Your eardrum is a really important part of your ear.
Sound waves travel through the ear canal to reach the eardrum. The eardrum is a thin
flap of skin that is stretched tight like a drum and vibrates when sound hits it.
These vibrations move the tiny bones of the middle ear, which send vibrations to the
inner ear. From the inner ear, the message is sent to the brain, which says, "Hey!
I hear something!" So feel those good vibrations!
