The smallest,
least visible model is the Completely-in-the-Canal.
It fits deep inside your ear, where it's hidden in the shadow of
your ear canal.
|
 |
|
The In-the-Canal hearing aid is small
enough to fit almost entirely in your ear canal, occupying about
one quarter of the ear to reduce its visibility significantly.
|
 |
|
The In-the-Ear model is a one-piece aid
custom designed to fit inconspicuously within the outer portion of
your ear. It is the most widely recommended hearing aid style.
|
 |
|
The Behind-the-Ear model fits snugly behind
your ear, and is attached to a custom earpiece molded to the shape
of your outer ear. It is designed for a wide range of hearing
loss.

Circuit Design and
Capabilities
The technical choices in current hearing aids allow the
consumer a variety of options. There are approximately 600 models of
circuit designs with digital programming and digital processing
capabilities, in addition to many non-digital circuit designs. These
circuit choices can be categorized into seven technologies.
- LINEAR CIRCUITS - These make all sounds louder.
- TRADITIONAL COMPRESSION - These soften some loud sounds
when they occur.
- ADVANCED COMPRESSION - There are many special circuits to
make hearing aids more comfortable. Your specialist will guide you.
- ADVANCED DESIGN NON-DIGITAL - These are unique newer more
complex circuits that may be "automatic" (i.e. no volume
wheel necessary).
- DIGITAL PROGRAMMABLE - These higher technology circuits
have 1-13 adjustable bands of compression. Often they are automatic
and use computers to program different listening environments. Some
models use remote controls to provide more direct client control.
- 100% DIGITAL (DSP) - DSP stands for Digital Signal
Processing, audio sounds are digitized and then processed. These
types of hearing aids use computers for the fitting process. They
contain computer chips within the hearing aid for further
processing.
- DEEP CANAL CIRCUIT - For maximum benefit this circuit
depends upon the placement of the hearing aid near the eardrum,
which changes the performance of this type of hearing aid.
