Equalization On Ascent and Decent

[siwael]

Hello Divers,
I am very new to free diving, Only Scuba with maximum depth 120 feet,

my question is regarding,
During Descent, : I will do equalization with these various techniques available, the air pressure in the middle ear will equalize the required depth level,

but
during Ascent.
the air pressure in the middle ear will increase -with no control how to return back it to the normal level,

in scuba diving while breathing the maximized air pressure is neutralized automatically while breathing, but how about free diving breathholding.


thanks
regards
wael

are u saying u are getting reverse block, or speculating that u will because of the breath hold. scuba is much easier due to heads up descent and slower ascent and descent. If u are getting a reverse block slow ascent a bit wiggle jaw does it for me if I'm sticking a bit.

If I get it right, he isn't talking about reverse block. I guess the question is simply how the ear equalises during ascent.

The answer is really simple, it's actually the same as in scuba diving. The important thing is the pressure difference, so you have two different phases:
1.) Descent: Pressure in the ear is lower than in your mouth/lungs. To change this you need to open your Eustachian tubes and push air into the ear, which as you already said Wael is the normal equalisation, e.g. Valsalva, Frenzel, whatnot
2.) Ascent: Pressure in the ear is higher than in your mouth/lungs. In this case the Eustachian tube opens automatically and the excessive air is moved from your ears to your main respiratory system. So basically there is nothing you need to do. The notable exception is if there is a so called reverse block as written by Josh (monkeyhatfork) in this case mucous blocks the Eustachian tubes so that the automatic release of pressure does not happen. This can, for example, be caused by a cold.

I hope that answers your question.

my question is actually answered by Azrael3000. this is the one i mean,

thanks for your answer, and also Thanks Josh (monkeyhatfork) for his contribution...
