The tympanogram is a test that measures how easily the eardrum vibrates back and forth and and what pressure the vibration is the easiest. The middle ear is normally filled with air at a pressure equal to the surrounding atmosphere. If the middle ear is filled with fluid, the eardrum will not vibrate properly and the tympanogram will be flat. If the middle ear is filled with air but at a higher or lower pressure than the surrounding atmosphere, the tympanogram will be shifted in its position.
The tympanogram is a quick and easy test. A special probe is placed up against the ear canal, like an ear plug, and the equipment automatically makes the measurements.
