Abstract
Approaches are described for fitting an implanted cochlear implant having electrode array contacts to an implanted patient. For multiple different fitting methods, each fitting method is assigned one or more electrode contacts wherein no electrode contact is assigned more than one fitting method. For each fitting method, the assigned electrode contacts are fitted according to the fitting method and fitting values for non-assigned electrode contacts are interpolated. Then a fitting is performed for each electrode contact in the electrode array based on a weighted averaging of the fittings for the various different fitting methods.

- ii. interpolate fitting values for all of the remaining electrode contacts based on the fitting of the electrode contacts assigned to the fitting response measurement;
- and
- means for fitting each of the plurality of electrode contacts based on a weighted averaging of the fittings for the plurality of different fitting response measurement methods.
