Hard of Hearing

The Ear
Just because your ear
does not work
correctly, does not
mean your life has
to stop. With proper
assistance and
devices, you can
“perceive” almost
Closed Captioning
• Open captioning, whereby
written words are displayed on
the screens of all viewers,
provides the greatest access but
presents the problem of
distraction to viewers not
hearing impaired (The
Television Decoder Circuitry
Act, 47 USC §303(u), which
was enacted in 1990, requires
that as of July 1,1993,
televisions that have a picture
of 13 inches or greater
manufactured in
the United States or for sale in
the United States must be
equipped for closed captioning.
Captioning Software
Since 1985, we have been the industry leader in captioning, subtitling, and
teleprompting software. In addition to this state of the art software, we have
added DVD, Webcasting, and V-Chip software to our list. CPC is the choice, Ask
any of our thousands of satisfied customers. CPC has been operating award
winning services since 1989.
CPC is the proud winner of the Federal Distinguished Vendor of Accessible
Technology Award.
CPC is also the winner of the Small Business Administration (SBA)

Hearing Aides
• Aides are made to be worn
in the ear or behind the ear.
• Hearing aides can be digital,
programmable, or analogue
• Prices of an individual aide
range from $500 to $4000
• Most insurance companies
WILL NOT cover the device.
Alarm Clocks
• There are many
kinds of alarm
clocks. Vibrating,
flashing, or
increased decibel
levels are just a few
that are out there.
Cochlear Implant
A cochlear implant is a prosthetic
device that acts as a replacement
for damaged portions of the
cochlea, or inner ear. This device is
used by people who have hearing
damage that is so significant,
conventional hearing aides offer
them little or no improvement. The
cochlear ear implant consists of
several components, some of
which are external to the body, and
others that are internal. To pick up
sound in the environment, a small
microphone is worn behind the ear.
The microphone is connected to a
speech processor, usually worn
inside a pocket, which amplifies,
filters, and changes the sounds into
digital code.
The Cochlear Implant Continued
The code is then transmitted
via a coil to a
receiver/stimulator, located just
beneath the skin near the ear.
This receiver/stimulator
produces electrical stimulation
and sends it to electrodes
which wind into the snail
shaped cochlea of the inner
ear. The electrodes stimulate
the intact nerves in the
cochlea, which can then deliver
the auditory information to the
brain. The following drawing
depicts the internal electrodes
going into the cochlea.
• And just how does a
deaf person
communicate over
the phone?
• The Illinois Relay
Numbers are as
follows: 1-800-5260857(V) 1-800-5260844(TTY).
Auditory Trainers
• Used in school settings
in place of the hearing
aide. Many different
versions are available.
Direct amplification of
the speakers voice is
the focus of this
product. It is important
to shop around for the
right product for your
• Yes, even the deaf can
receive and send
pages instantly
without a phone!
The ICommunicator
The Icommunicator is a
laptop computer that
sits on a student’s
desk. It includes live
captioning of voice
from a microphone
directly on the screen
and also a sign
language interpreter.
Roughly 8 G’s!
Movie Theater Captioning
• Movie Patrons sit
and use a small
mirror which is
portable and
attaches to their
seat. Words are
reflected from a
display screen in
the back.
