A bone conductive hearing aid is designed for those who for one reason or another cannot wear the traditional style hearing aid.
How the conventional hearing aid works
The difference between this type and the conventional type is that the conventional type will normally fit into the ear canal and works by delivering sounds through a process known as air conduction. This is achieved by sounds passing through the ear canal to the ear drum which then vibrates, this is what the term air conduction means.
Vibrations are then passed onto three small bones in the middle ear which in turn carries them to the cochlea, fluid that surrounds the cochlea then affects the tiny hair cells that run along the length of the cochlea which generates signals in the auditory nerve. The signals that travel along the nerve go to the brain and the brain interprets them as the sound we hear.
