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.

1. A method for generating electrical stimulation signals for stimulation contacts in an auditory implant system, the method comprising:
determining characteristic feature periods for a plurality of frequency components in an input audio signal; for a plurality of selected feature periods that meet a period selection criteria, determining adjusted feature periods that correspond to a nearest integer multiple of a language-specific fundamental period; determining a corresponding stimulation pulse rate for each adjusted feature period as a function of the nearest integer multiple of the language-specific fundamental period; assigning each stimulation pulse rate to one or more stimulation contacts; and generating the electrical stimulation signals for the stimulation contacts at their respective stimulation pulse rates.
