Abstract

Sound quality is enhanced in a sound system including handsets and headsets. Handset sound enhancing algorithms are implemented in a handset. The handset automatically determines which, if any, of a plurality of headset sound enhancing algorithms are active in a headset in communication with the handset. The handset determines how to use the handset sound enhancing algorithms in a sound processing channel based on which of the headset sound enhancing algorithms are active in the headset.

Claims

1. A method for enhancing sound quality in a communication system, the communication system including a plurality of interconnected handsets, the method comprising:

determining a first set of sound enhancing algorithms in a first handset, the first set of sound enhancing algorithms optimizing transmission through an interconnection channel;

transmitting an indication of the set of sound enhancing algorithms through the interconnection channel to a second handset; and

automatically determining in the second handset which second set of sound enhancing algorithms to use in the second handset based on the indication transmitted from the first handset.

2. The method of claim 1 wherein determining a first set of sound enhancing algorithms is based on which of a plurality of headsets is in communication with the first handset.

3. The method of claim 1 wherein transmitting the indication of the set of sound enhancing algorithms further comprises wirelessly transmitting the indication of the set of sound enhancing algorithms through the interconnection channel to the second handset.

4. The method of claim 1 wherein the first handset includes a microphone and a speaker.

5. The method of claim 1 wherein the second handset includes a microphone and a speaker.

6. A method for enhancing sound quality in a communication system, the communication system including a handset in communication with a headset, the method comprising:

implementing a set of sound enhancing algorithms in the handset, each sound enhancing algorithm in the set of sound enhancing algorithms operative to be used in a sound processing channel;

receiving in the handset a signal from the headset indicating an operating condition of the headset; and

automatically determining in the handset which sound enhancing algorithms in the set of sound enhancing algorithms to use in the sound processing channel based on the signal received from the headset.

7. The method of claim 6 wherein receiving in the handset the signal from the headset indicating the operating condition of the headset further comprises wirelessly receiving in the handset the signal from the headset indicating the operating condition of the headset.

8. The method of claim 6 wherein the handset includes a microphone and a speaker.

9. The method of claim 6 wherein the headset includes a microphone and a speaker.

10. An apparatus for enhancing sound quality in a communication system, the apparatus comprising:

a handset including a set of sound enhancing algorithms, each sound enhancing algorithm in the set of sound enhancing algorithms being operative to be used in a sound processing channel, the handset being configured to;

receive a signal from a headset indicating an operating condition of the headset; and

automatically determine at least one first sound enhancing algorithm from the set of sound enhancing algorithms to use in the sound processing channel based on the signal from the headset.

11. The apparatus of claim 10 wherein the handset is further configured to wirelessly receive the signal from the headset indicating the operating condition of the headset.

12. The apparatus of claim 10 wherein the handset includes a microphone and a speaker.

13. The apparatus of claim 10 wherein the headset includes a microphone and a speaker.
