MOCR gain reduction interacts with suppression to reduce it

Evidence

When suppression is measured with combined maskers long enough to elicit MOCR-induced gain reduction, suppression may be underestimated. However, even when measured with the shorter combined maskers, older adults had less suppression than younger adults. Evidence from animal studies suggests that gain reduction from the MOCR and suppression interact, resulting in decreased suppression (Winslow and Sachs 1987 ; Kawase et al. 1993 ). The results of the present study support this idea. — Dijk, Pim van, Physiology, Psychoacoustics and…, 921
