Air pressure is lower at high altitudes. An airplane cabin can adjust, but as the plane rises, passengers can experience temporary pain in their ears. Check all facts below that explain why.
The air pressure in the ears increases.
The air pressure in the ears decreases.
The volume of air in the ears increases.
The volume of air in the ears decreases.
The change in volume causes discomfort.
It takes time for the ears to dispell excess air past the ear drum.

Check the ones that explain ear pain during ascent:
- The air pressure in the ears increases. — YES (with clarification). When the plane rises the cabin/ambient pressure falls. If the middle-ear pressure doesn't fall as quickly (Eustachian tube closed), the middle ear pressure is higher than the outside pressure, so the pressure across the eardrum is effectively increased.
- The air pressure in the ears decreases. — NO. Ambient pressure decreases, but the painful situation is that the middle ear pressure stays relatively higher, not that the ear pressure falls faster than the cabin.
- The volume of air in the ears increases. — YES. Trapped air in the middle-ear cavity expands as external pressure drops (Boyle’s law), which can push the eardrum outward.
- The volume of air in the ears decreases. — NO. That happens on descent (external pressure rises), not on ascent.
- The change in volume causes discomfort. — YES. The pressure difference and resulting stretch/bulging of the eardrum and surrounding tissues causes pain or a blocked feeling.
- It takes time for the ears to dispell excess air past the ear drum. — NO as written. Air isn’t expelled “past” the eardrum; equalization happens through the Eustachian tube to the throat/nose, and that opening can be slow or intermittent — that delay is what causes the pressure difference and pain.
Quick remedy: yawning, swallowing or gently performing the Valsalva/Toynbee maneuvers helps open the Eustachian tube and equalize pressure.
