Abstract
An exemplary sound processor (104) may 1) identify a stimulation site within a cochlea of a patient that is to be stimulated in order to represent an audio signal presented to the patient, 2) dynamically designate, based on the identified stimulation site, a first group of one or more electrodes as a group of one or more main electrodes and a second group of one or more electrodes as a group of one or more compensating electrodes and 3) dynamically determine, based on the identified stimulation site, an amount of main current to be applied to each electrode included in the first group of one or more electrodes in order to represent the audio signal and an amount of compensating current to be applied to each electrode included in the second group of one or more electrodes to focus an excitation field created by the main current.
