Two-tone suppression is a direct measure of cochlear nonlinearity

Evidence

A sensitive measure of cochlear nonlinearity is two-tone suppression, e.g., a nearly instantaneous reduction in the basilar membrane (BM) response to one tone in the presence of a second tone. — Dijk, Pim van, Physiology, Psychoacoustics and…, 921

A sensitive measure of cochlear nonlinearity is two-tone suppression, e.g., a nearly instantaneous reduction in the basilar membrane (BM) response to one tone in the presence of a second tone. There is psychoacoustic evidence that suppression measured with suppressors above the signal frequency (high-side suppression) and below the signal frequency (low-side suppression) may show different aging effects. — Dijk, Pim van, Physiology, Psychoacoustics and…, 924
