Ear planes could be used to reduce discomfort with air pressure

"Discomfort is caused by blockage and/or swelling of a passengers Eustachian tube(s). The air pressure changes induced by the aircraft's descent are too rapid for the blocked Eustachian tubes to adjust properly. However, EarPlanes, provide an equal but opposite impedance on the exterior of the middle ear, allowing relief."
