Hard of hearing people can dream of a future when hearing
aids might also serve as wireless loudspeakers, delivering
clear, sharp, customized, sound right from inside their
ears. They can dream of communities where churches, auditoriums,
drive-up business windows and home TV rooms all broadcast
their sound directly through these in-the-ear loudspeakers.
Thanks to the refinement of "induction loop"
systems that transmit directly to hearing aids with telecoils
(T-coils), that future can be now! What wi-fi is to laptops,
loop systems are to hearing aids. |

Why are assistive listening systems needed?
It's wonderful that churches, schools, and business have made
themselves accessible to the visible minority of people in
wheelchairs...more
Why are hearing loops the preferred assistive
learning system?
Unlike FM and infrared listening systems, loop systems that

What hearing aids have telecoils and can
receive loop broadcasts?
Most behind-the-ear hearing aids routinely come with telecoil
sensors, as do many in-the-ear hearing aids. These are the
hearing aids typically... more

“Venues and service points where sound
is broadcast shall offer assistive listening, such as induction
loop systems designed to the IEC 60118-4:2006 standard, that
broadcast sound directly to hearing aids and cochlear implants,
enabling them to serve as customized, wireless loudspeakers
(without the need for extra equipment).”
~ Hearing Loops International Conference, 2009 (PDF)
Britain's Royal National Institute for Deaf
People (RNID)
notes that "Induction loops are vital to ensure accessibility
for hearing aid wearers," and offers suggestions for
installing and checking them.
"On behalf of Michigan's hard
of hearing persons, HLA-MI [the Hearing Loss Association
of Michigan] recommends that Michigan's public places, as
defined by ADA and MPDCR, and where sound is broadcast,
install assistive listening systems that broadcast directly
through hearing aids and cochlear implants. . ." more
"In all new and extensively remodeled
buildings, wherever there is a public address system, a
loop should be permanently installed. . . . When
there is a loop, all a hard of hearing person has to do
to be able to hear, is click on the T-switches on their
hearing aids."
~Hearing
Loss Association of California

Recent nontechnical articles explaining loop systems have been
authored by
- Scientific
American (2010)
explains the push to make assistive listening hearing aid-compatible.
- Award-winning audiological researcher-writer Mark
Ross.
- Hearingloop.org creator, David Myers in blog
entries for the Better Hearing Institute, and in Hearing
Loss (2008, PDF), the Hearing
Journal (2008, PDF), Advance
for Audiologists (2008), Hearing
Health (2007, PDF), and
other articles.
- Denise
Portis, offering an eloquent first-person
story (PDF).
- California audiologist Bill
Diles describes how his installation of 1500 home
TV room loops has impacted his patients and his practice.
The momentum toward hearing aid compatible
assistive listening is growing, thanks to recent developments:
- Loop systems have been mandated for inclusion in all London
Transport ticket offices and all London
taxis, and are being tested in New
York City taxis.
- Telecoils also enhance phone listening with all landline
phones and more and more cell phones. The FCC
is requiring digital phone manufacturers to make telecoil-compatible
phones available at every price level. For more cell phone
information, see here.
- More and more hearing aids (62 percent in two recent surveys)
come with telecoils, as do nearly all the behind the ear
aids worn by those most needing hearing assistance.
- More and more American venues are being looped. These
include the U.S. House of Representatives' main chamber.
Hearing loss organizations are promoting the technology
in West Michigan, Arizona, New Mexico, Wisconsin, and elsewhere.
- Gerald R. Ford International Airport (Grand Rapids, MI),
serving 2 million passengers annually, becomes only U.S.
airport to offer assistive listening. (See press
release; see more
airport photos; see Grand Rapids Press article.)
