Answer 2

ANSWER

The eardrum serves two important functions in your ear. It senses vibrating sound waves and converts the vibration into nerve impulses that convey the sound to your brain. It also protects the middle ear from bacteria as well as water and foreign objects. Normally, the middle ear is sterile. But when the eardrum is ruptured, bacteria can get into the middle ear and cause an infection known as otitis media.
