Patent ID: 8209025

Claim:
A system comprising: an electrode array having a plurality of electrodes disposed thereon; an implantable cochlear stimulator coupled to the electrode array and configured to apply a stimulation current to one or more locations along a cochlea of a patient via one or more of the electrodes; and a fitting station communicatively coupled to the implantable cochlear stimulator; wherein the fitting station is configured determine a plurality of narrowband spectral modulation detection thresholds and adjust the stimulation current in accordance with the narrowband spectral modulation detection thresholds; and wherein the fitting station is configured to determine the narrowband spectral modulation detection thresholds by defining a plurality of narrowband frequency ranges, applying a flat electrical stimulus within each of the frequency ranges to the patient, applying a spectrally modulated electrical stimulus within each of the frequency ranges to the patient, and modulating a spectral contrast of the spectrally modulated electrical stimuli to a smallest value at which the patient is able to distinguish between the flat electrical stimuli and the spectrally modulated electrical stimuli.
