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. A method, comprising:
dividing an acoustic signal into first and second stimulation frames, wherein the first and second stimulation frames each include a stimulus period during which stimuli are delivered to the electrodes of the auditory prosthesis and a wait period during which no stimuli are delivered to any electrodes of the auditory prosthesis; and sequentially applying the first and second stimulation frames to the electrodes of the auditory prosthesis.
