net • www.i-ince.org The noise control engineering presentations generated positive feedback and intriguing questions about the further uses of the research and findings for improving the quality of life. The US NAE event organizer said she was not sure why the topic of noise control engineering had not be discussed in previous JAFOE events and that it should be included as a topic again in the future. Introductory slides for the event can be viewed here: http://www.naefrontiers.org/File. aspx?id=45039 NNI 13 Technologies on Environmental Noise Issues in Japan Shinichi Sakamoto, University of Tokyo, from JAFOE Environmental noise issues, transportation noises from road traffic, railways and aircrafts have been typical problems so far. Among them, the author has been studying prediction and countermeasure of road traffic noise. The prediction methods of noise by computation are roughly categorized in two areas; the one is an engineering method on energy-base and the other is a precision model based on wave theory. Through research on energy-based calculation method, the author has been concerned with development of ASJ 14 RTN-Model, which is now used as the standard engineering calculation model for environmental noise assessment in Japan. In my presentation, the noise prediction model is firstly introduced. Originally the author studied wavebased numerical analysis on acoustics. Although the application of the wave-based numerical analysis is limited because it focuses on a comparably detailed area, the method can be efficiently used as a tool for precision modeling of road traffic noise. Furthermore, the method also can be utilized for the development of the engineering model. Such applications of the precision model are also introduced. As a novel environmental noise issue, wind turbine noise problem is being concluded. The author dealt with the issue and performed psycho-acoustical experiments. The outcome of the research will be introduced, and the current situation and the future developments of noise mitigation technology will be discussed. Presentation available here: http://www.naefrontiers.org/File. aspx?id=45024 NNI www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September Acoustics and the Patient Experience Erik Miller-Klein, PE, SSA Acoustics, LLP, from JAFOE The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys have brought increased focus on noise control engineering for healthcare environments. This survey asks a series of questions to recent hospital patients, and the scores have a direct impact on the facilities rating and the government reimbursements for medical services. The HCAHPS survey has one question on noise; “how often was the area around your room quiet at night?” This question does not lend itself well to normal noise control design metrics or mitigation design considerations. This has led designers, researchers and engineers to explore the connections between patient experience, and the noise control impacts that lead to improved scores, medical outcomes, and performance. This question requires a balance between psychoacoustic and effective noise control design to optimize healthcare environments and patient health. Hospitals are unique and complex acoustic environments filled with numerous noise sources, limited by strict hygienic requirements, and populated with critically sensitive occupants. Healthy soundscapes are paramount to the missions of hospitals: patients need to sleep and heal without environmental stressors; staff, patients, and family need to communicate accurately but privately; staff need to be able to localize alarms and calls for help. Numerous studies 2014 September www.inceusa.org Erik Miller-Klein speaking about the latest drivers for improved acoustics in healthcare environments in the US. show that hospitals are unacceptably noisy. There is also evidence to suggest that poor hospital soundscapes can be detrimental to occupants. For example, noise in hospitals has been suggested to increase patient risk for cardiovascular response, pain, intensive care delirium, fragmented sleep, and reduced recuperation.

Bd. Cert., Soundscape Engineering LLC Unnecessary noise, then, is the most cruel absence of care which can be inflicted either on sick or well. Florence Nightingale, 1859 In the 150 years since Florence Nightingale wrote about the adverse effects of noise on hospital patients, others have noted the problem, but it is still not recognized as a major cause of patient harm. Noise control in U.S. healthcare environments has grown as a priority after the publication of landmark papers in 2004, documenting the gradual and detrimental rise in worldwide hospital noise levels since 1960 and the resulting noise-related medical errors. Consequently, noise in healthcare environments is becoming recognized as a serious health issue, increasing staff stress and absenteeism, hindering patient healing, and causing patient injury and fatalities. In the U.S., new regulations and financial incentives have been put in place in the last five years. Since October 2013, government reimbursement to hospitals is adjusted based on the scores of a standardized patient assessment survey, on which noise is consistently rated worse than any other category. Also, the Joint Commission, an independent, notfor-profit organization that accredits and certifies healthcare facilities, has made alarm safety a national patient safety goal starting in 2014, signaling that hospitals must give it top priority. Regarding the built-environment, the 2010 edition of the Guidelines for the Design and Construction of Health Care Facilities, a document used or referenced in 42 American states and in 60 countries, has a greatly expanded acoustics section covering a wide range of 16 topics from acoustical finishes and sound isolation to paging systems and noiserelated safety risk reduction. Furthermore, sustainable building design initiatives, which have become increasingly popular in the U.S., have included acoustics as a design consideration since 2009. Noise engineers and medical personnel generally had been working separately on noise issues, with limited progress and implementation of their findings. With the new urgency for improvement, multidisciplinary teams have been formed to produce actionable research and evidence based design initiatives. This collaboration between medicine and engineering has produced data on physiological responses, healthcare outcomes, and economic impact, which all have more influence on policy making than the historic assumption that noise is nothing more than an annoyance. While progress has been made in the builtenvironment, changing healthcare worker behavior and the healthcare culture has proven to be more challenging. Though obtaining funding for these studies presents challenges, a growing body of research about the harmful effects of noise in the healthcare environment along with the new financial and regulatory incentives has advanced noise control in healthcare facilities to a top priority. The end goal is improving patient outcomes, increasing staff comfort and establishing a healthy environment for all.

People observe and understand the surrounding environment by listening to sounds, and express our response back into the environment by making sounds. Our data sonification project borrows this paradigm: We represent biological information with synthesized sounds so that people can intuitively understand and respond to the data in an embodied and enjoyable manner. In this talk, I will present our research on (1) auditory biofeedback system for physical therapy and (2) brain wave sonification for multi-channel EEG data analysis. By listening to his/her own motion, people can move more efficiently and easily. Our auditory EMG biofeedback system (AEB) transforms the muscular movement data into sound in real-time, to help blind and sighted people undergo physical therapy with better control and comfort. In the evaluation test, blind people conducted a gripping task more accurately and easily with AEB, while sighted people also reported increased easiness with AEB. Another experiment showed that both auditory and visual biofeedback systems offered comparable efficiency in helping ankle-joint rehabilitation task even for sighted people. 2014 September www.inceusa.org Sonification is valuable as data analysis tool as well: With our EEG data sonification, people without knowledge of neuroscience easily detect the presence of a special kind of brain activity (steady state responses). Furthermore, the synchrony across EEG channels and the location of strong activity are precisely understood by sonification: Our evaluation test showed that subjective judgments with sonification were in agreement with the results of statistical analysis. These studies suggest that sonification can be an intuitive alternative for EEG data analysis to meticulous computational methods.

