The Classic Hearing Aid: BTE
1. The Classic Hearing Aid: BTE
It's been over 50 years since
Siemens debuted the world’s
first BTE hearing aid. In that
time, the iconic style is the first
image that comes to mind when
most people think of a listening
device. This is due to it's
prominent placement on the rear
of the ear as well the long
standing success of the device in the marketplace.
Behind the ear listening devices debuted in 1959 and have been
continually improved since. While the industry has seen a
proliferation of alternatives, this classic maintains popularity for
several reasons.
For starters, the device's "biggest in class" size allow it to be
outfitted with a full set of controls, such as volume and on/off
switches. This benefit coincides with the power such units are
capable of achieving. They are ideal for those with severe hearing
loss.
While the fashionista in you may abhor the aesthetics of BTE
hearing aids, modern devices are not the clunkers of the
mid-twentieth century. Today's devices are ergonomic and
available in an assortment of colors. A newer style of mini-BTE
units also exist, further decreasing the visibility of the hearing
instrument for the chronically self-conscious.
One thing that hasn't changed about these devices are their
2. composition. Now, like then, each unit is comprised of a case,
which houses the electronics, an earmold that has a tiny speaker
to deliver sound and a tube used to carry sound between the
other components.
Depending on the device you select, behind the ear listening
instruments are more affordable than other styles. This is no
doubt a result of their market maturity and wide availability.
Not only can you get behind the ear units from giants like
Siemens, Starkey and Widex, but they're also available from
more obscure, discount manufacturers on the web.
Unlike larger companies, discount sellers aren't worried about
developing the next generation of cutting edge devices, requiring
millions of dollars in research and development. Likewise, they
don't have large branding or advertising costs. As a result,
discount sellers are able to offer more competitive pricing on BTE
hearing aids.
