Hearing Aid Styles
Realize that any circuitry can be put into any style/size of hearing aid. Each
size has its benefits and detriments. Larger style aids provide better access
to manual "options" that can be available with the different types of circuitry,
but there are trade offs for this access. By the same token, smaller style aids
may not have the same access to options, but can be more versatile for the active
individual. The appropriate style can be determined in close consultation with
your audiologist and by examining your hearing loss, lifestyle and individual
hearing needs and circumstances.
Behind the Ear
(BTE) |
Appropriate for all degrees of losses. Best for severe
to profound hearing losses. |
|
Pros:
- Durable
- Least Expensive
- Room for manual controls
- Longer battery life and larger batteries
|
Cons:
- Telephone switch needed for use with phone
- Higher exposure to wind noise
- Reduced directionality
- Need to replace tubing every 3-6 months
|
| In the Ear (ITE) |
Appropriate for all degrees of hearing loss. Works well
for those with severe hearing losses who desire an “in the ear” instrument. |
|
Pros:
- Durable
- Least expensive (cost comparable to BTE)
- Room for manual controls and options
- Longer battery life with larger batteries
|
Cons:
- Telephone switch needed for use with phone
- Higher exposure to wind noise
- Reduced directionality
- Aid fills entire ear
|
| In The Canal (ITC) |
Appropriate for mild to moderately-severe hearing impairments.
Not appropriate for profound losses. |
|
Pros:
- Custom aid sits in “bowl” of ear
- Telephone switch option but not necessary
- Reduced chance of wind noise
- Less visibility
- Battery life 7-12 days
|
Cons:
- Shorter battery life compared to larger aid
- Reduced space for manual options/controls
- Potential dexterity problems
|
| Completely In Canal (CIC) |
Best suited for mild to moderately-severe hearing impairments. |
|
Pros:
- Custom aid sits deeply in canal – least visible
- Low chance of problem due to wind noise
- Phone switch not necessary
- Battery life 5-7 days with smaller batteries
|
Cons:
- Shorter battery life
- Potential for repairs due to neglect
- No manual control options
|
Hearing Aid Options
Hearing aids are exactly what the name states, an aid to assist you in hearing.
It is meant to improve your hearing, not correct it. In its simplest form, the
hearing aid is simply a microphone, amplifier, and loudspeaker system, fit into
the size of a nutshell. You may ask: “Why does it cost so much if that's all
it is?” Imagine your whole high-end DTS 7.1 THX home entertainment surround
sound system (minus the nest of cables) fitting in your ear… Suddenly a hearing
aid becomes far more impressive. Obviously something is lost in size reduction,
but even the simplest hearing aids have amazing cutting-edge technology that
warrants appreciation. In a hearing aid, the technology is independent of the
size of the aid. It can be grouped in three main categories:
Hearing Aid
Circuitry Options
- Conventional: your standard hearing aid system that has stood
the test of time. The person fitting your hearing aid adjusts most through
the use of trim pots accessed with a small screwdriver. The hearing aid’s
automatic response is at best limited so volume adjustment is manually accessed
through a volume control. It is a very appropriate circuitry for someone
who is almost exclusively home and just needs assistance hearing family
members, the phone or the TV. Limitations occur if the person has dexterity
or cognitive problems that limits their ability to manipulate the volume
control or telephone switch.
- Programmable circuitry: Often confused with the digital hearing
aids, programmable circuitry is a hybrid between the conventional circuitry
and the digital. The circuitry is similar, but generally more advanced than
the conventional with one important difference, a computer chip is now coupled
to the circuit, allow direct access and more precise manipulation of the
hearing aid response to sound at the fitter’s location! It allows the hearing
aid a more automatic response, many times eliminating the need for a volume
control unless desired by the patient and a increased options for hearing
aid response including multiple memories to address the issue of background
noise and directional microphone arrays. It is the opinion of many professionals
that this will soon become the standard for hearing aids if it has not become
so already.
- Digital circuitry: The top of the line of hearing aid circuits.
The difference between the digital versus the programmable is all in the
computer chip placement. While before the computer chip was coupled to the
circuitry, with the digital, it is at the beginning of the circuitry resulting
in the acoustic signal to be translated into computer “binary” code. This
allows more precise control over the sound processing resulting in a cleaner
sounding, faster responding instrument. It still is not normal hearing,
but to many, the sound quality is much improved and the faster acting response
allows them to “forget” about the hearing aid enough to feel comfortable
encountering various noise situations without worry. It is a very appropriate
circuit for people who enjoy an active lifestyle that results in diverse
environments, meetings, or business people who do not wish to “fuss” with
the hearing aid but wish the clarity of sound.
Assistive Listening Devices
We also feature selection of assistive listening and alerting devices to improve
communication and listening skills for specific situations. These include FM
Systems, TV Infrared Listening System, Clarity telephone, Pocket Talker personal
amplification system, Shake Awake alarm clock, and Alertmaster Systems (for
alerting to doorbells, crying babies, etc).
Other products include batteries, accessories, ear protection, swim plugs, musicians'
ear plugs, shooters plugs, pilot partners.
