Induction Loops
An induction loop is basically a coil of wire that
surrounds an area in which people with hearing loss will be located.
Loops are typically installed under the carpet or around the tops of the
walls of a room, where they meet the ceiling. The loops are attached to
an amplifier, which is fed by a sound source - a microphone, radio, or
whatever the users want to hear.
Users switch their hearing aids to activate the telecoil
(T-coil), and the signal in the induction loop activates the telecoil to
transmit the sound to the hearing aid. This is the same method that is
used to enable people with hearing loss to use their telecoils to hear
on the phone; the difference is that the loop used to drive the hearing
aid telecoil is a lot bigger than the one in a phone.
A loop is a great assistive device for people who have
enough residual hearing to be able to use it. Many lecture halls,
theaters and meeting rooms have loops installed. And they're becoming
increasingly common in people's homes.

The modern classical composer Richard Einhorn lost
most of his hearing in 2010, suddenly and irreversibly, when he was 57. He
feared he would never enjoy a live musical performance again. A year
later, however, he attended a production of the musical "Wicked" at the
Kennedy Center in Washington, DC, which had temporary hearing loops
installed for those attending the annual Hearing Loss of America
Convention. Mr. Einhorn wrote to the Kennedy Center after the performance
to urge them to install permanent hearing loop technology. "That evening
was, by far, the clearest, most enjoyable performance I've attended since
my hearing loss," he said. "It meant so much to me to sit in a concert
hall and, for the first time in a year, actually enjoy a live performance
again." More and more people with hearing loss across America are having
the revelation Mr. Einhorn experienced. Thousands of new locations, from
churches to theaters to the New York City subway system, have been looped
in the two years since the American Academy of Audiology and the Hearing
Loss Association of America collaborated to create the public education
campaign, "Get in the Hearing Loop."

New technology has dramatically improved the
quality of hearing aids in the past decade, but some say an old technology
could have the most profound impact in the decade to come on millions of
people with hearing loss. Just as WiFi connects people to the Web in wired
places, hearing loops - simple wires that circle a room or part of a room
- can connect many hearing aids and cochlear implants directly to sound
systems. Bypassing ambient noise, this wireless connection lets users
clearly hear actors on stage, the person in the subway information booth,
their ministers or rabbis, announcements at an airport, even their own
television sets. But as with all things that seem too good to be true,
there's a catch. Actually two catches. First, for hearing loops to work,
users' hearing devices have to be equipped with something called a
telecoil - which is common but not universal. Second, public places have
to be "looped." In the United States, very few are.

An Audio Frequency Induction Loop System, or AFILS,
is a relatively new acronym for an old approach to assistive listening
that is more commonly known as a "hearing loop". Using the full term may
seem redundant to professionals in the hearing health industry because we
know that the product of the inductive transmission is an audio signal,
typically one that conveys speech information. Using the term AFILS or
hearing loop is a matter of personal preference. But, it is imperative
that AFILS/hearing loops are distinguished from neck loops. A neck loop is
often supplied as a coupler to frequency-modulation (FM) systems and/or
infra-red (IR) systems. At the outset, I will mention that all three of
these assistive listening devices (ALDs) are capable of providing hearing
instrument compatible auditory access through a telecoil! So, when you say
something is "looped", you may want to clarify what you mean because
facilities with hearing loops are not as common as you might think. This
article will: review the rationale for ALDs; outline the advantages and
disadvantages of hearing loops; list types of hearing loop installations;
and present considerations for programming the telecoil response in the
hearing instrument.

American Academy of Audiology (Academy) in Crystal City, Virginia, from
June 18 through June 20, 2011. The conference was a culmination of the
year-long "Get in the Hearing Loop" campaign spearheaded by HLAA and the
Academy. The event offered an international, highly public platform "to
enlighten and excite consumers, as well as audiologists and other
professionals who dispense hearing aids or provide services to individuals
with cochlear implants, about telecoils and hearing loops and their unique
benefits." The conference was noteworthy in many ways.

The home of America's top beach could also soon be
the most hearing-friendly city in the nation. Using a grant from the Selby
Foundation, 10 performing arts venues in Southwest Florida will install
"hearing induction loops" that should vault the region to the national
forefront of friendliness to the hearing impaired. Seven other local
organizations - including three churches, a senior center and a library -
also announced plans to install systems outside of the grant funding. With
110,000 people - roughly 16 percent of the population - of Sarasota and
Manatee counties suffering from a hearing loss, the region has one of the
highest hearing impairment rates in the nation.

