You may hear a squeak or popping sound as the air pressure equalizes. Fluid in the Ear The most common cause of fluid in the ear is an infection, but it can also be caused by other medical conditions.
Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization 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.
There is no air bubble between the tongue and the roof of the mouth to compress. Keep in mind that after the tongue contacts the roof of the mouth, you won't be able to equalize (since there's nothing to compress) until you transfer a bubble of air between the two. Allow a pocket of air to enter from the lungs to the mouth by breaking the ...
If this fails, then the Valsalva maneuver may be used. This maneuver, when used as a tool to equalize middle ear pressure, carries with it the risk of auditory damage from over-pressurization of the middle ear. [1] [6] [8] The Valsalva maneuver generates about 20–40 mm of Hg pressure. [9]

On ascent, the air in the paranasal sinuses will expand according to Boyle's law, contracting during descent. Normally, the sinuses drain into the nasal cavity through small ostia , which permit mucociliary clearance and ventilation that equilibrates pressure.
