 Advances in digital technology have dramatically
improved hearing aids. They are now smaller than ever
before with far better sound quality. Top-of-the-line
models feature "directional" or "high definition"
hearing. These devices use two microphones and an
algorithm to enhance sound coming from the front (the
person you are talking to), while tuning down sound
coming from behind (background noise).
Beltone’s state-of-the-art digital hearing aids include:
-
Multiple channels for better
prescription fit
-
Automatic volume control to
ensure sounds are never too loud and are reduced for
comfort.
-
Speech Pattern Detection and
noise reduction to help you hear better in
background noise
-
Anti-Feedback Control to reduce
whistling
-
Wind Noise Suppression to help
you better enjoy outdoor activities
-
Open fit technology to relieve
feeling “plugged up”
Hearing Aid Basics
Sound waves enter through a microphone, which converts
the acoustic signals into electrical signals. An
amplifier increases the strength of the electrical
signal. From the amplifier, the signal is transformed
back to an acoustical signal by the receiver (a mini
loud speaker). From the receiver, the signal is
channeled onto the ear canal, either through a small
tube or an ear mold.
There are two main styles of hearing aids.
-
In-the-Ear (ITE) hearing aid
ITE hearing aids fit directly into the external part
of the ear and are custom made to fit the contours
of your ear. Appealing shell styles combine improved
cosmetics with optimal power and sound quality.
-
Behind-the-Ear (BTE) hearing
aid
BTE hearing aids are housed in a small curved case
which fits behind the ear. A thin transparent tube
is inserted directly into the ear canal. This
reduces the “plugged up” sensation associated with
some hearing aids. This type of hearing aid is also
referred to as “open fit” since your ear canal is
left open.
