Acoustic Performance Metrics

Audio quality is important to network operators and end-users.  Audio performance is also important for voice-activated network services.  Certain aspects of acoustic performance can also impact on network efficiency: for example, echoes can be misinterpreted as speech, placing avoidable demands on network resources.

GCF Acoustic Performance Metrics enable device manufacturers to record standardised measurements of the device’s acoustic performance under industry agreed scenarios.

GCF’s Acoustic Performance Metrics reference 3GPP TS 26.132 which specifies test methods to assess the actual performance of a number of technical device attributes for both narrowband and wideband codecs.  Testing can also be extended beyond the device itself to include usage scenarios involving everyday accessories.
