Input Selection For An Auditory Prosthesis

摘要

Providing stimulation signals for an implanted auditory prosthesis including receiving first and second sound signals at first and second sound input devices, each of the first and second signals having a signal-to-noise ratio; determining a signal parameter related to said signal-to-noise ratio of each of the first and second signals; selecting one of the first and second signals which has the greater signal-to-noise ratio; and generating stimulation signals for the implanted auditory prosthesis based on said selected sound signal.

1. A method for generating stimulation signals in an auditory prosthesis system comprising:
receiving a first sound signal at a first sound input device; receiving a second sound signal at a second sound input device; determining a first estimated signal-to-noise ratio (SNR) of the first sound signal; determining a second estimated SNR in the second sound signal; comparing the first SNR to the second SNR to select a sound signal from one of the first sound signal or the second sound signal that has the highest SNR; and based on at least the selected sound signal, generating stimulation signals capable of causing a hearing percept.
