The eardrum (tympanic membrane) is a thin, oval layer of tissue deep in the ear canal. It helps protect the delicate middle and inner ear from the outside. It is called an eardrum because it looks and acts like a drum.The eardrum receives vibrations from the outer ear and transmits them to the small hearing bones (ossicles), of the middle ear. Because it is so thin, the eardrum can be ruptured or punctured. The hole exposes the middle and inner ear to damage or infection.t helps protect the delicate middle and inner ear from the outside.

Once the sound waves travel into the ear canal, they vibrate the tympanic membrane, commonly called the eardrum. The eardrum is a thin, cone-shaped piece of skin, about 10 millimeters (0.4 inches) wide. It is positioned between the ear canal and the middle ear. The middle ear is connected to the throat via the eustachian tube. Since air from the atmosphere flows in from your outer ear as well as your mouth, the air pressure on both sides of the eardrum remains equal. The eardrum is rigid, and very sensitive.
