As every diver knows your ears are very important, they can make or break your dive. If you ever wondered what happens inside your ear during a scuba dive you’re in luck we are telling it you!
A video tells more than 1000 words so check out the video out above!
But first what is in you ear?
First you got your outer ear (1) and your inner ear (2). Then you will find your eardrum (3) followed with the Eustachian tube (4).
So what happens with you eardrum?!
As we told you in our other blog, What happens when you hold your breath while you scuba dive, the pressure will build up underwater. So inside your ear the air will be twice as small then on the surface. The eardrum will bend and that is the hurting feeling inside your ear when you dive deeper in a pool or sea.
In the first picture you see a glas and a balloon on top of it on 1 meter. The balloon is your eardrum, when we decent to 9 meter you can see the balloon bend. That is the hurting feeling and when you don’t equalize it’s possible you have a little hole in your eardrum. The balloon is little bit more flexible than your eardrum that’s why we had to do it with a knife.
What is the problem when you have a little hole in your eardrum?
When you go deep enough and you don’t equalize, you will have a little puncture in your eardrum. What results to water in your inner ear and reach your balance organ. The balance organ controls your balance, so when water hits your balance organ your world will be upside down.
What to do to avoid this!
Equalize , equalize , equalize , that is what you have to do! But only when you’re descending. So every 1 meter just equalize through your nose. When you ascend you don’t have to equalize. The pressure will increase and will find its way through your Eustachian tube into your sinuses and out with your normal exhales.