People need to escape this pollution and access quiet places to work, relax and live a healthy life. Such ‘quiet areas’ should be protected under EU legislation, but how does this work in practice? When we think about noise pollution, we often think about loud music or a neighbor’s barking dog. But in most cases, the real health problems are caused by long-term exposure to noise from road traffic, railways, airports, or industry. A quiet area is not necessarily silent, but rather one that is undisturbed by unwanted or harmful sound created by human activities, according to the 2002 Environmental Noise Directive. Indeed, some types of noise such as the sound of running water or birdsong are usually perceived as enjoyable. This means that it may not be possible to define a quiet area by just measuring decibels. A new European Environment Agency (EEA) report, ‘Good practice guide on quiet areas’, provides guidance and recommendations for authorities who need to identify and maintain these places. Its publication marks International Noise Awareness Day, 30 April 2014. Hans Bruyninckx, EEA Executive Director, said: “When we think about noise pollution, we often think about loud music or a neighbour’s barking dog. But in most cases, the real health problems are caused by long-term exposure to noise from road traffic, railways, airports or industry. Quiet areas are important because they can provide respite from noise, ultimately improving quality of life.” 18 Image © Travis Isaacs The European Soundscape Award 2014—Open for Applications Another approach to the problem of noise is the idea of soundscapes, creating healthier and quieter environments. The European Soundscape Award 2014 aims to draw attention to the most innovative product, campaign, innovation or scheme solving a noise problem. The award is a joint initiative of the European Environment Agency (EEA) and the Noise Abatement Societies of the Netherlands and UK. The deadline for submissions is 18th August 2014. More information. Noise App The EEA has developed NoiseWatch, an app which measures and maps noise levels. Over the last two years, NoiseWatch has received more than 155 000 citizens’ noise ratings from around the world. On 8 May, the EEA received a World Excellence Award for the app at the Geospatial World Forum. Coming Up Later in 2014, the European Environment Agency will publish its first Europe-wide noise assessment report. It will draw on data from Member States, highlighting the main sources of noise in Europe as well as its impacts on health and the environment. EuroNoise2015: May 31–June 3 Euronoise 2015, the 10th European Congress and Exposition on Noise Control Engineering, will be held at the heart of Europe where the first treaties leading to the creation of the European Union were signed. Acousticians and noise experts from all over the Europe will gather for the event on noise control, and soundscape in Europe, organised by the European Acoustics Association.

NNI 21 Asia-Pacific News ���������������������������������������������������������������������������������������������������������������������������� Quiet, Please! Hong Kong Is Suffering from Severe Noise Pollution. By Albert Lin Hong Kong is too noisy because, as a rule of thumb, not only are some members of our industrial, construction and commercial sectors uncaring about the noise their operations create, but too many of our flat-dwelling residents are seemingly deaf to the noise they generate. The root cause of today’s noise pollution in Hong Kong is poor planning in the past coupled with cramped development. With its limited land supply Hong Kong’s expansion had only one way to go— upward. But each high-rise added to population density involving ever greater numbers of people crammed into multi-story accommodation on either side of the harbor. And so, to accommodate increasing road traffic, we saw the construction of elevated highways that in some cases run just outside families’ living rooms, which brings us to our biggest single noise problem today—noise pollution from traffic, affecting more than 1 million people. And the reason for our noisy roads is that Hong Kong has a gross imbalance of motor vehicles compared with road supply. These statistics put it very plainly—there are 318 licensed vehicles for every kilometer of road, and 70 percent of all vehicles on our roads are private cars—a total of 464,595 of them. Happily, more than 30 km of barriers and screens have been erected along our new roads since 1990, providing a buffer against traffic noise for New Territories residents living nearby. Specially paved low-noise road surfaces are also being 22 used to reduce traffic noise. But such noise-amelioration measures simply cannot be applied to old, existing urban roads, except if they are to be re-surfaced—which would in turn involve major traffic diversions. Returning to our noisy industrial/ commercial operations, sometimes the explanation is that noise-mitigation measures haven’t been fully introduced because they cost money and affect the company’s profits. Often only the barest possible steps are taken, prodded along by prosecutions launched by the Environmental Protection Department (EPD). Although set up in 1986, the EPD only got its “teeth” three years later, when the Noise Control Ordinance was passed. This empowered its inspectors to take offenders to court as they struggled to get a grip on the runaway noise pollution that was beginning to seriously affect our living standards. The worst offenders in those days were the builders’ pile drivers crashing away to create the solid foundations of construction projects. Unremittingly they thumped away at least 12 hours a day as our economy boomed and residential and commercial developments blossomed across the urban areas. Today pile-driving is limited to three to five hours a day in built-up areas, quieter machinery must be used and various noise-abatement procedures exercised on site. Nevertheless some anti-social construction companies still flout the regulations and seem to regard fines for noise offences as an overhead.

