Bone Conducted Hearing Device
A Bone Conducted Hearing Device (BCHD) is a device that transmits sound to the cochlea by vibrating the mastoid bone, the large bony mass just behind the ear, instead of directing sound through the ear canal onto the ear drum. This device is becoming a more common option for those with conductive hearing loss or single sided deafness. The vibrations of the mastoid bone cause the cochlea to vibrate, so it can “hear” the sound. People with a conductive hearing loss may find a bone conducted hearing device to be an effective way to hear, because it bypasses the middle ear, where the conductive problem exists. There are different options available.
