  New GSMA Standard „HD Voice“
HEAD Press Release Herzogenrath, October 31, 2012
New GSMA Standard „HD Voice“
Standardization bodies, network providers, chip developers, device manufacturers are currently all pushing into one direction: wideband telephony.
So it is no surprise that the GSM Association (GSMA) has specified test methods to assess the minimum performance requirements for allowing manufacturers of mobile devices to make use of the HD Voice Logo which has been registered as trademark by GSMA.
Logo HD Voice
HEAD acoustics actively contributed to the development of this standard and has implemented all speech quality measurements required by GSMA HD Voice Annex C2 into the automated test suite “GSMA HD Voice” for the communication quality analysis system ACQUA.
“GSMA HD Voice” thus allows manufacturers to ensure that their mobile devices meet the specifications required for using the HD Voice logo.
The tests implemented in the GSMA HD Voice test suite cover all acoustic performance aspects concerning mobile devices (handset, handheld hands-free, headset), both for narrowband and wideband scenarios, as specified by the GSMA HD Voice standard.
For the determination of background noise transmission quality, a standardized arrangement consisting of four loudspeakers and one subwoofer is used in a separate test room setup. It allows a close-to-reality noise playback and can be used for all types of background noise.
In conjunction with the analysis system ACQUA, the analysis option ACOPT 21 (3QUEST according to EG 202396-3), the measurement standard TS 26131_32 as well as the measurement front end MFE VI.1 with BEQ option and other components, the GSMA HD Voice test suite allows the fast and easy acquisition, analysis and documentation of measurement data.
