Hard of hearing people often struggle to catch television's
fast-paced dialogue. Captioning is a great help, especially
for prerecorded entertainment programs (on which captioning
is usually simultaneous and accurate). Still, hearing is preferred
to reading captions--and both are better than captions alone.
Most people with hearing loss have a simple way to cope with
the challenges of TV listening: they turn up the volume. This,
however, has two problems: 1) the sound they find most comfortable
tends to be irritatingly loud to their spouses and family
members, and 2) louder sound needn't, after traveling the
distance from the TV to one's ears after reverberating around
the room, be clear sound.
Infrared, FM, and induction loop systems all enable people
with hearing loss to hear clearer TV sound--and, to their
family members' relief, with their own individually adjusted
volume. (One such product has been called "the marriage
By broadcasting through one's own customized hearing aids,
loop systems work especially well. Moreover, one needn't fuss
with wearing a receiver contraption or stocking fresh batteries.
Better yet, if desired one can also hear room sound, including
conversation and a ringing phone or doorbell. This is accomplished
either by using MT (mike + telecoil) settings on one's hearing
aids, or by patching an accompanying microphone into the loop
amplifier. (Some TV room loop systems come with a microphone
that broadcasts room sounds along with TV sound.)
This is one loop installation that can often be done without
a professional. Just plug the amplifier into a power source,
connect it to the TV audio output, and run its wire around
the edge of the room and over the doorways or under the carpet--or
drop the wires to the basement below and use a staple gun
to encircle the TV room from the basement ceiling. The amplifier
will have a volume control. Some home loop systems also package
the loop in a thin pad that slips under the cushion of one's
favorite chair. No fuss! Just run the connecting wire around
to the amplifier, into which one can patch TV or a microphone.
For an excellent installation guide, see here. Dr. Neil Baumann offers a helpful PowerPoint guide to home loop installation here. He also offers (here) suggestions for purchasing a TV with audio outputs that will work nicely with a home loop system, and also work-around suggestions if you have a TV without the preferred configuration.
California audiologist Bill
Diles now offers home loop installations to all his
hearing instrument patients--some 1900 installations by early
2012. The results: The patients reported not only greatly
increased TV satisfaction, but also greatly increased satisfaction
with their hearing aids.
By also patching telephone output into a home TV loop system,
people can enjoy dramatically increased comprehension--with
personalized sound broadcast to both ears--while talking naturally
on the phone, without any clumsy wires or headsets. This works
beautifully. Radio Shack offers a connector
for recording conversations that can, instead, be patched
into a home or office loop amplifier. Happily, it has an on/off
switch, so one needn't eavesdrop on others' conversations
while watching TV. (Either one splits your phone signal, with
one line going to the phone or handset, the other to the loop
