Acoustic Testing

Acoustic Testing SLR, RLR, STMR, Distortion, Noise and Acoustic shock

Acoustic performance testing: Acoustic Performance includes tests such as Send Loudness Rating (SLR), Receive Loudness Rating (RLR), Sidetone Masking Rating (STMR), Distortion, Noise and Acoustic shock.

Voice Quality includes testing against standards such as ITU-T P.862 and ITU-T P.800.

TRaC has a test and measure solution that includes a Head and Torso Simulator (HATS) and a fully anechoic chamber so we can perform Acoustic Performance and Voice Quality assessment on your DECT, VoIP and GSM products, in addition to hands-free equipment (conference telephones), modern handsets, headsets and in-ear devices.