It has a very interesting concept: can the influence of technology on human actions and decisions be considered morally good or bad, or is it the technology itself that has some moral value? Are technical artifacts (machine guns, electric chairs, nuclear bombs) just passive instruments to be used for good or bad or does their very existence actively shape the human condition? Another way of putting it is: are the morally positive (or negative) aspects of technology due to the way humans use it or the way technology affects human life? No clearer example of the latter is the ubiquitous use of cell phones in airplanes, classrooms, bus stops, and so on. The editors note that stories that stress the positive aspects of technology tend to praise humans for their astute use of technology while those stories stressing the negative aspects place blame on the device(s). So the issue is whether artefacts are particularly good or bad agents. In the past, and traditionally thought, there was no issue. Only acts of agents, or agents themselves, would be considered morally good or bad. (I am leaving out the possibility that some sort of “god” determines anything.) The thing, artefact, used was inconsequential. In a way, this makes sense for we would have problems calling a stop sign good and a gun bad. 2014 September www.inceusa.org But then, it is clear that technical artefacts do influence human behavior. (Hmmm. Here is a semi-automatic rifle, I need to make a statement, and I will go to the school and kill a bunch of kids and then myself. That will show them.) So, if technical artefacts do affect actions, maybe they can be thought of as morally good or bad. But keep in mind that technical artefacts are things built by people for some purposes, or some ends, and these ends cannot be separated from the artefact. List of the 13 chapters, done by a variety of authors, including some by the editors: 1. Introduction 2. Agency in humans and in artefacts: a contested discourse 3. Towards a post-human intra-actional account of sociomaterial agency (and mortality) 4. Which came first, the doer or the deed 5. Some misunderstandings about moral signifi cance of technology 6. “Guns don’t kill, people kill”: values in and/or around technologies 7. Can technology embody values 8. From moral agents to moral factors: the structural ethics approach 9. Artefactual agency and artefactual moral agency 10. Artefacts, agency, and action schemes 11. Artefactual agents and their moral nature 12. The good, the bad, the ugly...and the poor: instrumental and noninstrumental values of artefacts 13. Values in chemistry and engineering • www.noisenewsinternational.net • www.i-ince.org The chapters are condensed and references follow each. The book does not provide answers but rather a compilation of arguments (to me, both sides legitimate) on the morality of artefacts. For example, should some artefacts be destroyed because, by themselves, they are “bad” like ICBMs, nuclear power plants(?), and chemical weapons? Lots of people would agree. Similarly, do people kill people or do guns kill people? In a way, both are true. The Moral Status of Technical Artefacts is a tough but great read. But it is an important book, for it gives insight as to the role of what we as engineers produce and how that is used, in a moral sense, by our customers. Highly recommended. Richard J. Peppin Engineers for Change, Inc.

