Hearing loss combines two distinct pathologies that impair separate processing stages

Evidence

Hearing impairment is characterized by two potentially coexisting sensorineural components: (i) cochlear gain loss that yields wider auditory filters, elevated hearing thresholds and compression loss, and (ii) cochlear neuropathy, a noise-induced component of hearing loss that may impact temporal coding fidelity of supra-threshold sound. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5870
