What are FM Systems?
An FM system is one that uses Frequency Modulation to transmit sound. It is a wireless transmission of a radio signal from a transmitter to a receiver.

Why Use an FM System?
Less expensive than a Hearing Loop (initially) – Hearing Loops take more labor and equipment to install a proper system initially.
Easy to install – An FM system is easily installed by connecting a transmitter to an audio output.
Considerations of an FM System?
Signal loss – FM’s suffer from loss of signal and privacy issues as the signal can travel significant distances and through walls.
Personal receiver required – There is no option to directly send a FM signal from a transmitter directly to a hearing aid or cochlear implant. A different frequency is used at each venue requiring the syncing of a receiver to a venues transmitter. Due to the use of a personal receiver, it is obvious that a person is having trouble and many people are uncomfortable putting their hearing disability out there for everyone to know. Most people would prefer to not use the system at all.
