In both cases, flying on an airplane and diving there is pressure in his ear. Can anyone find a table of size compared to the depth and amount of pressure in your body? For example. From 30 feet deep is equivalent to 10,000 feet high, and both have 2 times the pressure? This is just an example and not have the data behind it. That's what I'm looking for. I had problems both ends so that the pressure in the middle ear and want to know what is equivalent in both? Thank you.

Pressure drops with increasing altitude.