For a decade or so, a growing band of advocates
has been moving, slowly but steadily, toward its goal of "looping
America." Their vision is to have induction loops installed in public
venues all over the country, so that people who use telecoil-equipped
hearing aids and cochlear implants will be able to hear and communicate
effectively in noisy places despite their hearing loss. This looping
technology, which enables hearing aids to receive only the sounds coming
directly from a microphone without the background noise, has been around
for decades. While it is widely available in Scandinavia and Great
Britain, it has been slow to catch on in the U.S. However, the looping
movement got a major boost this week when a lengthy article in the October
24 New York Times, entitled "A Hearing Aid That Can Cut Out All the
Clatter," gave this technology the kind of positive publicity that no
amount of money could buy. In the article, which was summarized that same
day in the blog AARP News, Times reporter John Tierney led with the
powerful story of a composer, Richard Einhorn, who had suddenly suffered a
severe hearing loss last year at the age of 57

It's ironic and somewhat unfortunate that the
special feature that has the potential to provide the most benefit for
many patients is one that often receives the least attention. In fact,
it's entirely possible that the same audiologists who are concerned about
the best DNR, directionally and feedback reduction systems might not even
include telecoils in the majority of hearing aids that they dispense. The
"potential benefit" I'm referring to is the use of telecoils with hearing
loops. These loops could be installed somewhere as simple as the patient's
living room, or made available in public listening locations like banks,
hospitals, airports, auditoriums, places of worship and taxis. The list
could go on and on (and maybe some day it will). All the patient needs is
telecoils in his or her hearing aids. For a variety of reasons, the U.S.
is far behind many other countries in the use of hearing loops. But
hopefully that is changing. One person who is making it change, room by
room, in her part of the world is this month's 20Q guest author.

next or listen to the tour guide explain the history of an area. No longer

company in the United States to install hearing loop technology in a motor
coach. "Why should hearing loss prevent you from enjoying a motor coach
trip?" asks Jeff Deason, sales director for Indian Trails. Hearing loops
transmit audio signals via a magnetic field created by a wire that loops
around the interior of the coach. The transmitter is attached to the
audio/video system.

It's always interesting to see old technology
become new again. We see it daily in our lives, but I'm referring to a
specific type of old tech; hearing loops. The technology, which is
correctly known by the name of inductive loops, has been in existence for
decades. Based on Faraday's law of induction, a magnetic field is created
and individuals that have a Telecoil (t-coil) equipped hearing aid, can
receive audio signals directly in their hearing aid. A "loop" is a
relatively low-tech solution. In simple terms an area is surrounded
"looped" with a piece of copper wire.

While the United States tends to be on the cutting
edge of new technologies, sometimes it pays to looks to other parts of the
world for the latest advances and ideas. The audiology profession is no
different.
When Juliėtte Sterkens, AuD, originally from the
Netherlands and currently residing in Oshkosh, WI, started introducing and
popularizing hearing loop technology in her community, many people thought
they were seeing the latest advance to help individuals with hearing loss.
But in reality, the idea had been around for quite some time.
"I was learning about this in in my studies--back
in the late 1970s--in the Netherlands," says Dr. Sterkens.
But it wasn't until October 2008 that Dr. Sterkens
realized hearing loops would not only be good for her patients; they also
make great sense from an audiology practice point of view. Today, Juliėtte
combines her audiology experience with the engineering background of her
husband, LeRoy "Max" Maxfield, to bring hearing loop technology to the Fox
Valley in Wisconsin.

For about four years, the Rev. Christine Chakoian
recalls hearing nothing but gibberish when members of her north suburban
Presbyterian church rose to ask the congregation to pray for them on
Sunday. Cut off by a combination of the sanctuary's acoustics and a
typical hearing aid that blurred sounds traveling a distance, the Rev.
Chakoian wouldn't know what to pray because she couldn't understand what
was said from the pews. The disconnect not only undermined the Rev.
Chakoian's connection to her congregation at First Presbyterian Church of
Lake Forest, Ill., but it weakened her relationship with God. "In the
Presbyterian church the word of God is the center of worship. If you can't
hear the word, you're shut off from worship," she said. "You're there to
be part of the community of faith. To not be able to participate in the
community is worse than not being there at all." That changed a year ago
when the Lake Forest, Ill., church adopted the equivalent of Wi-Fi for the
hearing-impaired, otherwise known as a hearing loop.

This is TALK OF THE NATION SCIENCE FRIDAY. I'm Ira
Flatow. Do you ever walk through a train station or airport in Europe or
visited a cathedral there? You may have noticed one of the many blue signs
of a human ear with the words hearing loop installed written underneath.
The signs are a cue to the deaf or to hearing impaired, flip a little
switch on your hearing aid and you can tune it to specially broadcast
announcements sent directly into your ear, kind of like Wi-Fi for hearing
aids. For those with hearing problems, it can make hearing a totally
different experience. The technology is relatively cheap, it's simple, but
even though an estimated 36 million Americans have some level of hearing
loss, it doesn't seem to have caught on here in the U.S., at least not
yet. Joining me now to tell us more about hearing loops and how they work
is a man who is pioneering an effort to get them installed everywhere.

