Abstract
The light output of an IR LED mounted on a cellular telephone is modulated by the audio output of the telephone and made incident upon a photodiode mounted to an ITE-type or canal-type hearing aid. The electrical signal output from the photodiode is routed through a bandpass filter, demodulated in a demodulator and amplified and/or processed in the hearing aid circuit.
