Hearing loss disrupts pitch perception through multiple independent coding failures

Evidence

Regardless, we see that pitch perception in listeners with hearing loss can be disrupted in a variety of ways. Disruptions to the place code can occur because of poor frequency selectivity or an altered representation of the place of maximal stimulation on the basilar membrane. Distortions to the temporal code may also contribute to poor perception of pitch by listeners with hearing loss. Asymmetries in pitch representations across the ears can also be problematic, leading to diplacusis, and sloping or rising hearing loss could cause the pitch code to be contradictory at high versus low frequencies. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1337
