A Tympanometry test detects problems such as fluid/wax buildup, perforated eardrum, ossicle bone damage, or tumors in the middle ear. A physician would use a tympanometer to conduct this test.
During a tympanometry test, a tympanometer with a soft plug is placed in your ear. The plug will change pressure, make a loud noise, and track your responses to the sound and various pressures. Movement of the eardrum is measured as well as the reflexes of the tiny muscles attached to the ossicles.