Getting around on the New York subways just got a
lot easier for hard-of-hearing passengers. That's because station
information booths are now fitted with "hearing loops" thanks to the
efforts of Janice Schacter, chair of the Manhattan-based Hearing Access
Program, and funds from President Obama's stimulus package. "We had a
shovel-ready project that fit the criteria," says Schacter. Much as a
Wi-Fi network delivers wireless Internet access to computer users in
coffee shops, a loop system takes sound from an electronic source, such as
a microphone or TV, and delivers it directly to a hearing aid, right into
a listener's head. Hearing loops are relatively simple to install. The
loop is created when a wire is installed around the perimeter of the room
or subway car and plugged into an audio source. That wire then sends a
signal to a tiny copper coil that's now standard in most hearing aids.
(Older hearing aids can usually be retrofitted for about $250.)

users hear conversations by amplifying speech over background noise. The

The development of modern digital hearing aids has
introduced wonderful new possibilities to help hearing-impaired people.
Fittings and set-ups are easier, amplification is powerful and handling
has become more convenient. It is safe to say that the hearing aid has
been the most important tool for hard-of-hearing people for decades and
will be so for the foreseeable future.
However, there are numerous situations where a
hearing aid is not sufficient for all listening needs and where an
additional system may be needed. Wherever there is a high background noise
or a long distance to the signal source, the signal-to-noise ratio runs
too low and problems in hearing become evident. In places like churches,
concert halls, theaters, cinemas, conference rooms, school classrooms,
work situations, and sometimes even in homes, it can be hard to hear with
only the assistance of hearing aids.

For
Americans with hearing loss, the inclusion of telecoils in all hearing
aids and the looping of America would double hearing aid functionality,
increase hearing aid sales and patient satisfaction, and, most
importantly, enable those of us with hearing loss to hear in countless
situations where we now experience uncertainty and stress. . . . imagine
yourself as a person with significant hearing loss. While seated at the
theater or at worship, or standing at a ticket window, you find yourself
struggling to hear. Which of these hearing solutions would you prefer?
Would you want:
1. To take
the initiative to locate, check out, wear, and later return special
equipment (often a receiver with a headset or earphones that are likely
incompatible with your hearing aids), or
2. To push
a hearing aid or cochlear implant button, turning your own hearing
instrument into a wireless loudspeaker that broadcasts sound customized

The Adult Loss of Hearing Association is looped,
and it wants you to get looped, too. That's not a reference to holiday
overindulgence. Rather, the group would like to see more public places -
and private homes with hearing-impaired residents - install induction
looping technology that sends out a wireless signal to certain hearing
aids or to portable headsets. When someone is "in the loop," he or she can
hear speech clearly because sound is being delivered directly from the
source, be it a television or a live person, without any background noise.

Standard hearing aids capture sound via a
microphone and then send an amplified version to an earpiece. They work
well in relatively quiet, intimate settings, but in public spaces filled
with background noise, most users find them of little use. A simple
technology that sidesteps the problem, long available in Europe, has
finally begun entering the U.S. market. Advocates hope that with the
success of pilot projects, the hearing impaired will be able to find
public address announcements and other kinds of speech more intelligible.
The technology is an induction-loop system (known as a hearing loop),
whereby electromagnetic waves produced by a microphone, public address
system or telephone receiver induce an analogous current in the loop. The
loop can broadcast the signals directly to a hearing aid equipped with an
appropriate detector-specifically, a tiny copper telecoil wire, which
picks up the signal (also via induction) and then sends it for
amplification and transmission out of the earpiece.

wireless methods of getting sound to folks with hearing loss. It was

Whereas standard behind- and in-the-ear hearing
aids work well in relatively quiet, more intimate settings, these devices
often lose their effectiveness in larger, public spaces where background
noise puts the hard of hearing at a disadvantage. Although the technology

Increasingly, we are living in a wireless world.
We can make and receive telephone calls while walking down a city street;
we can listen to music while jogging in a park; we can e-mail, text, and
compute anywhere from the airport to the zoo. No longer are we tethered to
desks, phone booths, and electrical outlets. We are free to wander
wirelessly through the array of electronics this world provides. Unless we
wear hearing aids. For all too many consumers, wearing hearing aids
precludes wireless clarity when using a digital mobile telephone or
listening to music on an MP3 player or attending a concert or lecture or
even watching a television program at home. But what if hearing-impaired
people could hear music, lectures, TV programs, and telephone conversation
wirelessly through their own hearing aids-devices that are customized and
programmed to amplify according to each person's individual hearing loss?
Imagine moving through the day, from activity to activity, environment to
environment, taking advantage of the latest generation of electronic
devices without need for neckloops, headsets, or other such devices. We're
not there yet, but the first steps have been taken. And based on research
currently under way, the day of easy, wireless connectivity for wearers of
