1. A method for determining a cochlear implant frequency map that correlates audio frequencies to cochlear locations, the method comprising:

  • applying a first signal of a first frequency and a second signal of a second frequency 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 and wherein the first signal has a known harmonic relationship with the second signal;

    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 that the user perceives as best conforming to the known harmonic relationship; and

    determining the frequency map at least in part by using the selected tonal variation to modify the frequencies associated with the electrodes.
