HASQI
HASQI, ''Hearing-Aid Speech Quality Index'', is a measure of audio quality originally designed for the evaluation of speech quality for those with a hearing aid,. It has also been shown to be able to gauge audio quality for non-speech sounds and for listeners without a hearing loss.
== Background ==
While the perception of audio quality can be gauged through perceptual measurements, the testing is time-consuming to undertake. Consequently, a number of metrics have been developed to allow audio quality to be evaluated without the need for human listening. Standardized examples from telephony include PESQ, POLQA, PEVQ and PEAQ. HASQI was originally developed by Kates and Arehart to evaluate how the distortions introduced by hearing aids degrade quality.〔 They also produced a new version in 2014.〔
Kressner et al.〔 tested a speech corpus different from the dataset used to develop HASQI and showed that the index generalizes well for listeners without a hearing loss with a performance comparable to PESQ. Kendrick et al. showed that HASQI can grade the audio quality of music and geophonic, biophonic, and anthrophonic quotidian sounds, although their study used a more limited set of degradations.
