bone conduction

The eardrum, contrary to popular belief, is not required for all the sounds we hear.
Some sounds are heard through bone conduction.

What is bone conduction???

Bone conduction is the transmission of vibrations along the bones of the skull or face directly to the cochlea.

You've experiences this if:

• clicked your teeth
• ate crunchy food
• heard a recording of your own voice and thought it sounded odd
