Styles of Hearing Aids
As hearing instrument technology has evolved, we have become experts in fitting digital hearing aids. We recommend the aids that are the best for your hearing loss and lifestyle, and fine tune your new aids for clear conversation and comfortable, natural sound quality. Hearing aids are only recommended after a thorough examination has been completed and any underlying medical condition that may exist is ruled-out.
CIC
(Completely in the Canal)
This is the smallest type of hearing aid made and in
some ears, is almost invisible. All the components are housed in
a small case that fits down into the ear canal. People often
like this style because it is less visible and “hides” in the
ear canal.
The advantages of this style is that the hearing aid utilizes the ear’s own natural sound collecting design (Pinna or outer ear) to collect and funnel the sound down to the hearing aid. The CIC aid also allows for normal telephone use most of the time and protection from wind noise as the microphone is recessed in the ear canal.
AudioSync iSync
iSync lives in the second bend of the ear for complete
invisibility and enhanced audibility.
ITC
(In the Canal)
A little bigger than the CIC, the ITC hearing aids also
fit far into the ear canal. Canal hearing aids use a slightly
larger battery than the CIC style. This style is used for mild
to moderate hearing losses. It has the advantage of fitting
deeply into the ear canal but may be more manageable by someone
with reduced hand and finger dexterity.
These sizes can also accommodate directional microphones (in most cases) which help focus the sound in front of the patient and minimize the noise along side or behind the patient. No volume controls are necessary in the ITC unit and different noise programs can be accessed by pushing a small button on the faceplate of the device.
ITE
(in the Ear, Full Shell or Half Shell)
These hearing aids can be used for a wider range of
hearing losses. Due to their larger size, ITEs can accommodate
larger sound amplifiers and more features such as directional
microphones and a memory program button.
Directional microphones help the patient focus on the sound in front and minimize the sound on the sides and behind the hearing aid listener. The memory button allows the hearing aid user to access multiple memories that process the incoming sound differently. They are also easier to handle.
BTE
(Behind the Ear)
In BTE hearing aids, the electronics are housed in a
case that fits behind the ear. Tubing and a custom made earmold
direct the sound to the ear canal. Due to its robust design,
this style is especially recommended for children.
BTE hearing aids can provide more amplification than smaller devices due to the stronger amplifier and the larger battery. This style is available in several colors for hair and skin tone matching. The behind the ear unit can also be equipped with directional microphones to help focus the sound in front of the person and minimize the sound beside and behind the person. The units also can have multiple memories included in the design, so that the user can go to a different noise program (via a button on the unit) that reduces background noise and makes speech easier to understand in certain listening environments.
Open
Ear Technology
For millions of Americans with mild to moderate high frequency
hearing loss, new “open Ear” technology offers many advantages
over traditional hearing aid fitting approaches. Typically older
technology would block the normal hearing ranges while trying to
boost the high frequency regions (2 to 6kHz). The result left
the hearing aid user with a plugged up sensation that made
wearing hearing aids almost intolerable.
In the world of open fittings, true useable gain is the foundation of speech intelligibility. A very small thin tube delivers digitally processed sound to the eardrum from a small processor located behind the ear. This type of fitting, keeps the ear open to lower-pitched sounds that don’t need amplification. Help can be delivered to the high frequency consonant regions because acoustic feedback can now be better controlled by digital feedback suppression routines that are the hallmark of “open fitting” technologies. The small processor and thin tubing is cosmetically appealing and the improved clarity, especially in the presence of background is a welcome benefit.
Body Aid
Body aids are the strongest of any hearing aids. A separate
amplifier is clipped to a belt or shirt pocket and then a cord
leads to a button type receiver in the ear. The separation of
the microphone and receiver allows the user to turn up the unit
a lot higher before feedback (whistling noise) occurs.
