An FM system consists of a receiver and a separate microphone. The listener (hard of hearing person) wears the receiver, and the microphone is directed at or worn by the speaker. FM systems help overcome the challenge of background noise, echoing environments, and distance from the speaker, problems that can arise in both small and large group settings. FM systems are helpful in meetings, classes and conferences. By focusing the microphone on the speaker the hard of hearing person is better able to hear a specific voice, as background noise is eliminated or greatly reduced.
