A frequency-modulated (FM) system is a listening system in which the speaker wears a microphone and the listener wears a radio receiver that is attached to the hearing aid(s).

An FM system will minimize the effects of background noise by decreasing the signal to noise ratio and permitting a clearer reception of the speaker’s voice.

An FM system is ideal for children in a classroom setting and active adults who attend meetings, work in the courtroom, etc.
