Optimizing pitch allocation in a cochlear stimulation system
First Claim
1. A method of fitting a user'"'"'s cochlear implant system using a computerized fitting system, wherein the cochlear implant system includes an electrode array having a plurality of electrodes implanted into a cochlea of a user, the method comprising:
- presenting from the computerized fitting system a plurality of sounds to the user through the electrode array, wherein each sound comprises a plurality of notes;
receiving from the user at the computerized fitting system a selection of one of the plurality of sounds that most closely conforms to a single note; and
determining at the computerized fitting system how to tune the cochlear implant system based on the received selection.

Abstract
Optimizing pitch allocation in a cochlear stimulation system may include implanting an electrode array having a plurality of electrodes into the cochlea of a patient, where the electrode array has an associated implant fitting characteristic that defines a relationship between the implanted electrode array and audio frequencies, presenting sounds through the electrode array to the patient, receiving from the patient a selection of one of the sounds that most closely conforms to a single note, and determining a slope of the implant fitting characteristic of the electrode array based on the sound selected by the patient. Each sound may include a fundamental frequency and one or more harmonics. The optimization may also include changing a center frequency of a band pass filter associated with each electrode based on the determined slope.

10. A method of fitting a user'"'"'s cochlear implant system using a computerized fitting system, wherein the cochlear implant system includes an electrode array having a plurality of electrodes implanted into a cochlea of a user, the method comprising:
-
presenting from the computerized fitting system a first tone to the user through the electrode array, wherein the first tone comprises a first frequency and a second frequency; presenting from the computerized fitting system a second tone to the user through the electrode array, wherein the second tone comprises the first frequency but not the second frequency; if the second tone does not sound like the first tone to the user, adjusting in the computerized fitting system the second frequency by an offset until the second tone sounds like the first tone to the user; and determining in the computerized fitting system how to tune the cochlear implant system using the offset. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

29. A method of fitting a user'"'"'s cochlear implant system using a computerized fitting system, wherein the cochlear implant system includes an electrode array having a plurality of electrodes implanted into a cochlea of a user, wherein each electrode receives signals within a frequency band, the method comprising:
-
presenting from the computerized fitting system a first tone to the user through the electrode array comprising a first frequency and a second frequency, wherein the first frequency is within a first frequency band and wherein the second frequency is within a second frequency band; adjusting in the computerized fitting system the second frequency in the first tone by a first offset until the first tone sounds like a single note to the user; and determining in the a computerized fitting system how to tune the second frequency band in the cochlear implant system using the first offset. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
