Abstract

Disclosed herein, among other things, are apparatus and methods to detect signals connected to a direct audio input port of a hearing assistance device. According to one embodiment, a hearing assistance device includes a processor and a direct audio input (DAI) port including a signal line connected to the processor. The DAI port is configured to connect to an external device, and the processor is programmed to detect audio signals of interest on the signal line and to process the audio signals of interest when detected as programmed. Other embodiments are possible without departing from the scope of the present subject matter.

Claims

1. A hearing assistance device, comprising:

a processor; and

a direct audio input (DAI) port including a signal line connected to the processor,

wherein the DAI port is configured to connect to an external device, and the processor is programmed to detect audio signals of interest on the signal line and to process the audio signals of interest when detected as programmed.

2. The device of claim 1, further comprising a microphone, and wherein the processor is programmed to mix the audio signals of interest with sounds detected by the microphone.

3. The device of claim 2, wherein the sounds detected by the microphone are attenuated by a programmable amount and the audio signals of interest are played to the wearer.

4. The device of claim 3, wherein the programmable amount is approximately 6 dB.

5. The device of claim 1, further comprising the external device, wherein the external device includes an FM device.

6. The device of claim 5, wherein, when the FM device is off or out of range, the DAI port is in an off state so as to not receive noise coming from the FM device.

7. The device of claim 5, wherein, when the FM device is on and provides an audio signal, the DAI port is in an active state to receive the audio signals.

8. The device of claim 5, wherein, when the FM device is on but no audio is present for a predetermined time, the DAI port is configured to enter a dormant state.

9. The device of claim 1, further comprising the external device, wherein the external device includes a wireless receiver.

10. The device of claim 9, wherein the wireless receiver includes a BLUETOOTH receiver.

11. The device of claim 1, further comprising the external device, wherein the external device includes a magnetic induction receiver.

12. The device of claim 1, further comprising the external device, wherein the external device includes a wired audio connection.

13. The device of claim 1, further comprising the external device, wherein the external device includes a cellular telephone.

14. A method, comprising:

detecting a signal of interest from a signal received at a direct audio input (DAI) port of a hearing assistance device; and

processing the signal of interest based on programming of a processor connected to the DAI port.

15. The method of claim 14, wherein detecting the signal of interest includes comparing a level of the signal of interest to multiple thresholds.

16. The method of claim 15, wherein processing the signal of interest includes selecting from a plurality of processing modes to enter upon detecting the signal of interest.

17. The method of claim 16, wherein one of the plurality of processing modes includes processing only the signal of interest.

18. The method of claim 16, wherein one of the plurality of processing modes includes mixing a signal from a microphone of the hearing assistance device with the signal of interest detected at the DAI port.

19. The method of claim 18, wherein mixing the signal from the microphone with the signal of interest detected at the DAI port includes providing a preference to the DAI signal as compared to the microphone signal.

20. The method of claim 19, wherein providing a preference to the DAI signal includes decreasing an input level of the microphone signal by at least 6 dB.
