Identification
Every hearing instrument is unique and can be identified by its serial number. The location differs depending on the type of aid you have—Behind-the-Ear (BTE), In-the-Ear (ITE), In-the-Canal (ITC) or Completely-in-the-Canal (CIC).
BTE
For BTE models, the serial number is located on the battery
door. The manufacturer’s name and the model number can be
found on the inner curve of the hearing instrument.
ITE
ITC
CIC
Why Board Certification?
Some of the most highly experienced hearing health professionals in the world share a distinguishing symbol-the symbol of certification through NBC-HIS. Certificants are fully committed to providing their patients with quality care.
The achievement of this designation represents their initiative to excel beyond the normal requirements for operating a hearing instrument dispensing practice. The designation, BC-HIS (Board Certified in Hearing Instrument Sciences), distinguishes the persons outstanding skills and professional expertise needed for completion of the National Competency Exam.
Insertion and removal
Whether you wear Behind-the-Ear (BTE),
In-the-Ear (ITE),
In-the-Canal (ITC)
or Completely-in-the-Canal (CIC)
models, your hearing instruments are unique to you, and were
made from impressions of your individual ears. They are
designed to fit comfortably and to be easy to insert and
remove. If for any reason they cause you discomfort, see your
hearing professional. In many cases, minor fitting adjustments
can be made in their office or clinic.
Insert and remove your hearing aid according to the
description for your particular model:
BTE
Before placing the BTE earmold into your ear, first make sure
the battery is inserted properly and the battery door is
securely closed. Also make sure the M-T-O switch is set to “O”
(off).
To insert, hold the earmold on the outer side near the tubing with your thumb and forefinger. Gently insert the canal tip of the earmold into the ear canal. Then softly press the earmold into place with your fingertip.
Carefully place the instrument behind your ear with the earhook and earmold tubing wrapped over the top.
To remove, take the instrument out from behind your ear and gently pull the earmold outward. Pulling down on the ear lobe may help loosen the earmold as it is removed.
ITE
Before placing the ITE in your ear, first make sure the
battery is inserted properly and the battery door is securely
closed. If the instruments have a volume control, make sure
they are in the “off” position.
To insert, hold the instrument between your thumb and forefinger with the volume control toward the top of your ear. The battery compartment should be facing away from your ear canal. Then gently insert the instrument into your ear.
Gently rotate the instrument until its comfortably set inside the bowl of your ear. Pull your ear lobe down slightly and press on the instrument to ensure it is firmly in place.
To remove, grasp the instrument with your thumb and forefinger, and gently rotate it as you pull outward. Never use the battery compartment door to pull the instrument out of your ear—it is not designed to withstand this pressure and may become damaged.
ITC
Before placing the ITC into your ear, first make sure the battery is inserted properly and the battery door is securely closed. If the instruments have a volume control, make sure they are in the “off” position.
To insert, hold the instrument between your thumb and forefinger with the volume control toward the top of your ear. The battery compartment should be facing away from your ear canal. Then gently insert the instrument into your ear canal.
There are two methods of removing the ITC from your ear. One way is by using your finger to gently massage the area behind your ear lobe. The soft pressure should work the instrument out of your ear. The other method is to reach into the ear with thumb and forefinger, and gently pull the instrument out.
Never use the battery compartment door to pull the instrument out of your ear—it is not designed to withstand this pressure and may become damaged.
CIC
Before placing the CIC into your ear, first make sure the battery is inserted properly and the battery door is securely closed.
To insert, hold the instrument with the insertion/removal line between your thumb and forefinger, and the microphone opening at the top of the instrument. Simply guide the instrument down into your ear canal until you feel resistance.
Let go of the insertion line, and push the instrument in until it is resting comfortably inside your canal. To ease insertion, you may wish to pull down on your ear lobe with your other hand as you push.
To remove, slowly and gently pull the insertion/removal line outward.
Never use the battery compartment door to pull the instrument out of your ear—it is not designed to withstand this pressure and may become damaged.
Handling and controls
Always keep your hearing instruments clean and dry. To preserve battery life when you’re not wearing your instruments, open the battery compartment doors so the batteries are not in contact with the internal components.
