The different hearing aids

Hearing aids are devices for the correction of hearing loss’It is a hearing aid for people who are deaf or hard of hearing. The models available vary according to the manufacturer and the specificities of the hearing loss. What are the different types of BTE?’Hearing aids that exist ?

Such as the’It can be seen on, most hearing aids s are made up of’a more or less discreet case, of various colors and often sealed to the ear like a plug’water. The functioning of the device is based on the activity of the hearing aid’s activity’a built-in microphone that The ear picks up and transforms sound waves into electrical waves.

These are filtered and amplified by an amplifier, then converted into sound waves transmitted by a speaker. The latter carries them to the auditory canal thanks to an elbow connected to a plastic sheath. They are then transmitted to the eardrum of the wearer.

In addition, there are different families of in-ear hearing aids’in-the-ear type hearing aid:

  • l’in-ear CIC,
  • l’in-ear IIC,
  • l’in-the-ear IT,
  • l’ITC in-the-ear hearing aid, etc.

These denominations are linked to the characteristics of each model. L’The CIC (Completely In The Canal) hearing aid is the best known and most popular. It s’is inserted entirely in the auditory canal, which makes it almost invisible.

It is particularly suitable for elderly people who want an in-the-ear model.

L’micro BTE hearing aid with a remote earpiece has almost the same characteristics as the ITC BTE’ear BTE. The fundamental difference lies in the connection between the housing behind the hearing aid and the ear canal’ear, and the’in-ear monitor. In the case of the CIC micro BTE’In the case of the micro BTE, this connection is provided by a wire connected to an earphone inserted in the ear canal.
