Sound is conducted through the ear as follows: The outer ear collects and directs sound waves from the environment through the ear canal to the tympanic membrane. The tympanic membrane (ear drum) is a thin membrane that separates the outer ear from the middle ear. Sound waves cause the vibration of the ear drum, which in turn transmits those vibrations to three tiny bones in the middle ear, called the ossicles, which causes the ossicles to vibrate. The stapes, the innermost of the three ossicles, is connected to the oval window.
