Bone Anchored Hearing Aid Device, BAHA
A bone anchored hearing device (BAHA) is a surgically implanted piece of equipment designed to restore hearing for people who otherwise have a hearing loss. A BAHA is most likely to benefit someone for whom hearing aides are not effective but who have functioning in at least one inner ear. Sound waves are transmitted through the BAHA and into the bone in which it is implanted; the bone then sends the vibration directly to the inner ear. Not to be confused with a cochlear implant, which sends electrical signals, a BAHA sends vibrations to a working cochlea.
