There are many types of Assistive Listening Devices, ranging from sophisticated technology in a theatre or auditorium, to personal home systems. Some types of ALD’s are:
Personal Listening Systems: Designed to carry the sound from source to listener with minimized background noise. They include personal amplifiers, FM systems, and auditory trainers.
TV Listening Systems: Designed for listening to TV, radio, or stereos with minimal interference from background noise. They ensure a comfortable volume level for everyone in the room.
Direct Audio Input Hearing Instruments: These are actual hearing instruments with audio input connections (usually wires), which can be connected directly to the source (TV, radio, stereo, microphones, auditory trainers, and personal FM systems).
Telephone Amplifying Device: Enables you to listen on the phone at a comfortable level without feedback or background noise. You must have a hearing instrument that has a T-Coil feature and is telephone compatible. These two components communicate with one another so telephone conversations are easy to hear and understand. Ask your hearing specialist if you have the proper hearing instrument for this device.
Cell Phones: Most hearing instruments can be used with cell phones, however, digital models can create constant noise, distortion, or feedback with a cell phone. Ask your hearing specialist for advice about how to best use your cell phone with your hearing instruments. |