It is a handy reference for those interested in how animals deal with the natural world and the noise in which they have evolved, as well as how they attempt to compensate for a world of increasing noise pollution. 27 The book begins with a short review of signal detection theory and presents the premise for the evolution of communication as it relates to both the animal produc ing the signal, the intended receiver and the potential for errors in communication between the two. This is followed by a number of chapters on the most apparent condition of the communication-in-noise problem, that of acoustical communication. Examples of challenges faced by the signal producer and the receiver, as well as solutions to those challenges, are provided for insects, fish, anurans, birds and marine mammals. The Lombard effect, frequency shifting, temporal variation in calling and comodulation masking release are but a few of the topics discussed in various animal-specific contexts which is useful for understanding how these generalized phenomena vary in use by the niche that each animal exploits. Not to be overlooked, the book also contains several chapters addressing communication in noise from a perspective of visual, electrical and chemical communication. The book concludes with a chapter on the issue of anthropogenic sound and conservation. The chapter rightly opens discussion of the issue from the different perspectives of conservation and anthropogenic noise in the terrestrial and marine environments. The marine environment has received more attention than terrestrial environments in this regard which might seem surprising given the relative ease with which habitat perturba tion can be seen in terrestrial habitats. Yet, sound travels much more effectively underwater than in air and some marine organisms may have acoustic active spaces that range in excess of tens of kilometers, well beyond the air-borne acoustic range of terrestrial mammals. Couple this with some of the dramatic stranding events involving charismatic whales exposed to high-powered sonar systems and it is easy to understand how public opinion has more aggressively pushed noise the 28 conservation effort in the oceans. The chapter discusses the various approaches to trying to determine how anthropogenic sound impacts animals including a discussion of several specific models currently employed. The difficulties of relating acoustic disturbances to predicting biological impacts to individuals and populations are presented and subsequently linked to mitigation and management practices. The inherent difficulty of mitigation and management, in light of little supporting scientific information, is an important topic of study for any scientist interested in the noise pollution issue. This book is an excellent resource for individuals interested in the emerging issue of the impact of anthropogenic sound on animals, those interested in how animals have evolved to mitigate noise interference in communication and comparative biologists and bioacousticians interested in evolutionary solutions to noise across taxa. The book has a place on my bookshelf right next to Marine Mammals and Noise and complements it well with the updates it contains on the ocean noise issue. Dorian S. Houser National Marine Mammal Foundation, 2240 Shelter Island Drive, Suite 200,92106, USA [email protected] Architectural Acoustics, Second Edition Marshall Long Academic Press/Elsevier, (2014), 929 pp., hardbound, 119.95 USD, ISBN 978-0-12-398258-2 This book is a thorough compilation of acoustic principles and applications for room acoustics, sound isolation, noise control and sound reinforcement systems. From the author’s preface, the book’s goal was to provide an organized approach to acoustic interactions combining theoretical background and practical examples to enable an intellectual framework for thinking about the subject matter. Architectural Acoustics admirably attains this goal. I have used the first edition of the book since 2006 for my Architectural Acoustics and Noise Control classes at Peabody Institute of Johns Hopkins University. The book has been well received by students and the chapter topics are logically organized to enable effective teaching. Of particular note is the presentation of data and figures, all which use the same graphical formatting, giving a unified appearance that is easy to comprehend. The book comprises 22 chapters arranged in a logical sequence starting with historical perspectives, progressing to acoustic and perceptual fundamentals, outdoor sound propagation, sound isolation, mechanical vibration and noise control, room acoustics applied to differ ent building types, sound reinforcement systems and finally acoustic modeling. The first chapter covers acoustic history, starting with the Greeks, with a primary emphasis on religious and music performance buildings and featuring prece dent setting examples. Chapters 2 and 6 review acoustic fundamentals to include a general description of sound, source character ization, levels and loudspeakers to aid readers with the chapter topics that follow. It would seem apt that the material in Chapter 6 might better follow Chapter 2. Basic psychoacoustics is presented in Chapter 3 with emphasis on loudness, speech intelligibility, health and safety and audibility of sound reflections enabling readers to understand the perceptual implications of acoustic design. Chapter 4 addresses acoustic measurements and metrics to include basics of www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September microphones and sound level meters, quantifying environmental noise and an introduction to specialized measurements such as time delay spectrometry, sound intensity and speech intelligibility. My one criticism here is the over reliance on RASTI for speech intelligibility assessment. Work by Peter Mapp and others have shown this metric not to be as accurate as the full STI or abbreviated STIPA metrics. Chapter 5 reviews environmental noise with a particular emphasis on exterior sound propagation, barriers and traffic noise modeling. Of interest is the thorough description of sound absorption by air. Sound reflection and absorption are the topics of Chapter 7 with emphasis on coherent reflections, reflections from finite objects, absorption mechanisms and special sound absorbers such as panels and resonators. Sound reflections from ceiling panel arrays are covered based on the work of Rindel. Chapter 8 is a logical sequence to the previous chapter and describes the theory of sound propagation in enclosed spaces, starting with one-dimensional pipes and ducts and progressing to three-dimensional spaces with explanations of room modes, diffuse field theory sound propagation, reverberation equations and examples where deviations from diffuse field behavior occur. Chapters 9 and 10 cover sound transmission loss properties and sound transmission in buildings. This reviewer has found these two chapters to be one of the best presentations of these topics in an acoustics book. Chapter 9 addresses sound transmission loss theory for various idealized panel configurations. Chapter 10 is more practical and covers sound transmission for various conditions: reverberant-to-reverberant, free field to-reverberant and transmission into 2014 September www.inceusa.org absorptive spaces and through large openings. A unique feature is the treatment of the direct field transmission component for reverberant conditions and sound levels near and remote from the radiating surface. One minor criticism is the use of the term “R” for transmission loss which is not consistent with North American nomenclature. Vibration and vibration isolation are the subjects of Chapter 11. Its placement in the book, between chapters on airborne sound transmission and structure-borne sound transmission may seem out of place but makes sense as approximately one-fourth of this chapter addresses floor vibrations from human activities. The theory of single and double degree of freedom vibration-isolated systems is reviewed, along with practical applications of vibration isolator selection for mechanical equipment and support of vibrationisolated equipment. Chapter 12 covers noise transmission in floor systems with review of airborne, impact and floor squeak noise. An interesting aspect of this chapter, which differs from other acoustics books, is separating impact noise from walking into footfall and structural deflection components. These discussions, plus the cited references, have provided new understanding of these transmission mechanisms to this reviewer. Now I know the cause of those pesky floor squeaks in my house! Noise generation and control for mechanical systems are described in Chapters 13 and 14. The first chapter reviews mechanical equipment, both air handling and refrigeration devices, in terms of its functions and noise generation. Chapter 14 briefly reviews sound attenuation in ducts, plenums, sound attenuators and duct breakout and break-in phenomena, concluding with a • www.noisenewsinternational.net • www.i-ince.org typical mechanical system noise prediction calculation. Chapters 15 and 16 provide an overview of issues relating to acoustic design for multi-family dwellings and office buildings. Both chapters have an emphasis on speech privacy and considerations for mechanical equipment noise control. Guidance is provided on sound iso lation and privacy expectations as related to assembly construction and acoustic performance ratings. Design of rooms for speech is the topic for Chapter 17. Issues include general design criteria, sightline analysis to maximize direct sound propagation, room shaping, reverberation limits, comparison of different speech intelligibility metrics and applications to different room types. An interesting feature is the section on restaurant design. Many concepts in this chapter are directly applicable to the following chapters on music and multipurpose auditoria. As an extension of Chapter 17, sound reinforcement system design, is covered in Chapter 18, starting with a review of different loudspeaker types and following with design concepts for system electronics, loudspeaker directivity parameters, and lastly, computer modeling to include information on loudspeaker coordinate geometry. Chapter 19 covers design of concert and opera halls. The chapter condenses much of the work from the past 30 years with emphasis on contributions by Barron, Beranek and Bradley. The chapter concludes with a survey of significant venues summarizing physical and acoustic data for each. Chapter 20 describes acoustic design for multipurpose auditoria, recital halls and worship house sanctuaries to include 29 illustrative examples. The chapter supplements material from earlier chapters with diverse subjects such as stage shell, pit and platform design, variable acoustics (both passive and active), coupled chambers and integrating sound reinforcement systems. The design of small rooms is reviewed in Chapter 21. Topics include room modes, effects of discrete sound reflections, lowfrequency sound control, loudspeaker placement, diffusion and sound isolation for recording, rehearsal and listening rooms. The acoustic design for scoring stages and Foley studios is a subject not covered in other acoustics books. The last chapter reviews acoustic modeling, ray tracing and auralization as means to predict and evaluate room acoustic behavior. Information in this chapter will be useful to help understand commercial room acoustic programs that are available. In summary, the second edition of Architectural Acoustics provides a comprehensive overview to the many aspects of architectural acoustics, sound isolation, equipment noise control and sound reinforcement systems, balancing both theoretical and practical con siderations. A reader with no background in acoustics will be able to understand the topics because of introductory material presented before relevant chapters and the author’s unambiguous writing style. This book will serve as an excellent textbook for a yearlong course for upper level undergraduate or graduate students. Practitioners will find much value in the concise summaries contained in this revised volume.

