Fiber-type-specific damage produces distinct loudness perception abnormalities.

Evidence

An implication of this work, then, is that damage to any of the various types of auditory nerve fibers should alter the perception of loudness. Although we currently have no mechanism to assess the health of various fiber types, damage to the low-threshold fibers will impact threshold measurements and loudness near threshold. Abnormal loudness perception of high-level sounds might implicate loss or damage to highand mid-threshold fibers. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 737
