Two-tone suppression is an instantaneous reduction of basilar membrane response

Evidence

Previous studies have examined the relationship between ANF 2TS and chronic low-level noise exposure coupled with ageing in the Mongolian gerbil (Schmiedt et al. 1990 ; Schmiedt and Schultz 1992 ), and following an acute intense noise exposure in the cat (Miller et al. 1997 ). Ageing in a noisy environment was associated with a loss of 2TS. Schmiedt and colleagues often found complete absence of high-side 2TS, with sparing of low-side 2TS, even in cochlear regions with up to 60 % outer-hair-cell loss; suggesting potentially different mechanisms for lowand high-side suppression. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3876 (#expands, via linked claim)
