Dental Hearing Aid

Dental Hearing aid that transmits sound via your teeth has just been approved in Europe. This Device, called SoundBite, is primarily designed for people who are deaf in one ear. It attaches to the upper molars (left or right) and once in place is barely visible. However, the typical hearing-aid look isn't completely tossed aside; the device on your teeth "communicates" with a small microphone in your ear. The small ear mic picks up sound from your surroundings and transmits them wirelessly back to the device in your mouth, providing the ability to hear spatially.


Typical hearing aids use air conduction, a method that employs the middle and outer ear to increase sound volume. The dental hearing aid uses bone conduction, an entirely different approach that directs sound vibrations from the bones in the skull to the inner ear. Bone conduction is believed to effectively simulate the natural hearing experience that takes place in the ear.
