What is FM Systems?

FM systems, often referring to Frequency Modulation systems, are commonly used in assistive listening devices. They transmit audio signals wirelessly from a source (like a teacher's microphone) to a receiver worn by the listener (like a student with hearing loss). This improves the signal-to-noise ratio, making it easier to hear the desired sound by reducing background noise and distance-related signal degradation. FM systems are also used in radio broadcasting and two-way communication.
