Cochlear gain loss can compensate for neural coding deficits

Evidence

The observation that HI listeners had normal AM performance despite their reduced temporal coding fidelity suggests that cochlear gain loss can compensate for temporal coding deficits to yield normal AM detection thresholds. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5872
