a cochlear implant processing strategy increases speech clarity and higher temporal performance . the strategy determines the power spectral component within each channel , and dynamically selects or de - selects the channels through which a stimulation pulse is provided as a function of whether the spectral power of the channel is high or low . “ high ” and “ low ” are estimated relative to a selected spectral power , for example . the selected spectral power can be estimated by signal average or mean , or by other criteria . once a selection of the channels to stimulate has been made , the system can decide that only those channels are stimulated , and stimulation is removed from the other channels . the selected channels are the ones on which the spectral power is above the mean of all the available channels . fewer channels are stimulated at any time and the contrast of the stimulation is enhanced . also , the temporal resolution increases as the number of channels that must be stimulated on a given frame decreases . this way , the channels which are presented to the patient are fewer in number and contain more temporal information .
