Abstract

Presented herein are stand-alone hearing aid adapters configured to enable the use of the recipient's hearing aid to detect and process ambient sound signals and to convert output signals generated by the acoustic hearing aid into input signals useable by the implantable hearing prosthesis for generation and delivery of stimulation to a recipient.

First claim

What is claimed is:

1. A stand-alone hearing aid adapter, comprising:
at least one input element configured to receive hearing aid output signals from an acoustic hearing aid;
an adaption module configured to convert the hearing aid output signals into implantable hearing prosthesis input signal, wherein the adaption module comprises an analog-to-digital converter and an audio encoder; and
a wireless transmitter configured to transmit the implantable hearing prosthesis input signals to an implantable hearing prosthesis.

2. The stand-alone hearing aid adapter of claim 1 , wherein the hearing aid output signals are electrical signals, and wherein the at least one input element is an electrical connector configured to mate with an acoustic receiver connector of the acoustic hearing aid.

3. The stand-alone hearing aid adapter of claim 1 , wherein the hearing aid output signals are acoustic signals transmitted by an acoustic receiver, and wherein the at least one input element is a microphone configured to sample the acoustic signals.

4. The stand-alone hearing aid adapter of claim 1 , further comprising a housing forming an earhook that is configured for attachment to an outer ear of a recipient, wherein the adaption module and the wireless transmitter are located in the housing.

5. The stand-alone hearing aid adapter of claim 1 , further comprising an in-the-ear housing configured to be inserted into an outer ear of a recipient, wherein the adaption module and the wireless transmitter are located in the in-the-ear housing.

6. The stand-alone hearing aid adapter of claim 1 , further comprising a battery.

7. A method, comprising:
receiving, at a hearing aid adapter in communication with an acoustic hearing aid, analog hearing aid output signals generated by the acoustic hearing aid based on detected sound signals;
converting, with an analog-to-digital converter in the hearing aid adapter, the analog hearing aid output signals into digital signals;
encoding, with an audio encoder in the hearing aid adapter, the digital signals into implantable hearing prosthesis input signals; and
wirelessly transmitting the implantable hearing prosthesis input signals from the hearing aid adapter to an implantable hearing prosthesis.

8. The method of claim 7 , further comprising:
wirelessly receiving the implantable hearing prosthesis input signals at the implantable hearing prosthesis; and
converting the implantable hearing prosthesis input signals into stimulation signals to evoke perception of the detected sound signals when delivered to a recipient of the implantable hearing prosthesis.

9. The method of claim 8 , wherein the converting the implantable hearing prosthesis input signals into stimulation signals is performed without sound processing operations.

10. The method of claim 7 , further comprising:
detecting the sound signals at an acoustic hearing aid; and
performing sound processing at the acoustic hearing aid to convert the detected sound signals into the hearing aid output signals.

11. The method of claim 7 , wherein receiving the hearing aid output signals comprises:
receiving electrical signals via an electrical connector configured to mate with an acoustic receiver connector of the acoustic hearing aid.

12. The method of claim 7 , wherein receiving the hearing aid output signals at the hearing aid adapter comprises:
receiving, via at least one input element, acoustic signals transmitted by an acoustic receiver, and wherein the at least one input element is a microphone configured to sample the acoustic signals.

13. An implantable hearing prosthesis system, comprising:
an implantable hearing prosthesis configured to be at least partially implanted in a recipient; and
a stand-alone hearing aid adapter configured to be coupled with an acoustic hearing aid and to wirelessly stream processed sound signals from the acoustic hearing aid to the implantable hearing prosthesis, wherein the stand-alone hearing aid adapter comprises an analog-to-digital converter and an audio encoder.

14. The implantable hearing prosthesis system of claim 13 , wherein the stand-alone hearing aid adapter is electrically coupled to the acoustic hearing aid, and wherein the processed sound signals are received by the stand-alone hearing aid adapter as electrical signals.

15. The implantable hearing prosthesis system of claim 13 , wherein the stand-alone hearing aid adapter is acoustically coupled to the acoustic hearing aid, and wherein the processed sound signals are received by the stand-alone hearing aid adapter as acoustic signals.

16. The implantable hearing prosthesis system of claim 13 , wherein the stand-alone hearing aid adapter comprises:
a housing forming an earhook that is configured for attachment to an outer ear of a recipient of the implantable hearing prosthesis, wherein a wireless transmitter is located in the housing for communication with a wireless receiver in the implantable hearing prosthesis.

17. The implantable hearing prosthesis system of claim 13 , wherein the stand-alone hearing aid adapter comprises:
an in-the-ear housing configured to be positioned in an outer ear of a recipient of the implantable hearing prosthesis, wherein a wireless transmitter is located in the in-the-ear housing for communication with a wireless receiver in the implantable hearing prosthesis, and wherein the analog-to-digital converter, audio encoder, and the wireless transmitter are located in the in-the-ear housing.

18. The implantable hearing prosthesis system of claim 13 , wherein the implantable hearing prosthesis is configured to:
wirelessly receive the processed sound signals from the stand-alone hearing aid adapter; and
convert the processed sound signals into stimulation signals for delivery to a recipient of the implantable hearing prosthesis.

19. The implantable hearing prosthesis system of claim 13 , wherein the implantable hearing prosthesis is a cochlear implant.

20. The implantable hearing prosthesis system of claim 19 , wherein the implantable hearing prosthesis is a totally implantable cochlear implant having an implantable wireless receiver.
