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 seriniti.fr, 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.

Nevertheless, its quality-price ratio is very satisfactory. Low-end models cost around 500 euros, while the most powerful ones cost around 1,300 euros.

However, its use depends on the size of the patient’s ear canal.

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.

The ITC (In The Canal) model is relatively more voluminous. Nevertheless, its autonomy is better because’it is equipped with’A larger battery. On the other hand, the’The IIC is the smallest of all. It is therefore the most discreet.

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

The micro BTE’A hearing aid adapted to all profiles

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.

This type of hearing aid is’combines performance and discretion thanks to this particularity. It allows, among other things, to correct hearing losses of up to 10 dB’at 80 dB.

Beyond this value, it will be necessary to adapt a special earmold to it. Also, the acoustic signals produced are directly delivered by the’The micro earpiece installed in the ear canal.

They can also be equipped with advanced features such as Bluetooth connectivity.

However, this type of model does not have the same characteristics as the BTE’It is not recommended for severe hearing loss’hearing. It is used for the drops of the’Light and moderate hearing. Its discretion is also limited compared to the in-the-ear device. In fact, the connecting wire is always visible, especially if the wearer has short hair.
