IMPLANTABLE HEARING AID UTILIZING A STIMULATION PULSE

A hearing aid implant includes a control unit and a stimulation unit. The control unit is configured to generate a train of biphasic electric pulses with each biphasic electric pulse comprising a stimulation pulse and a charge-compensation pulse, and to adjust a current stimulation rate to generate an adjusted stimulation rate and at least one of pulse amplitude or pulse duration of the stimulation pulse. The implant also includes a stimulation unit configured to deliver said train of electric pulses to an electrode array that is configured to provide electric stimulation according to the stimulation rate and adjusted stimulation rate. The control unit is further configured to calculate a pulse amplitude and pulse duration of the charge-compensation pulse corresponding to the stimulation pulse such that the charge-compensation pulse has the pulse amplitude and pulse duration that charge compensates the charge caused by the stimulation pulse, and the pulse duration is according to the stimulation rate and adjusted stimulation rate.
