Auditory nerve damage degrades sound localization by corrupting ILD and ITD cues
Evidence
Regarding temporal coding, Ruggero, Rich, and Recio (1992) noted small shifts in the delay of the traveling wave after cochlear death, and Heinz, Swaminathan, Boley, and Kale (2010) have demonstrated that cochlear damage can also distort the across-frequency representation of temporal fine structure in auditory nerve fibers. Such temporal distortions would not need to be large to disrupt the fine temporal synchronization necessary for representation by the MSO. … Alterations in the amount of basilar membrane vibration with level (Ruggero & Rich, 1991) also will yield abnormal excitation and inhibition within the LSO. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1584 (
