(((((Wireless))))) Hearing Aids
"Wireless" hearing aids have, in addition to the function of the hearing
aid, a short-range transmitter and receiver.
The main benefits of wireless hearing aids are:
It allows hearing aids to communicate with one another -
example the hearing aid in the right ear can communicate with the
and vice versa;
It allows hearing aids to be connected to other devices, most
It allow the person fitting your hearing aids to
hearing aids without specially designed
HEARING AIDS COMMUNICATING WITH ONE ANOTHER
The "Wireless" hearing aid - is not a new idea. In the late
1970's, Telex introduced an wireless hearing aid for people with
one-sided deafness. The deaf (or unaidable) ear would be fit with a
microphone + FM radio transmitter, which would then send signals to
an FM receiver on the better (aided) ear. The wireless hearing aid
Today's digital hearing aids basically use the same concept but they have
more applications and the signal is no longer FM. Kind of like your home's internet system,
digital hearing aids continuously "stream" information back and forth
between hearing aids to......
♥ Provide true
stereophonic hearing with all of its advantages, including enhanced
word clarity in various listening situations and improving sound
Provide the very
practical benefit to the user to adjust volume or programs* in both hearing aids by adjusting just one side.
This sounds simple, but technically quite sophisticated.
The term "programs"
meaning special hearing aid settings for select situations such as
music, telephone, et cetera, normally controlled by the user.
ALLOWING HEARING AIDS TO BE CONNECTED TO OTHER DEVICES
most people and professionals think of regarding "wireless
hearing aids" is the ability to connect their hearing aids
directly to Bluetooth devices.
This is not the most important feature of
wireless hearing aids and furthermore, wireless
hearing aids are not by themselves Bluetooth compatible.
They require a device that communicates between your hearing
aids and a Bluetooth-compatible device. In the picture to the right,
notice the device the user wears around her neck. This is
paired with a Bluetooth-compatible device (like a cell phone)
and sends signals via short range transmitter to her wireless hearing aids.
PROGRAMMING HEARING AIDS WITHOUT CABLES
feature is not as beneficial to users, it is a very convenient
benefit for practitioners. Nearly all hearing aids are tuned using a PC with proprietary software provided by hearing aid
manufacturers. For this to happen, your hearing aids must
be somehow connected to the manufacturer's software. Hearing aids that are "non-wireless"
must be connected using cables with each model of hearing aid
needing its own set of cables. Wireless hearing
instruments on the other hand, are
connected wirelessly to a neck loop device that communicates
with the computer.
THE DISADVANTAGE OF WIRELESS HEARING AIDS
only disadvantage of wireless technology is the faster drain on
hearing aid batteries. The effect of
continuous streaming of data roaming between hearing aids takes
a toll on battery life. I estimate battery life is 25%
worse, which translate to about $2-3 extra per month.
