Types of Assistive Listening Devices


If you are not always able to hear speech as clearly as you would like, an assistive listening device may be able to help. There are many types of assistive listening devices that can enhance your ability to hear live speakers, phone conversations, and television dialogue.


1063863-ampAn amplifier is a device that increases sound levels while reducing background noise. Ideal for carrying with you when you are out and about. Most personal amplifiers are comparable in size to cell phones. Some utilize directional microphones, allowing you to angle them toward the sound source. The amplified sound can then be received through a connected earpiece or headset.

FM Systems

FM systems can be found in classrooms and other learning spaces. In an FM setup, a speaker addressing a large group wears a microphone, and the captured audio is transmitted over FM radio to listeners wearing receivers tuned to the designated frequency. Personal FM systems for direct conversations are also available.

Looping Systems

An induction loop system uses a thin wire looped around a room to create an electromagnetic field. When audio is transmitted through a microphone or other sound source in the room, the telecoil installed in most hearing aids and cochlear implants will automatically receive amplified sound via this field. For listeners without telecoils, wearable loop receivers are also an option.
An assistive listening device may be the hearing solution for you. For more information on different types of assistive listening devices, call Evolution Hearing in Charlottesville at 434-260-8007.
