First Claim
Patent Images
1. A method of providing neural stimulation to a recipient with a tissue-stimulating prosthesis having a plurality of channels for delivery of stimulation signals, comprising:
- receiving an input signal;
identifying the perceptual power of frequency components of the input signal;
generating stimulation signals corresponding to frequency components of said input signal;
using the perceptual power of the frequency components of the input signal to select channels for delivery to the recipient of said generated stimulation signals; and
delivering to the recipient said generated stimulation signals via said selected channels, wherein the input signal is received and said generated stimulation signals are generated prior to delivering said generated stimulation signals to the recipient.

Abstract
A tissue-stimulating prosthesis receives an input signal and determines a set of stimulation signals for use in generating electrical stimulation that will cause the recipient to perceive the input signal. The prosthesis determines a set of stimulation signals based on the perceptual power of at least one of the frequency components of the input signal or the perceptual power of one or more stimulation signals within the set.
