traveling wave theory

traveling wave theory

generally held theory that a wave travels from the base to the apex of the basilar membrane of the cochlea in response to acoustic stimulation, and that the site of maximal displacement of the basilar membrane depends on the frequency of the stimulating tone with higher frequencies causing maximal displacement near the base and lower frequencies causing maximal displacement near the apex.
