Auditory signal processing

摘要

Methods, systems, and devices for processing an auditory signal to generate auditory prosthesis electrode stimuli in response to an incoming acoustic signal are disclosed. An example method includes dividing the incoming acoustic signal into one or more frequency envelopes. The example method also includes determining which auditory prosthesis electrodes to stimulate. The example method additionally includes determining a temporal reference point to which auditory prosthesis electrode stimuli are referenced. The example method further includes determining a delay for each of the auditory prosthesis electrode stimuli from the temporal reference point. The example method yet further includes determining amplitudes of the auditory prosthesis electrode stimuli. The example method also includes determining a wait period length before each successive temporal reference point.

1. An auditory signal processing method, the method comprising:
dividing an acoustic signal into one or more frequency envelopes; determining which electrodes of an auditory prosthesis to stimulate; determining a temporal reference point for stimulating the determined electrodes; determining, for each of the determined electrodes, a respective delay from the determined temporal reference point, wherein the respective delay defines how long to wait after the determined temporal reference point before stimulating the respective electrode; determining, for each of the determined electrodes, a respective amplitude based on an amplitude of one of the one or more frequency envelopes; and stimulating the determined electrodes of the auditory prosthesis by applying stimulus to each electrode with the electrode's determined delay and amplitude.
