Normally, hearing is produced by the sound wave through the external auditory canal to cause tympanic membrane vibration, and then into the cochlea, which is a conventional air conduction.

Another way is to transmit sound through bone, which is called bone conduction. We usually listen to ourselves, mainly by bone conduction. The vibration from vocal cords passes through the bones of teeth, gums, mandible and so on, and enters our inner ear.

For example, when you bite a watch on your teeth, you can block your ears with your hands, but still

You can hear the ticking of your watch clearly. In addition, when we scratch our heads, eat biscuits and brush our teeth, all kinds of sounds are heard through bone conduction.

It is reported that Beethoven, a musician, used a stick to listen to the piano when he was deaf. He opened the top cover of the piano, touched one end of the stick on the piano, and bit the other end in the middle of his teeth. The vibration of the piano string when it sounded was transmitted to the stick, and then transmitted to the inner ear from the tooth bone.

Some deaf people can dance with the beat of music because the sound of music passes through the floor and their bones to the hearing organs.
