There are three major families of hearing aid devices that can help the hearing impaired in sound perception. The hearing aid is usually composed of a microphone, a headset, a processor, and a battery. The major families of devices differ in particular with their functionality and the settings of the device.
The earloops
This model is most popular with the hearing impaired. It offers a lot of benefits for people touching hearing problems. The earloops have a system allowing access to different powers. They adapt to all levels of hearing loss. Moreover, the manipulation is favored by their size. The batteries can last up to 10 to 15 days especially for a use of 12 hours a day. Aesthetics is certainly the only design of this type of device.
In-ear
This type of device is the second form of hearing aid more used by the hearing impaired. The system involves placing an atrium inside the ear. The hearing aid in ear canal are very discreet and easier to accept psychologically. They adapt to the agile people in their gestures seeking a discretion and an esthetics in their hearing aid. However, they have their limit, because they are not made for the hearing impaired with a too narrow auditory canal, too severe deafness or strong cerumen secretions. They need careful maintenance to be functional. Moreover, its handling is often difficult.
Bone conduction devices
This type of hearing aid is specially designed for all hearing impaired people with mixed hearing loss. It also remains the first for people with ear malformations. Thanks to these bone conduction devices, the sound is converted into a vibratory signal propagated by the bones of the skull inside the ear. These conductive hearing glasses have the shape of a pair of glasses and remain very discreet. The prosthesis will be placed in the branches, a vibrator located in the butt on the latter based on the mastoid bone, especially at the rear of the roof, a system allows the transmission of sound.
