Assistive Listening Systems
For people who have difficulty hearing in large groups, at a distance, or in noisy environments, Assistive Listening Systems are helpful.
- A telephone amplifier enables some deaf and hard-of-hearing people to use the telephone by raising its volume.
- An induction loop is a wire circling a given area connected to an amplifier and the speaker's microphone.
- An FM system has a microphone/transmitter and a receiver that allows the listener to use a headset, earphone, or hearing aid with a direct audio input boot.
- An infrared system utilizes an emitter and a special receiver headset that picks up "infrared" light containing sound signals that are then directed into the ear.
- A one-to-one communicator consists of a microphone, small amplifier, and headphone.
- A sound field amplification system includes a wireless microphone which transmits speech to speakers strategically placed within a conference room.
