Abstract

A personal listening device in a handheld form factor includes an input port for receiving an audio signal, a processor for selecting equalizer settings responsive to a selected hearing profile, an equalizer for equalizing the audio signal according to the equalizer settings, and an output port for outputting the equalized audio signal to a speaker, headphone, or other audio output device. The personal listening device also includes a tone generator and user input device coupled to the processor, configured to administer a sequence of tones, generate audio instructions, and receive user input, thereby administering a hearing test and generating a user hearing profile. The device may be operated to administer multiple tests and store multiple hearing profiles, and to provide hearing profiles to other devices.

Claims

1. A personal listening apparatus, comprising:

an audio input port;

an audio output port;

a user interface device operable to transform physical input to an electrical signal indicating user input;

a processor connected to receive an input audio signal from the audio input port, to provide an output audio signal to the audio output port, and to receive the user input from the user interface device; and

a memory operably associated with the processor;

the memory holding program instructions for;

administering a hearing test by providing a tone sequence to the audio output port and analyzing the user input from the user interface device;

determining a hearing profile from results of the hearing test indicative of hearing ability at different test frequencies; and

amplifying respective frequency bands of the input audio signal to compensate for deficiencies in hearing ability indicated by the hearing profile, to provide the output audio signal.

2. The apparatus of claim 1, wherein the audio input port comprises an IR receiver.

3. The apparatus of claim 1, wherein the audio input port comprises a wireless Bluetooth transceiver.

4. The apparatus of claim 1, wherein the audio input port comprises an FM receiver.

5. The apparatus of claim 1, wherein the audio input port comprises a USB port.

6. The apparatus of claim 1, wherein the audio input port comprises a stereo input jack.

7. The apparatus of claim 1, wherein the audio output port comprises a neck loop with an audio output jack.

8. The apparatus of claim 1, wherein the audio output port comprises a wireless Bluetooth transceiver.

9. The apparatus of claim 1, wherein the audio output port comprises an FM transmitter.

10. The apparatus of claim 1, wherein the audio output port comprises a USB port.

11. The apparatus of claim 1, wherein the user interface device comprises a touchscreen device adapted to output a graphical display.

12. The apparatus of claim 1, wherein the program instructions further comprise instructions for storing a plurality of different hearing profiles in the memory.

13. The apparatus of claim 1, wherein the program instructions further comprise instructions for selecting the hearing profile used in amplifying the input audio signal from a plurality of stored hearing profiles, in response to a selection signal received from the user interface device.

14. The apparatus of claim 1, wherein the program instructions further comprise instructions for enabling selection of a hearing profile in response to a selection signal received from the user interface device, and transmitting a selected hearing profile to an external device.

15. The apparatus of claim 1, wherein the program instructions further comprise instructions for preparing a graphical representation of the hearing profile for display by the user interface device.

16. A method for operating a personal listening device, comprising:

administering a hearing test by providing a tone sequence to an audio output port of a personal listening device, and analyzing input from a user interface device;

determining a hearing profile from results of the hearing test indicative of hearing ability at different test frequencies;

storing the hearing profile in a local memory;

receiving a first audio signal from an external source device;

amplifying respective frequency bands of the input audio signal to compensate for deficiencies in hearing ability indicated by the hearing profile, to provide an output audio signal; and

outputting the output audio signal to an external audio output device.

17. The method of claim 16, further comprising selecting the hearing profile used for amplifying the input audio signal from a plurality of stored hearing profiles, in response to a selection signal received from a user interface device.

18. The method of claim 16, further comprising determining different hearing profiles, and storing the different hearing profiles in the memory.

19. The method of claim 18, further comprising transmitting a selected one of the different hearing profiles to an external device.

20. The method of claim 16, further comprising preparing a graphical representation of the hearing profile for display by a display device.
