Two way tube: The eustachian tube equalizes the pressure between the outside world and the inner ear. Air can pass either way in response to outside pressure, whether you are in an airplane, etc. Coughing and sneezing can over fill the tube and swallowing and yawning can open it up for equalization. It is a nifty little system.
