Abstract

Disclosed herein, among other things, are systems and methods for detection of special environments for hearing assistance devices. One aspect of the present subject matter includes a method of operating a hearing assistance device for a user. A signal is received from a mobile device, such as a cellular telephone, representative of an environmental parameter sensed by the mobile device. In various embodiments, an acoustic environment about the mobile device is identified based on the received signal using a signal processor. An operational mode of the hearing assistance device is adjusted using the signal processor based on the identified acoustic environment, according to various embodiments.

Claims

1. A method of operating a hearing assistance device worn on or about an ear of a user, the method comprising:

receiving a signal from a cellular telephone representative of a parameter sensed by the cellular telephone, wherein the parameter includes combined information relating to location of the cellular telephone and acceleration of the cellular telephone;

identifying an acoustic environment about the hearing assistance device based on the received signal from the cellular telephone in combination with audio information from the hearing assistance device using a signal processor and without using an output from an accelerometer in the hearing assistance device for identifying the acoustic environment; and

adjusting an operational mode of the hearing assistance device using the signal processor based on the identified acoustic environment.

2. The method of claim 1, wherein identifying an acoustic environment includes identifying an inside of a moving vehicle.

3. The method of claim 2, wherein identifying an acoustic environment includes identifying an inside of a moving automobile.

4. The method of claim 2, wherein receiving a signal from a cellular telephone representative of an environmental parameter includes receiving a signal sensed by an accelerometer in the cellular telephone that movement at greater than 5 mph is detected to identify the moving vehicle.

5. The method of claim 1, wherein receiving a signal from a cellular telephone representative of an environmental parameter includes receiving a signal from global positioning system (GPS) in the cellular telephone.

6. The method of claim 3, wherein adjusting an operational mode of the hearing assistance device includes switching to an omni-directional microphone mode.

7. The method of claim 1, wherein identifying the acoustic environment includes using acoustic inputs in combination with the received signal from the cellular telephone.

8. The method of claim 7, wherein receiving the signal includes receiving a Bluetooth™

signal from the cellular telephone.

9. The method of claim 7, wherein receiving the signal includes receiving a CDMA cellular protocol signal from the cellular telephone.

10. The method of claim 7, wherein receiving the signal includes receiving a GSM cellular protocol signal from the cellular telephone.

11. A hearing assistance system including a hearing assistance device worn on or about an ear of a user, the system comprising:

a wireless receiver configured to receive a signal from a cellular telephone including a representation of a sensed parameter related to an acoustic environment about the hearing assistance device, wherein the environmental parameter includes combined information relating to location of the cellular telephone and acceleration of the cellular telephone; and

a processor configured to identify the acoustic environment using the received signal from the cellular telephone in combination with audio information from the hearing assistance device without using an output from an accelerometer in the hearing assistance device for identifying the acoustic environment, and to adjust a hearing assistance device parameter based the identified environment.

12. The system of claim 11, wherein the sensed parameter includes a parameter sensed by a global positioning system (GPS).

13. The system of claim 11, wherein the sensed parameter includes a parameter sensed by an accelerometer.

14. The system of claim 11, wherein the hearing assistance device includes a hearing aid.

15. The system of claim 14, wherein the hearing aid includes an in-the-ear (ITE) hearing aid.

16. The system of claim 14, wherein the hearing aid includes a behind-the-ear (BTE) hearing aid.

17. The system of claim 14, wherein the hearing aid includes an in-the-canal (ITC) hearing aid.

18. The system of claim 14, wherein the hearing aid includes a receiver-in-canal (RIC) hearing aid.

19. The system of claim 14, wherein the hearing aid includes a completely-in-the-canal (CIC) hearing aid.

20. The system of claim 14, wherein the hearing aid includes a receiver-in-the-ear (RITE) hearing aid.
