In which part of the ear does pressure need to be equalized when changing altitude or scuba diving?

The part of the ear that needs to be equalized during diving is called the Middle ear.
The pressure in the outer ear will change with the pressure in the water you are diving through. Between the outer ear and the middle ear is the Tympanic Membrane, or "Eardrum", which will bend, when pressure in the outer ear and the middle ear isn't equal, causing umpleasantness or pain.
This is countered by blowing air into the middle ear by what's called the Eustachian Tubes. By blowing extra air into the middle ear, the pressure inside the middle ear will increase, and since the Eardrum is the only flexible part of the middle ear, the increased pressure inside the middle ear, will cause the Eardrum to bend back to its original position. Hence, equalization...

Is the body saturation faster in altitude diving than at sea level?
No, but there are reduced bottom times compared to sea level diving due to the reduced pressure when you surface. Since ambient pressure is lower at altitude, a comparable nitrogen load will result in easier bubble formation in your body. The major certifying agencies offer courses in altitude diving. Get the course if you are planning to dive at altitude, or read their course books if you are just inquisitive.
What type of pressure is to do with diving?
recreational diving is usually done with 3000 psi of air in a certified SCUBA tank
Why is it important not to hold your breath when diving?
As you ascend from diving the surrounding water pressure decreases. This means if you hold your breath and ascend the pressure on your body decreases so your lungs start to inflate until........pop
How does depth affect pressure?
More depth equals more pressure, thus why ears pop when diving in water.
Why when going deep sea diving you should not go flying?
There are definitely some well stated guidelines for flying after diving. Here is some information.The concerns of heading to altitude too soon after diving are the same as those when you ascend from your dive too quickly because the same scientific principles apply: Going to altitude takes you to an area of lower outside pressure, meaning residual nitrogen still dissolved in your blood can come out of solution as bubbles if the ascent isn't slow enough to let your body off-gas. This is why it's so important to ensure you've off-gassed any nitrogen in your system before going to altitude. The more diving you do, the more residual nitrogen you'll amass, so the amount of time you should wait relates directly to the type of diving and how many dives you make in a given period of time.I recommend waiting at least 24 hours before flying after diving - better safe than sorry - but if that's not possible, the following shows the minimum guidelines for different diving circumstances, based on flying in commercial aircraft.A single dive within recreational limits: 12 hoursMultiple days/multiple recreational dives: 18 hoursDecompression diving (planned or unplanned): 24 to 48 hours
What is the best definition for a squeeze when its related to diving?
Effects of Increasing Pressure when diving which results in pain or discomfort in your body's air spaces. A squeeze is best defined as a condition that causes pain and discomfort when the pressure INSIDE an air space of your body is LESS than the pressure OUTSIDE an airspace.
Why are drivers watches pressurised?
So when diving the water pressure cant force its way in
How is science used in diving?
To know what the pressure is, indicate how you will have to submerge and go up, how to swim...... Everything.
What natural elements must a scuba diver overcome when diving?
they must come over the pressure
Why must diving suits be rigid instead of flexible?
The rigid diving suit is pressurized to offset depth pressure and it needs rigidity to prevent it from expanding, allowing the person to swim easily.
What is the difference between persuit diving and deep plunging?
Pursuit diving exerts greater pressure on the seabirds while deep plunging refers to going deep in the sea in search of the seabirds.
How blood pressure is greater than atmospheric pressure?
Blood pressure is the blood flow when the heart is pumping (top number) and when the heart is resting (bottom number). The body is a closed system and requires enough blood pressure to pump the blood throughout the body. A typically healthy blood pressure would be 120mmHg/70mmHg. Atmospheric pressure is the weight of the atmosphere at a specific location and altitude. At sea level, atmospheric pressure is 760mmHg. So actually, atmospheric pressure is much greater than blood pressure. Most people never have to worry about atmospheric pressure affecting blood pressure. However, deep sea divers experience an increase in blood pressure while diving, and astronauts experience a decrease in blood pressure when in space.
