Arrival of a traveling wave causes the basilar membrane to move up and down, bending the stereocilia against the tectorial membrane. This depolarizes the hair cells, leading to transmitter release on the afferent neurons that course into the auditory nerve.
Whichever ear receives the loudest stimulus can also shut off activity in the ascending pathway from the less stimulated ear
The players here are the lateral superior olive (LSO) and the medial superior nucleus of the trapezoidal body (MNTB).

A key component of the normal function of this area is analysis of the time sequence of sounds. Most commonly, during early postnatal development the left cortex acquires dominance for spoken language processing. The right cortex then is free to differentiate a specialization in processing musical language.
