A FM system is a type of wireless hearing system that allows transmission of sound from speaker to listener via an FM signal (radio signal).
The person who is speaking wears or holds a microphone. The listener wears a FM receiver on their ears. The transmission from speaker to listener through a wireless FM signal allows for a cleaner sound quality. It helps for listening in background noise or when at a distance, such as when in an auditorium, place of worship, or classroom.
A FM system is a type of assistive listening device that may be used with hearing aids or as an alternative to hearing aids. It may be recommended for adults with poor speech discrimination or children with Auditory Processing Disorder.
