TOP-VALUE-DERIVED TIME CONTROL STIMULATION STRATEGY FOR A MULTI-CHANNEL COCHLEAR IMPLANT

摘要

A cochlear binary implant system having two intracochlear implants for implantation in the snails of a user, each cochlear implant employing a speech processing strategy in which the electrical stimuli are adjusted to the relative timing of the relevant audio signals as detected by each ear, such that the interaural time delays between the audio signals at each ear are substantially retained in electrical stimuli at each ear. The processing strategy includes bandpass filtering the audio signal, detecting the peaks in and the intensity of each band, prioritizing and placing each peak in a buffer in time slots according to the relative timing of each peak. The buffer output forms the basis for the stimulus instructions.