W. Norton & Company, New York, NY (2014), 321 pp., (including bibliography & index), 26.95 USD, hardbound, ISBN 978-0-393-23979-9 A reverberation time of 75 (seventy-five) seconds? A cicada that can generate a sound pressure level equal to that of a pneumatic drill? You better believe it. Following in the footsteps of Rodolphe Radau and its 19th century Wonders of Acoustics. Or the Phenomena of Sound, Trevor Cox takes on the reader in an incredible voyage around the world, looking for (and discovering) the most reverberant place on earth, playing an organ constructed out of underground caves and taking us to a concert where the instruments are made of ice, to name just a few stops along the journey. And yes, we get to learn some fascinating things about the animal kingdom and its sounds, including that the African Cicada can generate an SPL of 107 dB at 50 centimeters. But this book goes far beyond putting some interesting facts about sound together. The author is able to actually bring the science of sound into a format that is readily accessible to readers without formal scientific training and still remain satisfying to those who like to approach the topics from a more rigorous fashion. Rather than simply stating results and findings, Trevor Cox actually engages the reader into the discovery process and even those with extensive training in acoustics will actually have no choice but to accept the reality that there are a lot of things about sound that one may not have known about; I know this for a fact because that’s what happened to me as I started to read this wonderful book. The clarity of the writing is outstanding; Trevor Cox is always focused on guiding the reader into that moment where “whoa” is the only appropriate response to the discovery. He uses fun, puns, self-deprecation, skepticism and superb endnotes to create chapters that read like mystery page-turners and leave the reader eager for the next stop on the discovery voyage. This book should be required reading for anyone who is looking for amazement in everyday life; it will turn readers into informed listeners, and that by itself is a rather impressive achievement.

The considered facets of performance include capacity, delays, economic costs, noise, emissions and safety. Several of the contributions also examine policies for managing congestion and allocating sparse capacity, as well as for mitigating the externalities of noise, emissions, and safety/ risk. The book is a compilation of articles devoted to methodologies for analyzing, forecasting, and improving the performance of airports and air traffic flows with the following www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September 10 chapters dealing with all aspects of airport functionality: • Modeling Airport Landside Performance, dealing with levels of service, check-in, departure lounges, baggage claims, etc. • Decision Support Systems for Integrated Airport Performance Assessment and Capacity Management, discussing modelling concepts • Measuring Air Traffic Management (ATM) Delays Related to Airports: A Comparison between the US and Europe • Forecasting Airport Delays • Airport Operational Performance and Its Impact on Airline Cost • New Methodologies for Airport Environmental Impact Analysis wrestled with for decades, namely that while aviation noise levels have decreased significantly in absolute terms over the last several decades, annoyance from and resistance to airport operations remains unchanged (or in some areas is even increasing). The authors of Chapter 6 review the effects of noise on people, various policy approaches that have been undertaken, and models for predicting noise exposure from aircraft operations. Hansen et al. propose that better models that address policy impacts, not simply the impacts from the pollutants, should be developed. These policy models would allow for objective comparison of various policy alternatives and would also allow for evaluation of the impacts of multiple pollutants (i.e., tradeoffs). • Airport Safety Performance In short, Chapter 6 proposes that better models would enable comprehensive policy analysis that would put the impact and effects of noise in context with other environmental pollutants and allow for more effective decision-making. • Scheduled Delay as an Indicator for Airport Scheduling Performance • Implementation of Airport Demand Management Strategies: A European Perspective • Design and Justification for MarketBased Approaches to Airport Congestion Management: The US Experience, discussing slots, small communities, and so forth. I would recommend Chapter 6 of Modelling and Managing Airport Performance for those seeking a concise summary of the range of environmental challenges facing airports. Because this review is being published in the Noise Control Engineering Journal, the focus of this review will be on Chapter 6, “New Methodologies for Airport Environmental Impact Analysis,” by Hansen, Ryerson, and Marchi, which focuses on four key undesirable byproducts of airport and aviation operations: noise, water runoff, air pollutants and Greenhouse gas emissions (GHG). Applied Structural and Mechanical Vibrations Theory and Methods, Second Edition The discussion of noise in Chapter 6 is thorough and informative. It addresses a conundrum that practitioners have Paolo L.

The pages are not gathered and sewn into signatures. Instead they are glued together with a thick layer of glue. The paper is good but after extensive use over a period of years, the book will fall apart. This is unfortunate because this is the kind of book that you might like to keep on your shelf as a reference. When I accepted the book to review, I thought that it was a graduate level textbook. However, there are no problems at the end of each chapter. After I had read a few different parts of the book, I looked at the short biography of the author. The author graduated with a degree in an area of physics and then entered the field of vibration engineering. I have met others who followed the same path and I am one of them. The area of mechanical vibrations, as well as acoustics, is based on analytical mechanics, experimental mechanics, as well the electrical engineering aspects of data acquisition and signal processing and the more artistic area of the display of quantitative information. Anyone working in this field is bound to interact with people who use the particular vocabulary of physics, mathematics, mechanical or electrical engineering. I think this book successfully addresses that problem in a fairly systematic way. The book consists of roughly four parts: a preliminary introduction (pp. 1–118), SDOF, MDOF and continuous vibration systems (pp. 119–420), experimental modal analysis (pp. 421–476) and random vibrations (pp. 477–584). There are also two appendices: vector and matrix algebra and assessment of vibration intensity. There are 117 references, among which I recognized several helpful texts and handbooks. 31 The preliminary introduction includes some fundamentals like linearity, what degrees of freedom means, complex notation, beat phenomena, physical description of motion (displacement, velocity and acceleration), idealized mechanical components (mass, spring and dashpot), and analytical mechanics. These fundamental discussions show clearly to an electrical engineer the definitions of mechanical components that are analogs of inductors, capacitors and resistors. There is an introduction to Fourier series and transforms that includes some sophisticated concepts and places them in the field of mechanical vibrations. The chapter on analytical mechanics is thorough and includes Hamiltonian and Lagrangian methods. In some chapters “bra-ket” notation is used while in others, integral and differential notation. The part on vibrational systems includes a chapter on SDOF systems: the effects of damping and definitions of quantitative descriptions, such as damping ratio, logarithmic decrement, displacement velocity and acceleration resonant frequencies, the effects of damping and equivalent viscous damping, frequency response, shock response and transient response. Approximate methods for estimating the response of a system that is approximated as an SDOF are given, too. The chapter on MDOF contains several cases of increasing complexity before presenting matrix formalism and increasingly more complicated conditions such as proportional and non-proportional damping and the response to excita tion. The chapter on continuous systems presents the solutions to several wellknown problems: the string, membranes, thin rods and thin circular and rectangular plates. The chapter on MDOF and continuous systems includes the modal approach and the approximate 32 Rayleigh–Ritz method. Numerical examples are given sometimes. The third part on experimental modal analysis is only one chapter, which used to be three chapters according to the preface to the second edition. In spite of this, I found the chapter to be clearly written and introduced me, who has never performed experimental modal analysis, to the subject. The chapter includes three primary questions to be answered before any experiment is performed: “What do we need to know,” “What is the desired outcome,” and “After the experiment, what steps are taken and why?” The two main purposes of performing modal analysis are to determine the levels of response of a specific structure or to validate a model of the structure. The chapter does not include electrical issues around recording the data, but does include mechanical considerations, such as the mass of an accelerometer and the mounting of the structure. Specific examples of Bode and Nyquist plots of the receptance, mobility and accelerance are shown with clear explanations of the behavior. While reading about the utility of log–log plots, I remembered being told by a colleague that long ago, one goal of applied scientists was the creation of graph paper that presented any data as a straight line. The chapter does not present specifics about a list of 25 popular methods of parameter estimation but a comprehensive reference is given. From the preliminary information given in the chapter, I felt confident that I could learn any of the methods. The fourth part consists of two chapters on probability, statistics, stochastic processes and random vibrations. Basic definitions, a few specific distributions, marginal distributions and random vectors are included, some with more detail than others. There are several references given for a deeper discussion of any topic. The last chapter presents material on stochastic processes. I wish that the author had included a longer discussion of practical considerations of stationarity and ergodicity because these tend to be confusing to many people and data can be taken and analyzed improperly. However, the chapter does describe the properties, including bandwidth, of power spectral densities and the steady-state and transient responses of systems to stationary vibrations. Threshold crossing rate, peak distribution and fatigue damage from random excitation are presented for narrowband random vibrations. In summary, I found the book to be well written with clear explanations. I found only two typographical errors and I could easily work around them. I think that this book is a good reference book to have on the shelf to refresh your memory about some aspects of vibrations or to find a reference to deepen your understanding. It is also a good book for people – like physicists or electrical engineers – who have a technical background but not in this area of mechanical engineering. In my opinion, there are two deficiencies in this book. First, the book could be more useful if numerical recipes and numerical examples were included in more sections. Solved numerical examples can be useful for developing and using software. Second, a list of all symbols would also be helpful. However, the bottom line is that I am happy that I was given this book to review; I will keep it on my shelf and use it as a handy reference with clearly written verbal, mathematical and graphical descriptions.

