Hearing Aid Styles
Individual Solutions for Every Individual
There are five basic styles of hearing aids for people with hearing loss.
Click on the hearing aid styles below for a description of each, along with
the pros and cons of each type, and for whom they are best suited.
Behind-The-Ear (BTE)
In-The-Ear (ITE)
In the Canal (ITC)
Completely-In-Canal (CIC)
Open Fitting
Behind-The-Ear (BTE)
This type of aid consists of the device itself which sits behind
the ear, a custom ear mold which sits inside the ear, and a small clear flexible
tube that connects the aid to the earmold. Some of the pros and cons
are as follows:
Advantages:
- This style can be fit to the widest range of hearing losses.
- It can come with a larger number of features than other styles.
- It has larger batteries and controls, making it easier to use for
someone with vision or dexterity problems.
- It has the lowest chance of causing acoustic feedback
or “whistling”.
- It has relatively low visibility, depending on the
hairstyle worn.
- It is larger and harder to misplace.
Disadvantages:
- Requires a little more maintenance than other hearing aid styles because the tubing needs periodic
changing (approximately every six months
or
so) and a new
mold.
- May be more difficult to put on if manual
dexterity is limited.
- May be more visible if the ears are
small or hair is very short.
- Requires slightly different positioning
of the telephone receiver.
Most Suitable For People Who:
- Have severe-to-profound hearing loss or a steeply sloping audiometric
hearing loss pattern.
- Have widely fluctuating hearing
levels.
- Need the additional
features.
- Prefer this aid’s style/appearance to other styles ( TOP ).
In-The-Ear (ITE)
This type of hearing aid and those that follow are housed completely within the
outer ear. There are no separate attachments or other parts behind the
ear. Some pros and cons of this style are:
Advantages:
- No tubes/earmolds to periodically replace.
- Relatively long battery life.
- Can be used with a wide range of hearing losses.
- Can be made with more features than smaller styles.
- The telephone receiver can be held in the usual manner.
- Lowest cost of all in the ear hearing aid styles.
- Easier to place in the ear and change the battery than other smaller
styles.
Disadvantage:
- More visible than other ITE styles.
Most Suitable For People Who:
- Have as much as a moderate to severe hearing loss .
- Prefer its hearing aid style/appearance over that of other models .
- Need the additional features ( TOP ).
In-The-Canal (ITC)
An ITC hearing aid is about one-half the size of the in the ear hearing aid. It can be
used for mild to moderate hearing losses.
Advantages:
- Less visible than the in the ear hearing aid style.
- Still able to get a number of features.
Disadvantages:
- It has a slightly shorter battery life than the behind the ear hearing aid styles and in the ear
styles.
- It may be more expensive than the in the ear style .
Most Suitable For People Who:
- Desire a smaller and more discreet instrument
than the ITE style.
- Have a mild-to-moderate hearing loss ( TOP ).
Completely-In-The-Canal (CIC)
The CIC aid fits completely within the ear canal and is the
least visible of all the hearing aid styles.
Advantages:
- It fits a wide range of hearing losses.
- It is virtually invisible and therefore the most cosmetically
appealing instrument.
- It is the best choice in hearing aids for telephone use because
it has the least chance of feedback.
- The microphone is located in a more natural
sound-gathering position (at or slightly
inside the ear canal opening)
which allows the outer
ear to provide more high-frequency emphasis
and enhanced localization.
- It requires less overall power because of
the close proximity of the receiver
to the eardrum.
Disadvantages:
- It has a somewhat shorter battery life
(5-7 days).
- The smaller battery size may make battery
changes difficult if manual
dexterity is limited.
- Ear wax within the hearing aid can
frequently plug the receiver.
- It may cost more than other
styles.
- Patients may experience more occlusion, a sensation of "talking
in a barrel",
or hearing their own voice as unusually loud.
Most Suitable For People Who:
- Desire a smaller and more
discreet instrument .
- Use the telephone
often and need
amplification for
telephone conversation.
- Want to maximize
the outer
ear’s
sound gathering and localization ( TOP ).
Open Fitting
Open fitting hearing aids are worn behind the ear and have
a clear tube that goes into the ear canal. A probe on
the end brings
the
sound into
the ear canal.
Advantages:
- It works with the natural shape of the ear to amplify
sound.
- Because it does not plug up the ear canal, it
sounds more natural.
- It is less conspicuous than most other styles
and more comfortable.
- Patients can use the telephone without
any problems.
Disadvantages:
- It may cost more than other styles
Most Suitable For People Who:
- Have a high frequency hearing loss.
- Desire a smaller and more discreet instrument.
- Use the telephone often and need amplification
for telephone
conversation.
- Are bothered by the occlusion effect ( TOP ).
