Why do our ears pop on airplanes?
Quick Answer
Cabin pressure changes during ascent and descent create a difference between the air pressure inside and outside the eardrum, and the Eustachian tube opens to equalise it with a pop.
The Full Story
The middle ear is a sealed space behind the eardrum, connected to the throat by the Eustachian tube. As an airplane climbs, cabin pressure drops, and the air in the middle ear expands, pushing the eardrum outward. Swallowing, yawning or chewing gum opens the Eustachian tube, letting air escape and the pressure equalise with a popping sensation. During descent, cabin pressure rises and the eardrum is pushed inward; the tube must open again to let air back in. If the tube is blocked by a cold or congestion, pressure cannot equalise and the ear can feel very painful.
