Now Hear This!
This program was designed as an instructional tool for 4th through 6th grade
mainstream classes. It explains how the ear works and gives general information
about hearing loss, different types of amplification and strategies for communicating
with people with a hearing loss. It can be incorporated into a science unit on the ear
and hearing, or it can be a conversation starter in a classroom where one or more of
the classmates has a hearing loss or uses an assistive listening device. The program
also allows for students to explore, read and complete the activities as a group or
independently.

What is hearing loss? Why does it happen?
When someone has a hearing loss, it
means that they have difficulty
hearing some or all sounds.
Depending on the degree of hearing
loss, a person may be able to hear
some sounds. A deaf person is
someone whose hearing is severely
limited.
Hearing loss can happen for lots of
reasons. Some people are born with
a hearing loss. Some hearing losses
happen after a serious accident or
illness. Sometimes, older people, like
grandparents, develop a hearing loss.
Occasionally, hearing loss can
happen after listening to a very loud
sound, like an explosion. Once
someone has a hearing loss, their
hearing usually does not return to
normal.
Kinds of Amplification
Amplification means a device that makes sound louder. People with hearing loss
have a few different kinds of devices that will make sounds louder so they are easier
to hear. Click on a picture to learn more about the different kinds of amplification.

Listening Device
Cochlear Implants
Some deaf people are not able to hear, even
when they wear the most powerful hearing
aids. Sometimes they decide to get a cochlear
implant to help them hear.
A cochlear implant is a special device that is
inserted in the cochlea, in the inner ear. The
cochlear implant sends a sound signal from a
speech processor that the person wears, either
on their ear or in a fanny pack on their waist,
directly to the cochlea and up the auditory
nerve to the brain.
For many people, cochlear implants help them
hear many sounds that they otherwise could
not hear. Click the picture to hear how it
sounds to listen with a cochlear implant.

Hearing Aids
Hearing aids come in lots of shapes
and sizes. Some people have one
hearing aid, and some have two.
Whether they are the kind worn
behind the ear or the tiny hearing
aids that fit inside the ear, all hearing
aids make sound louder and easier
to hear.
Hearing aids have a microphone on
them that pick up all the sound from
the environment. Then, inside the
hearing aid, the sound is changed
and made louder. Then it travels out
of the hearing aid and directly into
the ear of the person wearing it.
Assistive Listening Devices
Assistive listening devices work kind of like a radio.
There are two parts: a transmitter (microphone)
and a receiver (ear piece or speaker.) The
transmitter sends an invisible signal through the air,
which is picked up by the receiver. Usually the
teacher wears the microphone, and the students
wearing the receivers hear the teacher’s voice right
in their ears. The signal can even go through the
wall. Sometimes students can hear their teachers
even when they are in the hall or bathroom!
Assistive listening devices help people with normal
hearing as well as those with hearing loss. You
might have seen this kind of device and never
knew what it was. Football coaches and players
use these devices to talk to each other. The coach
can stand on the sideline and speak to the players
without having to yell. TV newscasters also use
listening devices to hear their directors giving them
instructions from the control room.
Hearing Fun Facts
Where would you like to go?
Talking to a person with a hearing loss
DO…
…look right at the person, so
they can read your lips.
…talk with a normal voice
volume. You don’t need to
shout.
…tap the person gently on
the shoulder to get their
attention before you start to
speak.
…repeat what you said if the
person didn’t hear or
understand you.
…ask polite questions if you
are curious. It’s nicer to ask
than to stare.
DON’T…
…cover your mouth while you are talking.
…talk too fast or too slow. This makes you
harder to understand.
…turn your back or walk away.
…be nervous or afraid. Remember, hearing loss
doesn’t change the person on the inside.

Taking Care of Your Hearing
Hearing loss can be caused by things people do to their ears.
To protect your ears, remember the following:
Loud sounds, like music or an explosion, can damage the tiny
hair cells in the inner ear. If you are going to a place where there
will be loud sounds, like a concert or fireworks display, bring some
earplugs along. They won’t block out all the sound and your ears
will thank you for it.
If you need to clean your ears, do it carefully. You shouldn’t stick
anything into your ears. It’s best to use a washcloth and only wash
the outside of your ear canal.
If you get an ear infection, see a doctor right away. Untreated
ear infections can sometimes damage the eardrum or middle ear
bones.
