What are Assistive Listening Devices (ALDs)?
You may have certain communication needs that
cannot be solved by just using hearing aids. These
situations may involve telephone, radio, television,
or the inability to hear the door chime, telephone
bell, and alarm clock. Special devices have been
developed to solve these problems.

| Like hearing aids, assistive listening devices and alerting
devices make sounds louder. Typically, a hearing aid makes
all sounds in the environment louder. Assistive listening
devices and alerting devices can increase the loudness
of a desired sound, like a radio or television, a public
speaker, or an alarm system, or may make an auditory alarm
(such as a smoke signal) into a visual alarm (such as
a strobe light). |
