Multirate cochlear stimulation strategy and apparatus

摘要

A cochlear implant system in which information about the periodicity of a received audio signal in each filter channel is used as a factor in determining the rate of stimulation applied to a tonotopically placed electrode corresponding to the relevant filter channel. As such, the stimulation rate for each electrode is related to the periodicity of the signal in the filter channel corresponding to that electrode. This may allow for improved perception of pitch by the implant recipient.
