Question

Quizplus · Accepted Answer

The Eustachian tube is responsible for equalizing the pressure in the middle ear with the surrounding environment. During ascension in an airplane or change in altitude, the pressure in the middle ear changes, causing discomfort or pain in the ear. The Eustachian tube opens and equalizes the pressure on both sides of the eardrum, which results in a popping sensation in the ear.
