Abstract
A system integrates a hearing aid with devices such as wireless telephones, advantageously avoiding radio frequency (RF) interference. In one embodiment, a processor transforms an electrical signal to compensate for a hearing impairment. The function used for signal transformation can be accessed via a processor memory enhancement such as a smart card. A digital-to-analog converter (DAC) converts the transformed signal to an analog signal, which then goes to an amplifier and speaker. In other embodiments, an analog amplifier transforms the electrical signal.
Claims22
A system for compensating for hearing impairment comprising:
- an electronic device for producing sound in response to an electrical signal;
- and
- a hearing aid device for compensating for a hearing impairment including a hearing aid amplifier, said hearing aid device intercepting the electrical signal, transforming the electrical signal according to the hearing impairment, and generating sound according to the transformed electrical signal.
A wireless communications system comprising:
- a wireless telephone including:
- a receiver;
- a transmitter;
- a microphone;
- a telephone speaker;
- and
- a hearing aid device including a hearing aid amplifier.
A method of compensating for hearing impairment comprising:
- inputting an electrical signal into an electronic device that produces sound in response to an input electrical signal;
- intercepting, by a hearing aid device, said electrical signal;
- transforming, by said hearing aid device, said electrical signal according to a hearing impairment;
- and
- outputting, from said hearing aid device, sound according to the transformed electrical signal.
