9. A system for adjusting audio output as in claim 6 wherein the electrical sound signal modifier is adapted to filter target freguencies, based upon information in the signal transmitted by the signal transmitter, which need amplitude and/or frequency modification.

10. A system for adjusting audio output as in claim 6 wherein the electrical sound signal modifier comprises a bandpass filter array.

11. A system for adjusting audio output as in claim 10 wherein the electrical sound signal modifier comprises a frequency shifter.

12. A system for adjusting audio output as in claim 1 wherein the at least one acoustic transducer comprises speakers.

13. A system for adjusting audio output as in claim 1 wherein the transmitter unit comprises:

a battery;

the signal transmitter connected to the battery for transmitting a wireless signal; and

the memory connected to the signal transmitter, the memory comprising hearing information regarding a user'"'"'s auditory characteristics,

wherein the signal transmitter is adapted to transmit at least a portion of the hearing information stored in the memory.

14. A system for adjusting audio output as in claim 13 wherein the memory comprises a nonvolatile memory.

15. A system for adjusting audio output as in claim 13 wherein the transmitter unit is adapted to broadcast the hearing information at periodic time intervals.

16. A system for adjusting audio output as in claim 13 wherein the transmitter unit is adapted for reprogramming of the memory.

17. A system for adjusting audio output as in claim 1 wherein the sound generating system comprises:

a processor;

the sound generator being provided as a first sound generator coupled to the processor;

a second sound generator coupled to the first sound generator by a programmable sound signal modifier;

a combiner for combining an output from the second sound generator with a portion of an output from the signal modifier; and

wherein the signal receiver comprises a wireless signal receiver coupled to the processor, the receiver being adapted to receive a hearing information signal containing a user'"'"'s auditory characteristics,

wherein the processor is adapted to configure the modifier based upon the hearing information signal received by the receiver.

18. A system for adjusting audio output as in claim 17 wherein the signal modifier is adapted to filter target frequencies, based upon information in the hearing information signal, which need amplitude and/or frequency modification.

19. A system for adjusting audio output as in claim 17 wherein the sound signal modifier comprises a bandpass filter array.
