Hearing loss reduces cochlear suppression and compressive nonlinearity together

Evidence

Our Wiener-kernel approach demonstrated reduced suppression in ANF responses from HI animals, which was correlated with a loss of frequency selectivity. These HI animals also exhibited reduced magnitude DPOAEs: additional evidence of reduced compressive nonlinearity. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3878
