The cochlear amplifier [PDF]

open access: yesCurrent Biology, 2004
What is it? It's the ear's built-in hearing aid. If your cochlea, the organ of hearing, did not amplify sounds the mechanical vibrations would be about hundred times too small to activate the sensory hair cells. The cochlear amplifier describes the collection of processes that increase sound vibrations in the inner ear.Why should we be interested in ...
