All About BTE Digital
Hearing Aids
People who are in the market for hearing aids
can get aids that fit in and on different parts of the ear.
They can obtain hearing aids that have different kinds of
circuitry. BTE digital hearing aids combine a common type of
hearing device with the latest circuitry.
For years, there was no such thing as digital
processing. Then, when there was, it was too big and bulky to
be feasible to be used. Even when it became possible to use,
it still wasn't practical until the technology came along to make
the circuits tiny like they are today. BTE digital hearing
aids are one type of hearing aid that uses this
technology.
What Is So Special
About BTE Digital Hearing Aids?
BTE stands for behind the ear. BTE digital
hearing aids have the same basic structure as ordinary BTE
aids. They have an ear mold that fits into the ear.
This is connected to the hearing aid, which sets behind the ear, by
a tube called the tone hook. A microphone sits atop the
hearing aid to channel sound into the aid. The BTE aid is
durable, powerful, and has easy to use controls.
BTE digital hearing aids are capable of so much
more than the analog variety. If you've ever listened to a
vinyl record album and then a CD, then you are aware of the
difference digital sound can make. However, that's only the
beginning of what a BTE digital hearing aid can do.
BTE digital hearing aids function by converting
the sound that is gathered by the microphone into bits, computer
bits that is. These bits are processed at an amazingly fast
rate. They are used in a processor known in the hearing aid
industry as a DSP, or digital signal processor.
These DSP's are capable of sorting sounds into
channels of frequencies. This is important because certain
speech sounds are higher in pitch and other sounds are lower.
If you don't have the full range of audible frequencies, speech
will sound jumbled to you because you are not hearing all the
sounds. BTE digital hearing aids also have more power for
amplification to make it even easier to distinguish
voices.
BTE digital hearing aids can treat continuous
noise differently that they process short duration noises. It
only makes sense that, for instance, you would be more interested
in the sound of the doorbell than in the sound of the air
conditioner running. They also minimize feedback by both
their circuitry and by the way the ear mold fits into the
ear.
Another problem BTE digital hearing aids correct
is recruitment. This is when a person with hearing loss has
trouble because soft noises sound too soft and loud noises sound
too loud. The digital processing of sound diminishes this
problem. Some BTE digital hearing aids offer two microphones
to focus on what is in front of the wearer. This is called
directionality. It allows for less distraction from the
surrounding environment.
BTE digital hearing aids offer the both
worlds. They are rugged and easy for even a child to
use. They also have the advantages of digital sound
processing. For many, it's an easy choice.
