Sensorineural hearing loss disrupts auditory-nerve phase-locking to modulated stimuli

Evidence

The Zilany et al. ( 2014 ) model for AN responses has a provision for including impairment due to outer and inner hair cell dysfunction (Zilany and Bruce 2007 ), which reduces synchrony capture in a manner comparable to that observed in acoustically traumatized ears (Miller et al. 1997 ). Here SNHL was simulated by setting AN model parameters COHC and CIHC to 0.3; these values simulate mild hearing loss, with threshold elevations ranging from about 15 dB at 500 Hz to 30 dB at 2000 Hz and higher. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5479

• DEFINE: Clarifies that COHC and CIHC model parameters simulate outer and inner hair cell dysfunction, with specific threshold-elevation values.
