What is the hearing aid?
The auditory assistance of the bone leadership helps to hear a person by increasing the sound vibrations that travel to the ear drum of man through bones in his head and face. In people with normal hearing, the sound travels to a part of the inner ear that senses the sound of vibrations in the air and also through vibrations in the skull. This type of listener is worn or implanted in the skull, and although these devices are not as effective as hearing aids that intensify the sounds that travel through the air, they can improve hearing in patients who are unable to wear traditional conductivity.
The auditory help uses the principle that travels the sound of bones, as well as air. Generally, bone management is the best for sounds that have a low climb. People with normal hearing perceive the sound of air and bones, although most of the sound is perceived by air.
The most basic form of this type of hearing aid is worn. Electronic components sit by the ear or can be worn on the body. This type of hearing aid is usually atTaking a headband or a specially treated glasses that fit firmly in the head, allowing the auditory help to enter into contact with the skull. The pressure required to connect the hearing aid and the skull can cause these devices to be unpleasant to wear.
Another type of bone handset is physically inserted into the bone. This device is implanted in this part of the skull, which is just behind the ear. Electronic components can be connected to this implant and devices such as TVs or stereo systems can be attached directly to listening through special connectors. These devices are more comfortable to wear than traditional auditory bones, although surgery is required to connect them to the patient.
Hearing aid of bone management is suitable for people who suffer from chronic ear infections or who have a serious hearing loss. MalforMACE or blocking in the ear canal, which can cause hearing loss, can cause the traditional listening to air guidance to be inappropriate. The transmission of Kochle's sound allows you to circumvent the ear canal and improves the patient's hearing with the problems of the ear canal.
