Bone-conduction hearing aid, head-worn

Definition

An electrically-powered, external, acoustic device intended to compensate for impaired hearing by transmitting vibrations, from transduced sound waves, through the skull to the inner ear. It typically incorporates a microphone, amplifier, and vibrator mounted or magnetically connected to a head-worn device (e.g., headband or spectacles); it may include positioning and protection devices. The microphone receives sound waves and converts them into electrical signals sent to the vibrator which transmits vibrations, typically through the mastoid bone, to the inner ears for hearing. This device is typically used to treat hearing impairment due to middle and/or outer ear obstructive pathologies.
