FM Hearing Systems – Adelaide


“What are FM Systems and how can they help children and adults with hearing loss?”

FM systems work by wirelessly transmitting sound directly from a microphone to a receiver (similar in appearance to hearing aids) worn by the listener. They boost the performance of hearing aids in a great variety of daily situations that are subject to background noise and distance.

Difficult listening environments

FM systems can be particularly useful in noisy environments, such as classrooms, restaurants, and public transportation. In these settings, background noise can make it difficult for people with hearing loss to understand speech and communicate effectively. FM systems can help overcome this problem by transmitting the speaker’s voice directly to the listener’s hearing aid or cochlear implant, reducing the impact of background noise.

FM Systems (auditory trainers) and children

For children with hearing loss, FM systems can be especially beneficial in school settings. Teachers can use FM systems to send their voice directly to a child’s hearing aid or cochlear implant, making it easier for the child to understand what’s going on in class and take part. Studies have shown that children who use FM systems in the classroom have better academic outcomes, higher self-esteem, and improved social skills compared to children who do not use FM systems.

Benefits for adults

For adults with hearing loss, FM systems can be useful in a variety of settings, including work, social gatherings, and other public places. FM systems can help people in these situations understand speech better, feel less tired, and communicate better, which improves their overall quality of life.

How does a FM System work?

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


The transmitter is responsible for capturing and transmitting the audio signal to the receiver worn by the listener. The transmitter usually looks like a small, portable device that can be carried around by the speaker or worn on their clothing. The microphone or input device can be a variety of types, such as a handheld microphone, a lapel microphone, or a headset microphone.



Direct Audio Input FM Receiver

If the hearing aid(s) or cochlear implant processor also has a Direct Audio Input a miniature receiver can be connected directly via an audio shoe (see the silver box on the bottom of the hearing aid shown here).

The miniature receiver is powered by the hearing aids’ batteries and the sound level received controlled by the hearing aid volume control. The “T” position is not used.
