Abstract

This paper presents the performance of quality degradation indicators to be used in the context of super-wideband (50-14000 Hz) telephony. After an overview of these indicators, two analyses are undertaken: the first one considers conditions containing a single degradation and the second one considers conditions comprising several degradations at the same time, reflecting more realistic communications. This study highlights the major role of some indicators, and particularly those designed for quantifying the perceived additive noise, the frequency-response distortion and also the speech level. We show that these indicators are robust to multiple types of degradations and reveal relevant for advanced diagnosis of telecommunication systems.
