Intergrated hearing aid for telecommunications devices |
摘要 |
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.
