The tympanometer measures the admittance or compliance of the tympanic membrane while different pressures are being applied to the external ear canal. The compliance of the TM is measured in cubic centimeters, and the pressure in the ear canal is measured in decapascals (daPa).The probe has different size plugs that provide a seal at the entrance to the external ear canal.hysics of the Tympanogram.
