FM Systems

A personal frequency modulation (FM) system uses radio waves to send speech and other signals to hearing aids and cochlear implants. FM is the same type of signal as your FM radio, only it’s tuned to a frequency band designated for personal use. A parent of a deaf child might encounter the term FM Systems when researching assistive technology options for their child. They may learn about FM Systems as a way to enhance their child’s ability to hear and communicate in various environments.
