Restoring audibility does not restore sound localization in hearing loss

Evidence

Hearing impairment alters sound localization abilities for many listeners, although there is considerable variability in performance. Some listeners have near-normal sound localization abilities, but many listeners experience deficits. Restoring audibility does not correct these sound localization problems, as the deficits are likely due to changes in neural coding. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1600

Categorization

• QUESTION: What specific neural coding changes underlie the localization deficits untouchable by audibility restoration? This suggests central auditory processing damage distinct from peripheral sensitivity loss.
• DEFINE: Defines precedence effect and its role with binaural unmasking.
• corroborated: 2 independent passages support this claim — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1600
