hearing aids

Hearing aids are intended to improve hearing. A distinction is made between two groups:

  1. Behind-the-ear devices (BTE) are worn behind the auricle. They amplify the sound in the external auditory canals. Since the auditory canal is open, a natural hearing sensation and good ventilation of the ear is created. In addition, there is usually an interface to telephones or FM systems. These devices are suitable for severe hearing loss.
  2. In-The-Ear (ITE) devices fit completely in the auricle and the ear canal. They are hardly noticeable and are not a problem for people wearing glasses. They also offer good directional hearing and natural sound. Due to the different ear shapes, however, the devices have to be custom-made and there is a risk of ear canal blockage. These devices are suitable for mild to moderate hearing loss.

Here you will find only an exemplary extract from the hearing aid market. You will find a larger overview in the GKV aids directory in product group 13.

Today's devices work digitally: the sound picked up by a microphone is converted into a digital signal and amplified. Finally, a loudspeaker transmits the amplified sound via an earpiece to the eardrum. Hearing aids require batteries, and they are rarely offered with rechargeable batteries.

The fitting by the hearing aid acoustician plays a major role in the provision of hearing aids. They carry out audiological measurements, adjust suitable devices individually to the hearing loss and offer them for testing in everyday life.
