Why do our ears pop when airplane cabins change pressure?
Human bodyEar
Quick Answer
Ears pop when the pressure on either side of the eardrum equalizes. The Eustachian tube opens to balance middle-ear pressure with the outside air.
The Full Story
As an aircraft climbs or descends, cabin pressure changes faster than the air trapped in the middle ear can adjust. The Eustachian tube, which connects the middle ear to the back of the nose, briefly opens when we swallow, yawn, or chew. That lets air move in or out and equalizes pressure across the eardrum. The pop is the sound of this pressure balancing.
Key Facts
1.The Eustachian tube links the middle ear to the throat
2.Pressure changes are most noticeable during ascent and descent
3.Swallowing helps the tube open
