Optimizing pitch allocation in a cochlear implant
First Claim
1. A fitting tool for adjusting a cochlear implant system, the fitting tool comprising:
- a software program interface to present variations of a musical melody comprising frequencies to a user through a multi-electrode array, wherein particular frequencies are associated with particular electrodes;
wherein the fitting tool enables the user to select at the interface a variation of the musical melody, and wherein the cochlear implant system is adjusted by using the selected variation to modify the frequencies associated with the electrodes.

Abstract
Errors in pitch allocation within a cochlear implant are corrected in order to provide a significant and profound improvement in the quality of sound perceived by the cochlear implant user. The disclosure provides a tool for determining the implant fitting curve for cochlear implant system to correct pitch warping. The method presents familiar musical tunes to determine the implant fitting slope (relative alignment). In addition, in one embodiment, speech sounds may be used to determine the offset of the fitting line (absolute alignment). The use of music and speech to determine the implant fitting curve (line) and the slope is facilitated by using techniques to implement virtual electrodes to more precisely direct stimuli to the location or “place” on the cochlea.
