CROS and BiCROS fitting
If you are completely deaf, you cannot do a normal hearing aid
use. With such a hearing aid, only the sound is
reinforced and thereby stimulates your inner ear. But that's not enough
more. However, if you can only hear one -sided, you can sound sounds
no longer assign and do not know which direction they come from.
This makes it difficult for them to distinguish background noises. But
There are also special solutions for these cases that listen to you
facilitate. These solutions are individually on your needs
tailored.
This guide deals with the so-called cros- and
Bicros supply technology for your ears. This technique is used
If you are deaf one -sided. It enables them to continue
to be able to hear directional. Your quality of life improves in
effectively.
Directional hearing despite unilateral hearing loss
Despite one-sided numbness

So listen to binaural, then the sound waves get differently strong
to their hearing. The sound waves just take longer to turn the turned away
To reach ears and arrive quieter there. The brain uses this
Information to be able to identify the origin of the sound. So you can
Locate the brain exactly from which direction the noises come. She
So can orient themselves well in the room. A location is then not
Problem, because the exact position is simply heard.
If you are now on one side, then you can sound, sounds and
Always hear voices with the healthy ear. So the brain is the

Change your position. With one -sided numbness, ears and brain are not
able to recognize the direction from which the sound sources
come.
It is very difficult for you as a person affected, a certain sound under
to recognize many diffuse and noisy background noises
to concentrate on it. Conversations are then also a problem for
You.
Different causes of one -sided numbness can
present:
-
Tumor
-
Craniocerebral trauma
-
Congenital impairment
If you are deaf one-sided, you can have a cros or
Bicros supply enable direction listening again. Then recognize
You, for example, when you are approached on the damaged side.
The cros/bicros technology is highly developed. Through them the sounds
which you actually cannot hear, deflect on the hearing ear.
This can take precise processing in your brain. Their life
So it becomes clear with cros and bicros hearing aids
Simplified.
How do cros bicros hearing aids?
With a classic hearing aid, listeners and microphone lie close together.
This increases the signal on the corresponding ear. At a
However, one -sided deafness does not lead to success. For this reason
a completely different concept was developed by the scientists. At
The so-called cros supply are independent of listeners and microphone
attached to different locations.
A microphone picks up the sound on the pigeon ear and leads it
Automatically on to the healthy ear. The listener is located here. The
This technique does not normal listen to your healthy ear
influenced, but the brain can assign it from which direction
The sound waves come.
A few years ago, the necessary technology had to be in one
Glasses are hidden. The microphone on the glasses bracket was
attached and the cable for the transfer of the sound into the frame
incorporated.
In the meantime, the process is very modern and the hardware is very
become inconspicuous. The transmission takes place without cable by
Radio signal. The sound is transmitted quickly and precisely and comes in
functioning ear using otoplasty. Otoplastics are
Hearing pieces that are individually adjusted. To do this, let them first
take over to our hearing acoustician. This then serves
As the basis for the production of your otoplasty, which after the adaptation
Sits perfectly in your ear canal.
The technical equipment of the cros hearing aids can be made from manufacturer

IM-ear hearing aids .
