Abstract

Approaches are described for fitting an implanted cochlear implant having electrode array contacts to the implanted patient. A normal electrode stimulation arrangement is used to deliver electrode stimulation signals to the active electrode channel electrode contacts at an initial common charge level. The common charge level is increased until a desired common percept criteria is met to establish a common baseline charge level for the stimulation electrode contacts. For each individual electrode contact, a fitting stimulation signal is delivered to the electrode starting from the common baseline charge level and the charge level is increased until an individual electrode percept criteria is met.
