1. A method for mapping cochlear locations to audio frequencies, the method comprising:
- applying a first signal and a second signal to locations within a user'"'"'s cochlea through a multi-electrode array implanted into the user'"'"'s cochlea, wherein particular frequencies are associated with particular electrodes;
shifting the location where the first signal is applied to cause the user to perceive tonal variations of the first signal;
allowing the user to select one of the tonal variations;
shifting the pitch of both the second signal and the selected tonal variation of the first signal;
allowing the user to select one of the pitch-shifted versions of both the second signal and the selected tonal variation of the first signal; and
modifying the frequencies associated with the electrodes using the selected pitch-shifted version.

Abstract
Systems for fitting an implantable cochlear stimulator to a patient include an interface unit configured to display a graphical representation of an implant fitting line as part of a graphical user interface. The implant fitting line has a slope and a horizontal position and represents a mapping relationship between a plurality of audio frequencies and a plurality of stimulation sites within a cochlea of the patient. The interface unit is further configured to facilitate adjustment of the slope and/or horizontal position of the fitting line.

8. A method for mapping cochlear locations to audio frequencies, the method comprising:
-
(a) applying a first signal and a second signal to locations within a user'"'"'s cochlea through a multi-electrode array implanted into the user'"'"'s cochlea, wherein particular frequencies are associated with particular electrodes; (b) shifting the location where the first or second signals are applied to vary the tone between the first and second signals; (c) shifting the pitch of both the first and second signals; (d) allowing the user to select a shifted location and a shifted pitch from steps (b) and (c); and (e) modifying the frequencies associated with the electrodes using the selected shifted location and the selected shifted pitch. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
