Bone Conduction Type:
It can also be divided into wearing and implantable types.
Bone conduction hearing aids use human bones to transmit vibration signals of sound. The basic principle is similar to the sound people can hear when they rub their teeth, but the bones are slightly deep. In order to get close to the skull, bone conduction hearing AIDS need to be close to the skin, which may lead to local pain and tissue hyperplasia. Therefore, in general, only the hearing impaired with severe conductive deafness, mixed deafness or external middle ear deformity should be given priority.

Implantable bone conduction hearing aid
Through semi-implantation, the external radio device is fixed on the skull through titanium screws and connected through a leather bridge base. The external radio device vibrates the titanium screws and then vibrates the skull, thus improving the hearing impaired person's sound perception ability. In addition to the need for surgery, there are some problems such as implantation failure, damaged parts of the implant can not be repaired, and can not completely avoid skin complications, and the price is relatively high, the advantage is that if properly maintained, can be used for a long time.
