Abstract

A method of tuning a hearing device includes sending a test signal to a model of a hearing device that may be remote from the actual hearing device being tuned. The test signal is encoded by the model and sent to the hearing device being tuned. The user of that hearing device sends a response signal based at least in part on the encoded test signal. This response is received and compared to the original test signal. Thereafter, an operational parameter is sent to the hearing device based on the comparison.

First claim

What is claimed is:

1. A system for tuning a hearing device, the system comprising:
a first transmitter for sending a test signal to a model of the hearing device;
an encoder for encoding the test signal using the model of the hearing device, wherein the model identifies a type of the hearing device being tested;
a processor for setting a parameter of the model, wherein the parameter is based at least on a measured response;
a second transmitter for sending the encoded test signal to the hearing device associated with a user;
a receiver for receiving a user response, wherein the user response is provided in response to the encoded signal; and
a comparison module for comparing the user response to the test signal.

2. The system of claim 1 , further comprising a test set generator for generating a test signal.

3. The system of claim 2 , wherein the test set generator and the comparison module are located remote from the hearing device.

4. The system of claim 3 , wherein the signal encoder and the model of the hearing device are located remote from the hearing device.

5. The system of claim 1 , further comprising an adjustment module for selecting an operational parameter of the hearing device based at least on a comparison of the user response and the test signal.

6. The system of claim 5 , wherein the second transmitter transmits the operational parameter to the hearing device.

7. The system of claim 5 , wherein the encoded test signal comprises at least one distinctive feature of speech.

8. The system of claim 7 , wherein the at least one distinctive feature of speech comprises at least one of a fundamental source feature, a secondary consonantal source feature, and a resonance feature.

9. The system of claim 7 , further comprising an association module for associating the operational parameter of the hearing device with the at least one distinctive feature of speech.

10. The system of claim 1 , wherein the encoded test signal is sent over a network.

11. A digital hearing device comprising the system of claim 1 .

12. A method of tuning a hearing device, the method comprising the steps of:
sending a test signal to a model of the hearing device;
encoding the test signal using the model of the hearing device, wherein the model identifies a type of the hearing device being tested;
sending the encoded test signal to the hearing device associated with a user;
receiving a user response to the encoded test signal;
comparing the user response with the test signal; and
sending at least one operational parameter to the hearing device based at least on the comparison.

13. The method of claim 12 , further comprising the step of selecting a test signal.

14. The method of claim 12 , wherein the test signal comprises at least one feature of speech.

15. The method of claim 14 , wherein the encoding step comprises digitizing the at least one feature of speech.

16. The method of claim 14 , wherein the encoding step comprises adjusting a characteristic of the feature of speech.

17. The method of claim 16 , wherein the characteristic of the feature of speech comprises at least one of a fundamental source feature, a secondary consonantal source feature, and a resonance feature.

18. The method of claim 12 , wherein the test signal comprises an electrical signal corresponding to a stimuli comprising at least one feature of speech.

19. The method of claim 16 , further comprising the step of associating the operational parameter of the hearing device with the at least one feature of speech.

20. The method of claim 12 , wherein the encoded test signal is sent over a network.

21. The method of claim 20 , wherein the network is TCP/IP enabled.

22. The method of claim 12 , wherein the model of the hearing device is located remote from the hearing device.

23. The method of claim 12 , wherein the model of the hearing device is collocated with the hearing device.

24. The method of claim 14 , further comprising the step of receiving at the hearing device the encoded test signal and processing the encoded test signal.

25. The method of claim 24 , wherein the processing step comprises reproducing the at least one feature of speech.

26. An article of manufacture comprising computer-readable program instructions that, when executed by at least one processor, perform a method for tuning a hearing device, the method comprising:
sending a test signal to a model of the hearing device;
encoding the test signal using the model of the hearing device, wherein the model identifies a type of the hearing device being tested;
sending the encoded test signal to the hearing device associated with a user;
receiving a user response to the encoded test signal;
comparing the user response with the test signal; and
sending at least one operational parameter to the hearing device based at least on the comparison.
