When a plane takes off, why do we feel pressure in our ears?

The pressure is caused by the speed of the plane at takeoff. You have to understand that going 6o miles an hour in a car does not allow for a pressure change as what happens in a plane . The take off in most planes in near 250 to 300 miles per hour. The plane will lift off the ground as the air going over the wing goes faster than the wind under it. The negative pressure under the wing lifts the plane and this is also what causes the ears to pop, the pressure changes to fast for the body to compensate. if you chew gum it will help ease the pain.

i hope you arent serious latitude??? i hope you mean altitude and your letters just got mixed up... if you are as dumb as the person who asked this question you should be hanged...dont try to get me on grammar its hanged not hung

because you are so high in the air 30,000 feet high so alot of air goes into your ears even if the plane is well pressurized

It is the middle ear that causes discomfort during air travel, and this is so because it is an air pocket inside the head that is vulnerable to changes in air pressure. Normally, each time (or each 2nd or 3rd time) you swallow, your ears make a little click or popping sound. This is the moment that a small bubble of air enters your middle ear, up from the back of your nose. It passes through the Eustachian tube, a membrane-lined tube about the size of a pencil lead which connects the back of the nose with the middle ear. The air in the middle ear is constantly being absorbed by its membranous lining, but it is frequently re-supplied through the Eustachian tube during the process of swallowing. In this manner, air pressure on both sides of the eardrum stays about equal. If, and when, the air pressure is not equal, the ear feels blocked. Air travel is sometimes associated with rapid changes in air pressure. To maintain comfort, the Eustachian tube must function properly, that is, open frequently and widely enough to equalize the changes in pressure. This is especially true when the airplane is coming down for a landing, going from low atmospheric pressure down closer to earth where the air pressure is higher. The act of swallowing activates the muscle that opens the Eustachian tube. You swallow more often when you chew gum or let mints melt in your mouth. These are good practices, especially just before and during descent. Yawning is even better. It is a stronger activator of that muscle. Be sure to avoid sleeping during descent, because you may not be swallowing often enough to keep up with pressure changes. If yawning and swallowing are not effective, the most forceful way to unblock the ears is to do the following: pinch the nostrils shut; take a mouthful of air; using your cheek and throat muscles, force the air into the back of your nose as if you were trying to blow your thumb and fingers off your nostrils. When you hear a loud pop in your ears, you have succeeded. You may have to repeat this several times during descent. This method is called the Valsalva Maneuver and is commonly used by military pilots to equalize middle ear pressure.

There is a difference of air pressure on either side of the ear drum in the eustachian tube, which leads to the middle ear. Because air pressure is vulnerable to changes, the middle ear and eustachian tube cause the ears to feel pressure. The popping sensation is caused when air pressure is equalized in the ears. To avoid this you can try chewing gum, or ice.

Its from going higher than the ground.. Like when you are driving and go up/down a mountain and ur ears either have pressure or pop. I believe its the elavation or something like that.. once you go so high or low, your ears arent used to it and thats what happens. I have heard of people chewing gum and things like that, never tried it, just heard it works.

The same thing happens when you're going up a hill and/or down. I think it could be gravity or the sudden change in climate...oh the elevation that's it. You could also chew gum and they won't pop or the pressure won't be as bad.

because there is a change in altitude, the higher you go up the higher the altitude gets and the more pressure there in your ears.

because when we go u were used to the air pressure where you were which is 14.7 psi and when we go up the air pressure either gets lower or higher (not sure which) so were not used to it so our ears pop
