In-car assistive audio technologies for users with hearing loss
A hearing application for a vehicle audio system may include at least one speaker configured to play playback content, and at least one hearing application programmed to receive optimization parameters from a hearing device within the vehicle, the optimization parameters including signal processing parameters specific to the hearing device, apply the optimization parameters to the playback content, and transmit the playback content for playback by one of the hearing device and/or at least one speaker.
1. A hearing application for a vehicle audio system, the system comprising:
at least one speaker configured to play playback content;
at least one hearing application programmed to
receive optimization parameters from a hearing device within the vehicle, the optimization parameters including signal processing parameters specific to the hearing device;
apply the optimization parameters to the playback content; and
transmit the playback content for playback by one of the hearing device and the at least one speaker.
2. The system of claim 1 , wherein the hearing application is further programmed to determine that the hearing device is in an in-ear state or an out-of-ear state.
3. The system of claim 2 , wherein the hearing application is further programmed to transmit the playback content to the hearing device in response to the hearing device being in an in-ear state.
4. The system of claim 3 , wherein the hearing application is further programmed to transmit the playback content to the at least one speaker concurrent with transmitting the playback content to the hearing device.
5. The system of claim 4 , wherein the hearing application is further programmed to apply latency to the playback content transmitted to the hearing device to avoid reverberance, wherein the playback content at the at least one speaker is not optimized.
6. The system of claim 2 , wherein the hearing application is further programmed to transmit the playback content to the at least one speaker in response to the hearing device being in an out-of-ear state.
7. The system of claim 1 , wherein the optimization parameters are specific to the hearing device.
8. The system of claim 1 , wherein the hearing device and the hearing application communicate via a wireless communication protocol.
9. A hearing application for a vehicle audio system, the system comprising:
at least one speaker configured to play playback content;
at least one hearing application programmed to
identify at least one user within the vehicle;
receive an audio-consumer profile associate with the user, the audio-consumer profile including signal processing parameters specific to the user;
apply the optimization data to the playback content; and
transmit the playback content for playback by the at least one speaker.
10. The system of claim 9 , wherein the audio-consumer profile includes optimization parameters from a hearing device associated with the at least one user, the optimization parameters including signal processing parameters specific to the hearing device.
11. The system of claim 10 , wherein the optimization parameters are received from a vendor of the hearing device.
12. The system of claim 11 , wherein the hearing application is further programmed to transmit the playback content to the at least one speaker in response to the hearing device being in an out-of-ear state.
13. The system of claim 11 , wherein the hearing device and the hearing application communicate via a wireless communication protocol.
14. The system of claim 13 , wherein the hearing application is further programmed to transmit the updated audio-consumer profile to a remote server.
15. The system of claim 10 , wherein the hearing application is further programmed to determine that the hearing device is in an in-ear state or an out-of-ear state.
16. The system of claim 15 , wherein the hearing application is further programmed to transmit the playback content to the hearing device in response to the hearing device being in an in-ear state.
17. The system of claim 16 , wherein the hearing application is further programmed to transmit the playback content to the at least one speaker concurrent with transmitting the playback content to the hearing device.
18. The system of claim 17 , wherein the hearing application is further programmed to apply latency to the playback content transmitted to the hearing device to avoid reverberance, wherein the playback content at the at least one speaker is not optimized.
19. The system of claim 9 , wherein the hearing application is further programmed to receive user preferences from user input and update the audio-consumer profile based on the user preferences.
20. The system of claim 9 , wherein the hearing application is further programmed to receive aggregated system data from a remote server and apply machine learning to the audio-consumer profile to update the audio-consumer profile.
