Vehicle assistive hearing

1. A method for vehicle assistive hearing comprising:

transmitting an assistive listening device pairing signal into a vehicle;

identifying a plurality of digital audio sources in the vehicle, wherein at least one of the digital audio sources is a vehicle alert system for the vehicle;

categorizing a priority of the plurality of digital audio sources;

generating a stream of audio from the plurality of digital audio sources with volume adjusted for each digital audio source according to the priority of the digital audio source, wherein two of the plurality of digital audio sources are merged in the stream of audio, wherein a relatively higher volume is given to a digital audio source with a higher priority of the two of the plurality of digital audio sources; and

transmitting the stream of audio for a paired assistive listening device.

2. The method of claim 1 , wherein the plurality of digital audio sources comprises at least one of a navigation prompt system, advanced driver assistance systems (ADAS) chimes, hands free telephony (HFT), in-car communication (ICC) systems, music streaming services, and ambient audio obtained from a microphone on an outside of the vehicle.

3. The method of claim 1 , wherein an audio source with a priority level lower than audio from three other audio sources is muted for a duration that the three other audio sources are providing audio to a stream generator.

4. The method of claim 1 , wherein a transmitter of the paired assistive listening device pairing signal uses a wireless communication technology.

5. The method of claim 1 , wherein the plurality of digital audio sources comprises audio from a microphone attached to an external surface of the vehicle.

6. The method of claim 5 , comprising assigning a high priority to audio captured by the microphone in response to a determination that the audio includes a siren from an emergency vehicle.

7. The method of claim 5 , wherein the microphone captures a stereophonic audio where directionality of the stereophonic audio is preserved in generating the stream of audio and transmitting the stream of audio for the paired assistive listening device.

8. The method of claim 1 , comprising transmitting the stream of audio for playback on an audio speaker system installed in the vehicle.

9. The method of claim 1 , comprising transmitting the stream of audio for a second paired assistive listening device.

10. A non-transitory, computer readable storage device for vehicle assistive hearing comprising instructions that when executed on a processor, cause the processor to:

transmit an assistive listening device pairing signal into a vehicle;

identify a plurality of digital audio sources in the vehicle, wherein at least one of the digital audio sources is a vehicle alert system for the vehicle;

categorize a priority of the plurality of digital audio sources;

generate a stream of audio from the plurality of digital audio sources with volume adjusted for each digital audio source according to the priority of the digital audio source, wherein two of the plurality of digital audio sources are merged in the stream of audio, wherein a relatively higher volume is given to a digital audio source with a higher priority of the two of the plurality of digital audio sources; and

transmit the stream of audio for a paired assistive listening device.

11. The storage device of claim 10 , wherein the plurality of digital audio sources comprises at least one of a navigation prompt system, advanced driver assistance systems (ADAS) chimes, hands free telephony (HFT), in-car communication (ICC) systems, music streaming services, and ambient audio obtained from a microphone on an outside of the vehicle.

12. The storage device of claim 10 , wherein an audio source with a priority level lower than audio from three other audio sources is muted for a duration that the three other audio sources are providing audio to a stream generator.

13. The storage device of claim 10 , wherein a transmitter of the assistive listening device pairing signal uses a wireless communication technology.

14. The storage device of claim 10 , wherein the plurality of digital audio sources comprises audio from a microphone attached to an external surface of the vehicle.

15. The storage device of claim 14 , wherein the microphone captures a stereophonic audio where directionality of the stereophonic audio is preserved in generating the stream of audio and transmitting the stream of audio for the paired assistive listening device.

16. A system for vehicle assistive hearing comprising:

a plurality of digital audio sources in a vehicle to generate audio wherein at least one of the digital audio sources is a vehicle alert system for the vehicle; and

an audio streamer in an infotainment control unit of the vehicle to create a stream of audio from the plurality of digital audio sources with volume adjusted for each digital audio source according to a priority of the digital audio source, wherein the audio streamer is to transmit the stream of audio for an assistive listening device, wherein two of the plurality of digital audio sources are merged in the stream of audio, wherein with a relatively higher volume is given to a digital audio source with a higher priority of the two of the plurality of digital audio sources.

17. The system of claim 16 , comprising a microphone attached to an outside of the vehicle to capture ambient audio and act as one of the plurality of digital audio sources.

18. The system of claim 16 , comprising a stream transmitter to transmit the generated stream to an audio speaker system installed in the vehicle.

19. The method of claim 1 , comprising switching a priority level in the plurality of digital audio sources in response to detecting that the vehicle is parked.

20. The method of claim 1 , comprising switching a priority level in the plurality of digital audio sources in response to detecting that the vehicle is moving.
