A Hearing Aid That Cuts Out All the Clatter

The
Hearing Loss Association of America, the largest group representing
people with hearing problems, has joined with the American Academy of
Audiology in a campaign to make loops more common in the United States.
This technology is a cost-efficient way to provide benefits that even the
most expensive hearing aids cannot deliver. A hearing loop, typically
installed on the floor around the periphery
of a room, is a thin strand of copper wire radiating electromagnetic
signals that can be picked up by a tiny receiver already built into most
hearing aids and cochlear implants. When the receiver is turned on, the
hearing aid receives only the sounds coming directly from a microphone,
not the background cacophony. Included in this article is a story about
composer Richard Einhorn and his first encounter with the hearing loop
system.
