For some listeners, the benefit of such technology can be accompanied by a perceived degradation in sound quality, depending on the strength of the FL setting. Purpose: The studies presented in this article investigate the effect of a new type of FL signal processing for hearing aids, adaptive nonlinear frequency compression (ANFC), on subjective speech quality. Research Design: Listener ratings of sound quality were collected for speech stimuli processed with systematically varied fitting parameters. Study Sample: Study …