Paul C. Etter CRC Press, Boca Raton, FL, (2013), 554 pp, hardbound, 215.96 USD, ISBN: 978-1-4665-6493-0 As with the prior editions, Etter’s fourth edition text is ideally suited for use by professional and student acousticians, acoustical oceanographers, applied mathematicians, sonar technologists and operations analysts and system engineers. The author assumes that the reader already has a basic technical foundation in underwater acoustics and the text therefore concentrates primarily on covering the wide-ranging variety of modeling approaches applicable to this area. The 2013 fourth edition of Paul C. Etter’s text entitled Underwater Acoustic Modeling and Simulation deals predominantly with physical and/or empirical modeling methods and approaches for predicting a variety of underwater acoustic phenomena including acoustic propagation, noise and reverberation occurring in the ocean environment. Practical information on the application of these models to sonar operation and performance and also the implementation of models over time (termed “simulation” by the author and introduced to the title and the text back in the third edition) are discussed in later chapters. New topics specifically added in the fourth edition include the impact on underwater acoustic modeling tools of a variety of more recent undersea subjects including marine mammal protection, the impact of increasing ocean acidification, undersea noise pollution, effects of climate change, marine wind farm development, etc. Etter’s evolution from the first edition of this book (entitled Underwater Acoustic Modeling and published in 1991) to the present fourth edition has occurred over a period of nearly four decades. Overall, looking back on the changes made to the book during that period with each new edition, it has been a fine progression. Real-world changes to the technical interest areas and priorities relating to underwater acoustics modeling (e.g., the shift in emphasis to acoustic prediction in shallowrather than deep-water environments) have successfully been incorporated into later editions over the years. Relatively weighty improvements and updates to the material 2014 September www.inceusa.org While the text is fairly detailed and extensive, this reviewer believes that it is intended primarily as an introductory or illustrative examination of a broad field of underwater acoustic modeling methods. As such, it is likely aimed more at graduate students and professionals interested in learning about the full spectrum of underwater acoustics modeling and simulation methods or classes of models rather than for practitioners requiring more focused and in-depth information into any one particular model or numerical code. book, has clearly been extensively updated with regard to recent work and developments in the literature. Following an updating of developments in both modeling and simulation since the third edition, Chapter 1 also contains a short treatment of recent real-world operational challenges in the areas of naval operations (e.g., Unmanned Underwater Vehicles (UUV’s)), the offshore commercial sector (e.g., marine-based oil exploration) and general oceanography research. Chapter 2 contains a good summary or review of a variety of phenomena related to basic acoustical oceanography including ocean fluid properties, their relation to sound speed and propagation direction determination, the effect of sea surface and bottom boundaries, dynamic features including wind and ocean currents and internal waves and finally the impact on sound of biologics. Starting from his first edition and carrying through to this latest 2013 edition, one of Etter’s chief stated goals is to provide the reader with precise information on both the underlying assumptions behind each modeling type or method as well as describing its domain or limits of applicability. The author has been very successful in this goal, since virtually every modeling approach considered is accompanied by useful information on its specific uses, selection guidelines, shortcomings and restrictions. Most of the “meat” of the text’s coverage of underwater acoustics modeling is contained in Chapters 3–10 which together cover broad classes of modeling approaches in the important acoustical areas of propagation (Chapters 3–5), noise (Chapters 7–8), and reverberation (Chapters 9–10). In each of these three areas, the text treatment of the topic includes chapters on both the physical and then the mathematical modeling of these phenomena. Chapter 6, a new chapter added in the fourth edition, covers a wide variety of specialized modern topics and applications related to propagation including broadband modeling, nonlinear acoustics, underwater acoustic networks and vehicles, time-reversal techniques and marine mammal protection modeling efforts. The text begins with an introductory chapter offering an excellent overview of the current state of underwater acoustics modeling and simulation. This chapter, as with the remainder of this new edition Chapter 11 shifts concentration from the underwater acoustics modeling of propagation, noise and reverberation covered in the earlier chapters towards a more applied examination of the use of • www.noisenewsinternational.net • www.i-ince.org 33 these aforementioned models in the field of sonar system performance. However, unlike other navy sonar texts which delve heavily into specific sonar array designs and operation, Etter’s treatment of the topic continues to place emphasis on modeling the underwater acoustic and oceanographic environment itself and how that relates to general sonar system performance and objectives. The seemingly straightforward process of model evaluation is discussed from a variety of real-world perspectives in Chapter 12, which also contains a historical account of a number of larger-scale evaluation efforts sponsored by the US Navy and others. Finally, as mentioned, Chapter 13 is devoted solely to issues related to simulation, defined by Etter as the implementation of models over time. The brief coverage of simulation follows as a natural and logical extension from the detailed modeling concepts discussed in the earlier chapters. One of the unique strengths of Etter’s book is how comprehensively referenced it is throughout. Following the last chapter is a very impressive list of references, each individually cited in the book for a definite purpose. In addition to the reference citations included within the body of the text, an Author Index is included after the Subject index which is also convenient. Furthermore, unlike a recent trend with some other authors of later edition texts to just “tweak” the earlier edition and correct minor errata, it is clear that Etter has taken the time with this latest edition to reinvestigate the literature in each chapter’s topic and included additional upto-date information and references. Finally, a newly added Appendix D to the fourth edition includes Problem Sets for each chapter. This has likely been added in an attempt to allow use of the text in a graduate-level course setting. While the 34 number of problems included for each chapter is so far very small, it is a good start on a useful and welcome addition to the book. Overall, Paul C. Etter’s 2013 fourth edition of Underwater Acoustic Modeling and Simulation is an excellent and comprehensive introduction to an extremely broad spectrum of modeling methods and approaches in underwater acoustics and oceanography. While earlier editions of this text were already widely recognized as noteworthy and authoritative in the field, useful and meaningful updates and improvements have been made in this current edition and it is a highly recommended read.

