Abstract

A user'"'"'s individual hearing characteristics are obtained and stored. Those characteristics are sent to the far end cellular telephone. The vocoder in the far end cellular telephone voice-codes the information based on the characteristics.

Claims

1. A hearing compensated portable telephone, comprising:

a memory, storing information indicative of a user'"'"'s hearing profile;

a telephone functional part, enabling coded communication with a far-end telephone; and

a controller part, which requests said far-end telephone to adjust an aspect of its coding, based on said information in said memory.

2. A telephone as in claim 1, wherein said telephone functional part includes a digital voice coder.

3. A telephone as in claim 1, further comprising a user interface, enabling changing said information.

4. A telephone as in claim 3 wherein said user interface operates by allowing selection of a profile from a plurality of prestored profiles.

11. A telephone as in claim 1, wherein said command requests the telephone to emphasize certain frequencies.

5. A method of communication comprising:

obtaining information indicative of a user'"'"'s hearing profile in a first communicating element;

communicating information indicative of said hearing profile to a second communicating element; and

using said information to change voice coding characteristics in said second communication device.

6. A method as in claim 5 wherein said using comprises digitally coding voice by emphasizing certain frequency bands based on said hearing profile.

7. A method as in claim 5 wherein said using comprises adjusting amounts of power for each frequency band based on the user'"'"'s hearing characteristics in said band.

8. A method as in claim 5 wherein said communicating is via IS-95.

9. A method as in claim 5 wherein said obtaining comprising selecting a prestored hearing profile.

10. A method as in claim 5 wherein said obtaining comprises dynamically adjusting a hearing characteristic.
