Patent ID: 8422706

Claim:
A method of reducing an effect of ambient noise within an auditory prosthesis system, the method comprising: dividing, by a sound processing subsystem, an audio signal presented to an auditory prosthesis patient into a plurality of analysis channels each containing a frequency domain signal representative of a distinct frequency portion of the audio signal; determining, by the sound processing subsystem, a noise reduction gain parameter for each of the frequency domain signals based on a signal-to-noise ratio of each of the frequency domain signals; applying, by the sound processing subsystem, noise reduction to the frequency domain signals in accordance with the determined noise reduction gain parameters to generate a noise reduced frequency domain signal corresponding to each of the analysis channels; and generating, by the sound processing subsystem, one or more stimulation parameters based on the noise reduced frequency domain signals and in accordance with at least one of a current steering stimulation strategy and an N-of-M stimulation strategy.
