Quiet-versus-narrowband-masked AM threshold differences can isolate temporal coding from cochlear compression
Evidence
AM thresholds to pure-tone carriers (4 kHz) in normal-hearing listeners depended on temporal coding fidelity. AM thresholds in hearing-impaired listeners were normal, indicating that reduced cochlear gain may counteract how reduced temporal coding fidelity degrades AM thresholds. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5870 (
