bone conduction

[′bōn kən′dək·shən]
(biophysics)
Transmission of sound vibrations to the internal ear via the bones of the skull.

bone conduction

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.

Bone Conduction in the Pool
In order to swim laps to his favorite music, this man is wearing a Finis waterproof MP3 player that uses bone conduction speakers (one unit is on each side of his head).







Through the Head
Instead of sound waves entering the outer ear (top), the sound vibrates the bones in the head and reaches the inner ear (bottom). (Image courtesy of Cynaps bone conduction products, www.maxvirtual.com)