Koch Naval Undersea Warfare Center, Newport, RI 02841-1708, USA [email protected] Acoustics of Small Rooms Mendel Kleiner and Jiri Tichy CRC Press, Taylor & Francis Group, Boca Raton, Florida, (2010), 491 pp., hardbound, 120.00 USD, ISBN 9780415779302 The acoustics of small rooms has been of interest since the dawn of recording in the late 19th century. It became a field for study for about 100 years ago after the development of broadcast radio and concerted research in the 1930s. Some seminal papers by Morse and Bolt (Rev Modern Physics, v16, 1944) and Bolt (JASA, v18, 1946) appeared after World War II and many thereafter. The term “size matters” is one that is true in acoustics, and small rooms have, when wavelengths are similar to, and greater than the dimensions of a room simple geometric and statistical analysis breaks down. Mendel Kleiner and Jiri Tichy, Professors Emeritus at Chalmers University of Technology and The Pennsylvania State University, respectively, in Acoustics of Small Rooms have produced a useful and up-to-date guide for serious students and practitioners of small room design, as well as the end-users of such rooms. There are many texts that address room acoustics, but these focus, and have an emphasis, on the acoustics of larger rooms, such as concert halls, opera houses, auditoriums and the like, and there are many texts that deal with perceptual acoustics (psychoacoustics). The concise and logical layout in Acoustics of Small Rooms allows the reader to access the information in these many tests in one place and this book presents the mathematical physics, material analysis, human factors and audio engineering, and computer and measurement techniques necessary for understanding sound fields and their perception in small rooms. The physics of small room sound fields is presented first in a chapter of the same name. In addition to the usual derivation of the wave equation for free waves and a review of acoustic metrics and analysis techniques, the authors derive the wave equation for forced waves — necessary for small rooms in which sound systems are utilized. This chapter, and others, assumes a working knowledge of calculus including complex operators. Next, the authors look at the sound fields in enclosures. Wall impedance and the boundary conditions this imposes on the eigen-function solution to wave equa tion are key to the development of modal density, modes and forced waves. In addition, the statistical parameters of the room, such as reverberation, are presented. In the chapter titled “Geometrical Acoustics”, the authors discuss transient (impulse) sounds that are produced by many sources and the hearing system’s www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September response to these sounds, ray tracing, diffraction, surface dimensions, Fresnel zones and the response (build-up and decay) of real rooms to impulses. A key design element in many rooms is absorption and the mechanisms for wall treatments which are covered next. The discussion for porous, resonators and complex absorbers is detailed with both the equations that describe the physical performance of the devices, along with many illustrations. As with some of the chapters in the text, the analysis is rigorous. Another important element in room design in general, and at times overlooked in small rooms, is diffusion of the sound field by the room boundaries — which when used correctly can be an important part of the room design. The chapter titled “Diffusion” presents a review of the basic principles of diffusors, techniques for the measurement of scattering and diffusion, design of these elements (including the effect of fins), and the absorption characteristics of diffusors. With the basics presented in the previous chapters, the next three chapters, The Ear, Psychoacoustics, and Spatial Hearing, give the reader an excellent introduction to how humans hear and how they perceive what we hear. Sometimes this aspect is overlooked in the design process. The tougher parts of small room design are covered in the next chapters. The chapter on rooms with sound systems looks at how the sound field can be analyzed in two parts to better understand the interaction between the room (which is basically 2014 September www.inceusa.org a filter) and the loudspeakers. For low frequencies loudspeaker placement and mode damping are important. For the mid-and high frequencies reflections, reverberation, absorption and diffusion are important. The text next takes a more detailed look at low-frequency sound field optimization and the difficulties in achieving same — modes, modal density and modal overlap – and two useful implementation techniques – wave modification and room geometry. Now, over the years that sound equipment and room acoustics for sound reproduction have been studied, some general characteristics for successful design have been codified. ITU-R BS.1116-1 and IEC 268-13 are two of the more common ones which specify symmetry (for stereophonic use) and the reduction of strong reflections. The near anechoic, live-end-dead-end, reflection free zone, and controlled image design protocol for control rooms are reviewed as well as suggestions for home systems. The final chapters are devoted to small room design for voice and music practice, modeling of room acoustics and measurements. For voice and music practice rooms, the design factors include the effect of instrument sound power in a small space and the risk of hearing impairment, background noise levels, similarity between the rehearsal space and the performance space, reverberation time, geometry and diffusion, and the problems when remodeling an existing space or spaces. • www.noisenewsinternational.net • www.i-ince.org The chapter on modeling discusses some physical and computer modeling techniques, and since the three models – geometrical, statistical, and wave mechanical – each cannot span the full frequency range, so especially for small rooms, the frequency range of interest is split into low and high frequency parts. The pros and cons of physical (scale), numerical models (BEM, FEM), and auralization are reviewed. The last chapter takes a look at measurement — an essential part of acoustic engineering, or as Lord Kelvin said “To measure is to know” and “If you cannot measure it, you can not improve it.” Acoustic metrics such as sound pressure, particle velocity, sound intensity measurement using a microphone or microphones, measurement sources such as loudspeakers, some of the derived metrics (distortion and noises), uncertainty (yes — there is uncertainty in audio measurements), filters, weightings, transducer noise, measurement below the Schroeder frequency, and more are discussed in this clear and concise chapter. Each chapter has a list of the references noted in the text and shows the depth of research by the authors. Acoustics of Small Rooms is a useful reference, tutorial and guide for the designer, builder and end-user of small rooms. Neil A.

