HQS-Ac2Ac (Code 60025)
HQS-Ac2Ac allows to test arbitrary voice communication systems from a purely acoustic end-to-end viewpoint. It is ideally suited for testing speech transmission quality of inaccessible transmission paths, e.g. due to encryption, proprietary codecs or location-bound endpoints. The test suite covers basic and advanced performance metrics in voice communication, e.g. echo, double-talk, interfering background noise and more.
HQS-ANC-Car (Code 60066)
HQS-ANC-Car is a test suite for integrated and stand-alone active noise cancellation (ANC) systems in vehicles. The test suite contains tests regarding ambient noise reduction, listening effort improvement of external speech, and a self-noise assessment of the ANC system.
HQS-ViBRIDGE (Code 60067)
HQS-ViBRIDGE allows optimizing and analyzing the performance of earbuds which are equipped with bone conduction sensors. The quality standard contains multiple test cases for measuring the speech quality in the uplink for different scenarios, e.g. with interfering background noise, in double-talk situations and in the presence of a near-end concurrent talker.
