Patent ID: 8798758

Claim:
A system for activating electrodes, the system including: a multi-channel electrode array; a stimulator for activating electrodes in the electrode array using channel specific sampling sequences; a signal processor including a filter bank for receiving an acoustic representative electrical signal, each filter in the bank of filters associated with one of the electrodes in the multi-channel electrode array, each electrode in the multi-channel electrode array associated with a different channel specific sampling sequence, wherein the channel specific sampling sequence has a predefined duration, amplitude, plurality of pulses and pulse rate, the duration and number of pulses in each channel specific sampling sequence derived from the center frequency of the associated band pass filter, and wherein a weighting factor is applied to each channel specific sampling sequence so as to create a weighted channel specific sampling sequence for each electrode in the electrode array, the weighting factor based, at least in part, on an acoustic representative electrical signal.
