TS 102 924/925
(Code 60035)
Superwideband/Fullband
Speech Quality
Overview
TS 102 924/925 contains measurements from “ETSI Speech and multimedia
Transmission Quality (STQ); Transmission requirements for Superwideband/
Fullband handsfree and conferencing/
headset terminals from a QoS perspective
as perceived by the user” which specifies
test methods to assess minimum performance requirements for Superwideband
and Fullband terminals.
HEAD acoustics has implemented these
test methods into the automated test suite
TS 102 924/925 for the communication
quality analysis system ACQUA.

DESCRIPTION
APPLICATIONS
The tests implemented in the TS 102
924/925 test suite cover basic electro-acoustic performance aspects of
Superwideband/Fullband hands-free and
headset terminals as defined and required
by ETSI in the documents “ETSI TS 102
924/925” from October 2014.
These tests cover requirements for handsfree and headset configurations.
The measurements in the HEAD acoustics
test suite may be changed, adapted or
modified if needed in order to conduct additional tests. The tests can be combined in
any way to create individual test sequences.
Combined with the advanced communication quality analysis system ACQUA, the
measurement front ends MFE VI.1 and MFE
VIII.1 as well as other components, the TS
102 924/925 test suite with its predefined
measurement descriptors and automated
measurement sequences allows the fast
and easy acquisition, analysis and documentation of measurement data.
•Conformance testing of Superwideband and Fullband hands-free and
headset terminals according to “TS
102 924/925” by ETSI
•Automated quality analysis of Superwideband and Fullband hands-free
and headset terminals
•Experimental development and optimization of Superwideband and Fullband
hands-free and headset terminals with
objective evaluation of speech quality
(requires ACOPT 30 POLQA)
