An FM system is a wireless system that transmits sound directly from source
to ear. It consists of an FM microphone and one or two FM receivers.
What is an FM system?
|  | The FM microphone is actually a microphone connected to, or inside, a radio transmitter. The microphone picks up the desired signal, which is often the voice of a person that you
want to listen to. The transmitter then sends it via radio waves directly to the FM receiver. The FM receiver, in turn, is connected to the hearing instrument. The
sound is delivered to the hearing instrument, the hearing instrument applies the right amplification
and the voice can be heard as if the talker was speaking from a very short distance. |
There
are also
Phonak FM receivers for cochlear implants and bone-anchored hearing aids. However, the basic principle
remains the same.
