FM System

What is a Frequency-Modulated (FM) System?

An FM System, an assistive listening device, is a wireless system that transmits sound via radio waves. The speaker wears a compact transmitter and microphone while the listener wears a portable receiver. The receiver transmits sound to your ears or, if you wear a hearing aid, directly to the hearing aid or cochlear implant if you have one. The receiver can also connect to a headset if you don’t wear a hearing aid.

 

How do FM hearing systems work?

A traditional FM System comprises of two main parts – a radio transmitter and radio receiver. The transmitter captures sound via a microphone or direct connection to a sound source and transmits to the receiver.

Transmitters and receivers vary dependent on the manufacturer. Some have manual controls only while others have manual controls with a small screen for menu selection to set the transmission frequency between the transmitter and receiver and select the use of the audio input. The screen may also show the battery level, frequency channel and direction of the microphone.

Why use FM hearing systems ?

A FM System empowers a hearing aid wearer with their own light weight, portable, flexible and discrete equipment that they can use in a great variety of daily situations where additional hearing assistance is required, as hearing aids alone, mainly due to background noise and distance, are not sufficient.

The legislation term “reasonable adjustments” has meant that there are businesses and organisations that have still not installed induction loops in strategic or customer facing areas and there are situations and places where there will probably never be induction loops. e.g. dining out, or sitting at a restaurant table.

While they should install induction loops a person with a FM System can almost go anywhere (they are not waterproof) with their equipment and therefore are less dependent on others.
