Patent ID: 8751006

Claim:
A method comprising: directing, by a sound processing unit, an implantable cochlear stimulator to apply a plurality of stimulation pulses each having a first pulse width by way of a plurality of electrodes during a first stimulation frame, the plurality of electrodes including a first electrode and a set of remaining electrodes; detecting, by the sound processing unit, a change in impedance of the first electrode; adjusting, by the sound processing unit in response to the change in impedance of the first electrode, a pulse width parameter associated with the first electrode to define a second pulse width that compensates for the change in impedance of the first electrode; and directing, by the sound processing unit, the implantable cochlear stimulator to apply a stimulation pulse having the second pulse width by way of the first electrode and a plurality of stimulation pulses having the first pulse width by way of the set of remaining electrodes during a second stimulation frame subsequent to the first stimulation frame.
