Abstract

A multi-mode hearing aid includes a processor that is configured to selectively apply different hearing aid profiles to different input signals, such as a first sound signal received from a microphone and a second sound signal received from a transceiver, to produce first and second shaped output signals. The processor is configured to produce an output signal including at least one of the first shaped output signal and the second shaped output signal.

Claims

1. A muiti-mode hearing aid, the hearing aid comprising:

at least one microphone to convert sounds into a first signal;

a transceiver to receive a second signal through a communication channel; and

a processor adapted to apply a first hearing aid profile to the first signal to produce a first shaped output signal and a second hearing aid profile to the second signal to produce a second shaped output signal; and

a speaker coupled to the processor and adapted to produce an audible sound based on the first output signal if the multi-mode hearing aid is in a first mode, based on the second output signal if the multi-mode hearing aid is in a second mode and based on both the first output signal and the second output signal if the hearing aid is in a third mode.

2. The multi-mode hearing aid of claim 1, wherein the second signal comprises sound data received from a media player.

3. The multi-mode hearing aid of claim 2, wherein the media player is at least one of a television, radio, stereo speaker system, set-top box, and computer.

4. The multi-mode hearing aid of claim 1, further comprising:

an input port coupled to the processor and configurable to receive a connector of a wire to couple the processor to a media player to receive a third signal; and

wherein the processor adapted to apply a third hearing aid profile to the third signal to produce a third shaped output signal.

5. The multi-mode hearing aid of claim 1, wherein the processor is configured to filter audio content of the second signal from the audio content of the first signal to produce a filtered signal and apply a selected one of the first hearing aid profile and the second hearing aid profile to the filtered signal to produce a shaped output signal.

6. The multi-mode hearing aid of claim 1, wherein the processor is configured to:

synchronize and combine the first signal with the second signal to produce a combined signal and apply a selected one of the first hearing aid profile and the second hearing aid profile to the combined signal to produce a shaped output signal.

7. The multi-mode hearing aid of claim 1, wherein the processor is configured to:

synchronizes and combines the first output signal with the second output signal to produce a shaped output signal.
