Abstract

An audio prostheses having a set of operating parameters is fit to an implanted patient. An audio stimulation pattern is initiated to the audio prosthesis. A fit adjustment process is performed during the audio stimulation pattern, which includes: changing a set of selected operating parameter values. Patient feedback is received that indicates a subjective performance evaluation of operation of the audio prosthesis. The process is repeated (e.g., continuously) to collect performance evaluation data related to the operating parameter values. Then the operating parameters are set based on the performance evaluation data.

Claims

1. A method of fitting to a patient an audio prosthesis having a set of operating parameters, the method comprising:

initiating an audio stimulation pattern to the audio prosthesis;

performing a fit adjustment process during the audio stimulation pattern, the process including;

i. continuously changing a set of selected operating parameter values of the audio prosthesis, wherein the operating parameter values are changed sequentially and/or simultaneously

ii. continuously receiving patient feedback indicating a subjective performance evaluation of operation of the audio prosthesis, and

iii. repeating the process to collect performance evaluation data related to the operating parameter values; and

setting the operating parameter values based on the performance evaluation data.

2. A method according to claim 1, wherein the operating parameter values are changed by the patient.

3. A method according to claim 1, wherein the operating parameter values are changed by fit adjustment software.

4. A method according to claim 3, wherein the operating parameter values are changed based on a Levenberg Marquardt Algorithm.

5. A method according to claim 1, wherein the subjective performance evaluation is based on a comparison to operation of the audio prosthesis according to a set of reference operating parameter values.

6. A method according to claim 1, wherein the audio prosthesis is a cochlear implant.

7. A method according to claim 1, wherein the audio prosthesis is a digitally programmed hearing aid.

8. A method according to claim 1, wherein the audio prosthesis is a hybrid acoustic-electrical stimulation system.

9. A system for fitting to a patient an audio prosthesis having a set of operating parameters, the system comprising:

means for initiating an audio stimulation pattern to the audio prosthesis;

means for performing a fit adjustment process during the audio stimulation pattern, the process including;

i. continuously changing a set of selected operating parameter values of the audio prosthesis, wherein the operating parameter values are changed sequentially and/or simultaneously

ii. continuously receiving patient feedback indicating a subjective performance evaluation of operation of the audio prosthesis, and

iii. repeating the process to collect performance evaluation data related to the operating parameter values; and

means for setting the operating parameter values based on the performance evaluation data.

10. A system according to claim 9, wherein the operating parameter values are changed by the patient.

11. A system according to claim 9, wherein the operating parameter values are changed by fit adjustment software.

12. A system according to claim 11, wherein the operating parameter values are changed based on a Levenberg Marquardt Algorithm.

13. A system according to claim 9, wherein the subjective performance evaluation is based on a comparison to operation of the audio prosthesis according to a set of reference operating parameter values.
