AUDITORY PROSTHESIS STIMULATION RATE AS A MULTIPLE OF INTRINSIC OSCILLATION

摘要

A method is described for generating electrical stimulation signals for stimulation contacts in an auditory implant system. Characteristic feature periods are determined for frequency components in an input audio signal. For selected feature periods that meet a period selection criteria, adjusted feature periods are determined that correspond to a nearest integer multiple of a language-specific fundamental period. A corresponding stimulation rate frequency is determined for each adjusted feature period, and each stimulation rate frequency is assigned to one or more stimulation contacts. The stimulation signals are then generated for the stimulation contacts at their respective stimulation rate frequencies.
