EQUEST injects temporal masking knowledge into echo annoyance estimation

Evidence

Another application for the same task is the echo quality evaluation of speech in telecommunications test (EQUEST), which is an instrumental method for estimating the annoyance (EQUEST, 2012). EQUEST is, again, a relatively complex signal processing algorithm, which uses psychoacoustic knowledge to perform the evaluation. This time the knowledge of the psychoacoustic temporal masking characteristics of human listeners is injected into the algorithm to estimate the annoyance caused by echoes. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2461
