Abstract

Methods and systems for tinnitus treatment are described where a device is coupled to a surface of a bone or to a tooth or several teeth. Such a device may comprise an oral appliance having an electronic and/or transducer assembly for generating sounds via a vibrating transducer element. Generally, the transducer may be programmed to adjust any number of settings and treatment options to generate one or more frequencies of sound via the actuatable transducer to transmit a modified audio signal via vibratory conductance to an inner ear of the patient to mask the tinnitus. The audio signal is also modified to account for any hearing loss of the patient as well as a bone sensitivity threshold measured from the patient and calibrated by the programming device.

Claims

1. A method for treating tinnitus, comprising:

calibrating at least one transducer such that a tinnitus treatment audio signal is modified by a bone sensitivity threshold measured from a patient;

adjusting one or more parameters of the modified tinnitus treatment audio signal via a programming device external to the patient and in communication with at least one transducer; and

actuating the at least one transducer such that the modified tinnitus treatment audio signal is transmitted via vibratory conductance through a bone of the patient to an inner ear of the patient whereby the tinnitus is at least partially masked via the audio signal.

2. The method of claim 1 wherein calibrating comprises transmitting a test tone through the at least one transducer such that contact between the transducer and a surface of the bone is verified by the patient.

3. The method of claim 1 wherein calibrating comprises comparing the audio signal with the modified audio signal to determine which is perceived by the patient to be more natural relative to one another.

4. The method of claim 3 further comprising manually calibrating the modified audio signal via a multi-channel equalizer if the modified audio signal is perceived to be less natural relative to the audio signal.

5. The method of claim 1 wherein calibrating further comprises loudness balancing to determine the bone sensitivity threshold independent of any hearing loss of the patient.

6. The method of claim 5 wherein loudness balancing comprises transmitting an audio signal via vibratory conductance through the bone and simultaneously transmitting the audio signal via air conductance to the patient until each audio signal is matched to one another by the patient to determine the bone sensitivity threshold.

7. The method of claim 1 wherein calibrating further comprises downloading parameters of the modified audio signal from the programming device of the patient.

8. The method of claim 1 wherein adjusting comprises adjusting a period of time which the at least one transducer transmits the modified audio signal.

9. The method of claim 1 wherein adjusting further comprises adjusting the modified audio signal to compensate for a measured hearing loss of the patient prior to actuating the at least one transducer.

10. The method of claim 1 wherein adjusting comprises adjusting a pitch parameter for tinnitus of the patient.

11. The method of claim 10 wherein adjusting a pitch parameter comprises selecting one of a tinnitus pitch range of >

7 kHz, 5 to 7 kHz, 3 to 5 kHz, or <

3 kHz.

12. The method of claim 1 further comprising wirelessly transmitting the modified audio signal to the at least one transducer prior to actuating.

13. The method of claim 1 further comprising selecting between relief therapy and adaptation therapy prior to actuating.

14. The method of claim 13 wherein adjusting comprises adjusting at least one parameter of therapy dose time, adaptation level, or adaptation cycle time for adaptation therapy.

15. The method of claim 14 wherein therapy dose time ranges from 1 to 4 hours/day.

16. The method of claim 14 wherein adaptation level ranges from 5 to 20 dB.

17. The method of claim 14 wherein adaptation cycle time ranges from 1 to 10 mins.

18. The method of claim 1 wherein actuating comprises actuating the at least one transducer against a surface of at least one tooth within the patient mouth such that the modified audio signal is transmitted via vibratory conductance.

19. The method of claim 1 wherein actuating comprises actuating a piezoelectric transducer to transmit the modified audio signal via vibratory conductance through the bone.

20. The method of claim 1 further comprising overlaying the modified audio signal with an additional audio signal selected from a playlist on the programming device prior to actuating.

21. The method of claim 20 wherein the additional audio signal comprises music

22. The method of claim 20 further comprising controlling a volume of the modified audio signal independently of or simultaneously with a volume of the additional audio signal.

23. The method of claim 22 wherein simultaneously controlling a volume of the modified audio signal and a volume of the additional audio signal comprises maintaining a constant volume differential between each volume level.

24. A method for applying tinnitus adaptation therapy, comprising:

calibrating at least one transducer such that a tinnitus treatment audio signal is modified by a bone sensitivity threshold measured from a patient;

adjusting one or more parameters of the modified tinnitus treatment audio signal via a programming device external to the patient and in communication with at least one transducer;

further adjusting the modified audio signal to compensate for a measured hearing loss of the patient; and

actuating the at least one transducer such that the modified tinnitus treatment audio signal is transmitted via vibratory conductance through a bone of the patient to an inner ear of the patient whereby the tinnitus is at least partially masked via the audio signal.

25. The method of claim 24 wherein calibrating comprises transmitting a test tone through the at least one transducer such that contact between the transducer and a surface of the bone is verified by the patient.

26. The method of claim 24 wherein calibrating comprises comparing the audio signal with the modified audio signal to determine which is perceived by the patient to be more natural relative to one another.

27. The method of claim 26 further comprising manually calibrating the modified audio signal via a multi-channel equalizer if the modified audio signal is perceived to be less natural relative to the audio signal.

28. The method of claim 24 wherein calibrating further comprises downloading parameters of the modified audio signal from the programming device of the patient.

29. The method of claim 24 wherein adjusting comprises adjusting a period of time which the at least one transducer transmits the modified audio signal.

30. The method of claim 24 wherein adjusting comprises adjusting a pitch parameter for tinnitus of the patient.

31. The method of claim 30 wherein adjusting a pitch parameter comprises selecting one of a tinnitus pitch range of >

7 kHz, 5 to 7 kHz, 3 to 5 kHz, or <

3 kHz.

32. The method of claim 24 further comprising wirelessly transmitting the modified audio signal to the at least one transducer prior to actuating.

33. The method of claim 24 further comprising selecting between relief therapy and adaptation therapy prior to actuating.

34. The method of claim 33 wherein adjusting comprises adjusting at least one parameter of therapy dose time, adaptation level, or adaptation cycle time for adaptation therapy.

35. The method of claim 24 wherein actuating comprises actuating the at least one transducer against a surface of at least one tooth within the patient mouth such that the modified audio signal is transmitted via vibratory conductance.

36. The method of claim 24 wherein actuating comprises actuating a piezoelectric transducer to transmit the modified audio signal via vibratory conductance through the bone.

37. The method of claim 24 further comprising overlaying the modified audio signal with a song selected from a playlist on the programming device prior to actuating.
