A hearing aid that works by gently vibrating the skull to produce hearing, rather than by putting sound in the ear. Bone conduction hearing aids are used for large conductive hearing losses that cannot be medically corrected.
Bone Conduction
The transmission of sound (mechanical vibrations) through the bones of the skull to the inner ear. This is largely how we hear our own voices.
Bone Anchored Hearing Aid (BAHA)
A special kind of bone conduction hearing aid. A titanium “post” is surgically implanted into the mastoid bone behind your ear. Once this “post” heals and the bone firmly grows around it (about a month), the hearing aid itself is snapped to the post. The hearing aid vibrates the post, which in turn vibrates your […]
Body Aid
The largest and most powerful of the conventional hearing aids. The body of this hearing aid is about the size of a pack of cigarettes and can be worn on the belt or in a pocket. Sound is carried from the aid through a small wire that leads to an earpiece.
BOA
See Behavioral Observation Audiometry.
Binaural Summation
Sound received from two ears is perceived as louder than sound received from just one ear.
