bone conduction definition by American Heritage Dictionary
bone conduction - Computer Definition
Transmitting sound via the bones in the skull to the inner ear. Bone conduction speakers rest against the side of the head near the ears, but not in them. Dating back to the 1920s, bone conduction has been used for hearing aids and is still used for people who cannot tolerate a device inserted in their ears. Why You Think You Sound Different When you speak, you hear your voice from your ears as well as the bone conduction in your head, which is lower pitched. When you hear your recorded voice, there is no bone conduction, and you sound higher pitched. See Bluetooth headset and Google Glass.
