The tip of the probe has a pressure transducer that changes the pressure in the external ear canal from negative, through atmospheric pressure, to positive pressure. While the pressure is changing, a sound transmitter sends a sound wave to the tympanic membrane.hysics of the Tympanogram. If the middle ear space is filled with fluid, most of the sound is reflected back to the probe from the stiff tympanic membrane.