If your instruments have a volume control, use it to turn them on and off and adjust the level of amplification.
To turn your instruments on, rotate the control forward or clockwise until a comfortable sound level is reached. You may want to adjust the volume as you move between different listening situations. To increase volume, continue rotating the control forward. To make sounds softer, rotate the control backward or counter-clockwise. To turn your instruments off, rotate the control backward as far as it will go.
If your instruments do not have a volume control, they are “on” any time functioning batteries are properly placed in the compartments, and the battery doors are closed. To turn your instruments “off,” simply open the battery compartment doors so the batteries are no longer in contact with the internal components.
When any hearing instrument is “on,” you may occasionally hear a whistling noise known as feedback. It’s more likely to occur while you’re inserting or removing your instrument. Feedback is caused by amplified sounds leaving the ear that are reflected by your hand back into the instrument’s microphone. It should stop when you move your hand away. If you have trouble with persistent feedback, see your hearing professional.
WISE EARS AT WORK!
Here are the facts:
Noise-induced hearing loss is the
most common workplace disorder and the second most
self-repeated occupational illness or injury.
Thirty million workers are at risk for noise-induced hearing
loss and 10 million Americans already have it.
Forty-five percent of carpenters and 48% of plumbers report
having a hearing loss.
By age 25, the average carpenter has the same hearing as a
50-year-old person who does not work around hazardous noise.
DON'T LET THIS BE YOU!
Noise-induced hearing loss is 100% preventable, but once you
have hearing loss, you'll have it for life. Exposure to
harmful sounds causes damage to the sensitive structures of
the inner ear. These structures can be injured instantly from
an intense brief impulse, such as the explosion of a
firecracker, or gradually from continuous exposure to noise,
such as in a woodworking shop.
HOW LOUD IS TOO LOUD?
Are you in an area where you have to raise your voice to talk
with someone who is an arm's length away? Are your ears
ringing or do sounds seem dull or flat after leaving a noisy
place? If so, then you are probably exposed to hazardous
noise. The degree of a hearing loss is related to both the
level of the noise and the duration of the exposure. Sound is
measured in decibels (dB). Prolonged (long or repeated)
exposure to noise about 85 dB can cause hearing loss. A normal
conversation takes places at about 65 dB. A hard drill
measures 98 dB, a spray painter 105dB, a hammer drill 114 dB,
and a pneumatic percussion drill 119 dB. If the average level
of noise in your workplace over 8 hours is 85 dB or higher,
you are at risk for noise-induced hearing loss. Start
protecting your ears now!
How can you protect your ears?
The safest way to protect your ears is to always wear hearing
protection anytime you are around loud noises. You can protect
your ears by wearing special earplugs or special earmuffs.
There are hundreds of kinds available. There are formable
earplugs you can mold to your ears and premolded earplugs that
come in several sizes. There are canal caps that are attached
to headbands and are very convenient if you work in
intermittent noise where you need to take your earplugs on and
off throughout the day. Some earplugs have stems so you can
insert them without touching the part that goes inside your
ear. You can also get earplugs custom molded to fit your ear.
Earmuffs come with large and small earcups, and different
types of ear cushions. There is something for everyone and for
every environment. Which type are you getting?
How can you hear verbal instructions or machine warnings?
Hearing protection will lower the noise level of your
equipment, they won't eliminate the sound. There are
protectors that lower the sound enough to be safe but allow
you to hear speech at a comfortable level. This is especially
important for those who work in noise where communication is
important. The hearing protectors will bring both noise and
warning sounds down equally. So, if the warning sound is
audible without the hearing protector, it will usually be
audible when wearing the protectors. Some protectors will
reduce certain frequencies more than others, so wearing them
can make noises sound different. If it is important for you to
hear noises just as they are, there are earmuffs and earplugs
that reduce all sounds about the same. There are many hearing
protectors with built-in communication systems. There are even
special high-fidelity earplugs and noise-activated hearing
protectors that professional musicians (rock and classical)
and mechanics wear. These earplugs and protectors don't change
sound quality except for making it softer. They are useful
when it's important to hear speech.
