Like you guys suggest, I’ve also found it a good training exercise. It involves creating a slight negative pressure in the ear (internally) to simulate preferably a dive, but what you might feel in an aeroplane from time to time. It is intended to be very gentle without the complications of using submersion to experiment, and is merely an attempt to stimulate the muscles involved so you can feel them.
I’ll try and explain how I simulate it. It is the same as suggested really but sometimes different descriptions hit the mark for different people.
If you can equalise ‘pinching’ then this is just the reverse in principle to start with;
Instead of creating positive pressure in your mouth throat, by whatever means you use, ‘pinch’ and VERY GENTLY draw the tongue down or pretend you are sucking on a very thick milkshake. This should cause a slight negative pressure in the ears. I find it is indicated by sound getting very fuzzy, almost like that confusing sound effect swimming pools seem to create, with high pitch noises becoming more significant (my computer fan suddenly becomes much noiseier whilst other sounds are deadened).
