ITE (In-The-Ear)
In-the-Ear devices are a custom made product that fills the concha (the bowl of the ear) and
some portion of the ear canal. A broad range of circuit designs are available that allow these
devices to be used in individuals with a mild to severe hearing loss. These devices are easy
to manipulate for those with poor vision or manual dexterity problems.

ITC (In-The-Canal)
These devices are smaller than ITEs and fit only in the outer portion of the ear canal. ITCs are
suitable for patients with an adequate sized ear canal, mild-to-moderate hearing loss, and no
moisture or skin problems of the ear.

CIC (Completely-In-The-Canal)
This is the smallest device available and is cosmetically desirable because it fits deep in the
canal and takes advantage of the ear's natural resonance and shape. Most patients are able to
use these hearing aids with the telephone without experiencing feedback. CICs require good
manual dexterity, a normal outer ear canal and no medical conditions that would prevent their
use. CICs require a precise fit as they are seated deeply within the ear canal. Digital CICs
are generally the most expensive amplification devices available due to their size and advanced
technology.

BTE (Behind-The-Ear)
The Behind-the-Ear (BTE) device consists of an instrument that rests behind the ear
attached to a custom made ear mold. This style may be used for all types and degrees
of hearing loss. These devices can be packaged in a mini case depending on the type
and level of hearing loss. A BTE device may be required due to medical conditions of
the external auditory canal that prohibit the use of other devices.
