Assistive listening and technology devices
Assistive listening devices are devices designed to improve hearing in specific listening situations. Some are designed for use with hearing aids or cochlear implants. Others are designed to be used alone.
Many devices used in conjunction with hearing aids require a telecoil (T-switch). Telecoils are a mechanism inside the hearing aid that enable the hearing aid to be used directly with most assistive listening devices and certain telephones.
Other devices include infrared systems, FM systems, wired devices like the Pocket Talker and more.
