Due to noisy settings and distance, there are certain situations in which hearing aids alone are insufficient to help a person hear better, as is the case in classrooms, meetings and nursing homes. This is where the FM system comes in handy. It is a wireless system that connects a person’s hearing aid to a sound source in order to help them better understand speech.
The FM system is a conveniently pocket-sized device consisting of two parts: A transmitter (a microphone used by the speaker) and a receiver (which is attached to the hearing aid). By tuning both the transmitter and the receiver to a specific radio frequency, transmissions remain unaffected by other wireless signals in the area, subsequently offering clear, high-quality sound transmissions. Next, the transmitter picks up the speaker’s speech and sends it to the receiver in the form of harmless radio waves, which the receiver streams into the hearing aid directly.
