Tympanic membrane is the fancy name for eardrum, so when a doctor wants to find out how your eardrum is working, he or she may get a tympanogram. In this test, a doctor uses a special machine that is small enough to be inserted into you ear. It makes a quiet noise that should get your eardrum moving. The result of this test is known as a tympanogram.
