Optimal Model Constants For Simultaneous Stimulation With Channel Interaction Compensation

摘要

Approaches are described for fitting a simultaneous stimulation arrangement of a cochlear implant system to an implanted patient. Electrode contacts in an electrode array implanted in a patient cochlea are stimulated with a fitting pattern of stimulation signals. Then current spread decay parameters are determined for patient specific amplitude compensation of the simultaneous stimulation arrangement based on either a psychoacoustic aspect or an objective measurement of patient percept to the fitting pattern.