Nationally, almost 60 percent of all workrelated illnesses are musculoskeletal disorders (MSDs). One in 10 of these are vibration related. In the United States alone, 2.5 million workers are exposed daily to hand-arm vibration from power tools they use on their job. These numbers are shocking! In the U.S. alone about 2.5 million workers are 40 exposed daily to Hand-Arm Vibration [HAV] from the power tools they use on their jobs. Whole Body Vibration [WBV] exposured are equally as concerning. Risks and effects of vibration on the human body in the form of whole body vibration and hand-arm vibration are well documented, and yet this is one area of occupational health and safety that many overlook. It is time for a progressive, proactive, and responsible approach to educating workers and supervisors to the the dangers of HAV and WBV and the methods of identifying, measuring, and protecting workers from unnecessary exposure.

This new preamplifier, Model 426A07, converts a high impedance signal from a measurement microphone into a low impedance signal. The preamplifier can be paired with any PCB® ¼" free-field, random incidence (diffuse field) and pressure microphone cartridges to test high frequencies ranging from the human audible range (20 Hz to 20 kHz) up to ultrasonic frequencies (greater than 100 kHz) and high amplitude measurements past the human threshold of pain (up to 194 dB).

ZweigWhite Unveils New Corporate Name and Logo ZweigWhite has introduced a new corporate name and logo that reinforces its commitment to growth through an investment in new products and services as well as delivery methods. The company has changed its name to the Zweig Group and developed a new logo that reflects its evolution as a company while offering a modern appeal. “We are bringing the mission that we were founded on into sharp focus along with a renewed commitment take this company www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014 September to the next level,” said Chad Clinehens, Zweig Group Executive Vice President. “It is important that our new name and new logo preserve those equities we built over the past 25 years, while communicating we are changing and evolving with the times and that we will be exactly what our clients need us to be. Going forward, we are going to look and feel different.” The Zweig Group’s new logo utilizes a square shape to reinforce stability and represent a uniform building block. The “Z” is made with a designer’s scale and triangle, common drafting tools used by architect and engineers. The red color is brought back from the first logo the company used when it was founded as Mark Zweig and Associates in 1988. “Our new logo is a great blend of the past and the future,” said Mark Zweig, Zweig Group CEO and Founder. “This company has gone through a lot over the past 25 years but we have stayed true to our mission. That important mission is empowering firms in the architecture, engineering, planning and environmental industry and the people that work in them to be more successful.” The re-branding campaign was launched at the firm’s annual Hot Firm and A/E Industry Awards Conference that was held in Beverly Hills last week. The announcement kicked off a complete re-branding that included the launch of a new website at www.zweiggroup.com. 2014 September www.inceusa.org The Zweig Group welcomes Randy Wilburn to the Executive Search team. Now Available: AMERICAN NATIONAL STANDARD ZweigWhite is excited to announce that Randy Wilburn is re-joining the firm to help grow the executive search division. Wilburn, who first worked for the Zweig Ghite in the firm’s executive search team in the 1990s/2000s, was an owner in the firm. Randy left the firm when it was sold in 2004 to a private equity group. Now that the Zweig Group is back in the hands of the original founding partner, Mark Zweig, Randy is re-joining the firm to help them build a key part of their business. Electroacoustics—Octave-band and Fractional-octaveband Filters—Part 1: Specifications (a Nationally Adopted International Standard) SoundPLAN #11 Released This standard provides performance requirements for analog, sampled-data, and digital implementations of bandpass filters that comprise a filter set or spectrum analyzer for acoustical measurements. It supersedes ANSI/ASA S1.11-2004 (R2009) American National Standard Specification for Octave-Band and Fractional-Octave-Band Analog and Digital Filters, and is an identical national adoption of IEC 61260:2014 Electroacoustics – Octave-band and fractional-octave-band filters, Part 1: Specifications. Significant changes from previous versions is that IEC 61260 has been adopted in full: (1) the original test methods of IEC 61260 clause 5 that was moved to an informative annex was replaced as normative, (2) the term “band number,” was replaced, and (3) some references were removed. This standard replaces ANSI/ASA S1.11-2004 (R 2009).

I can take what I’ve learned over the past decade and apply it into the AEC framework,” said Wilburn. “I am looking forward to again being a part of what I have always viewed as a great organization.” www.zweiggroup.com • www.noisenewsinternational.net • www.i-ince.org 43 Conference Calendar Acknowledgments INCE/USA Liaison Program ACO Pacific, Inc..............................................................................Belmont, California AVAC Continuing Education................................................Pittsburgh, Pennsylvania Colin Gordon and Associates...................................................San Bruno, California Acoustical Solutions......................................................................
