Ear clearing or clearing the ears is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure. This need can arise in scuba diving, skydiving, fast descent in an aircraft, fast descent in a mine cage, and being put into pressure in a caisson or similar pressure-bearing structure, or sometimes even simply travelling at fast speeds in an automobile.
People who do intense weight lifting, like squats, may experience sudden conductive hearing loss due to air pressure building up inside the ear. They are advised to engage in an ear clearing method to relieve pressure, or pain if any.

Famous quotes containing the words ear and/or clearing:
“Essential truth, the truth of the intellectualists, the truth with no one thinking it, is like the coat that fits tho no one has ever tried it on, like the music that no ear has listened to. It is less real, not more real, than the verified article; and to attribute a superior degree of glory to it seems little more than a piece of perverse abstraction-worship.”
—William James (1842–1910)
“We should conserve evil just as we should conserve the forests. It is true that by thinning and clearing the forests the earth grew warmer.”
—Friedrich Nietzsche (1844–1900)
