ABSTRACT:
Systems, devices and methods are provided for selectively coupling hearing aids to electromagnetic fields. One aspect relates to a hearing aid device. In various embodiments, the hearing aid device includes an induction signal receiver for receiving induction signals, a microphone system for receiving acoustic signals, a hearing aid receiver, and a signal processing circuit. The signal processing circuit includes a proximity sensor for detecting an induction source. The signal processing circuit presents a first signal to the hearing aid receiver that is representative of the acoustic signals. When the induction source is detected, the signal processing circuit presents a second signal to the hearing aid receiver that is representative of the induction signals and transmits a third signal representative of the induction signals from the hearing aid device to a second hearing aid device. Other aspects are provided herein.
