What is an assisted listening device?
An assisted listening device, or assisted listening system, is a tool to bring sounds more directly into the ear to make them easier to hear. They also reduce background noise and make the sounds people want to hear, such as voices, louder. An ALD has three parts:
- A microphone
- A transmitter to send the sound to the ear
- A receiver to bring the sound into the ear
Who can use an assisted listening device?
An assisted listening device can be used for anyone who has trouble hearing, whether they have full or mild hearing loss.
There are many ADL types including:
- FM Systems- These use radio broadcast to transmit sounds
- Infrared Systems- These use light waves to transmit sound.
- Inductive Loop Systems- These use magnetic field to transmit sound.
