You are right but it is decreasing in volume as your body is compressed.
Equalizing is normally understood to be taking new air in at ambient
pressure to equalize in your ears and lungs etc.


Here's where you're getting confused, Gary: it isn't "taking in" air that's
significant. It's opening the passage between areas with two different
pressures so that air can flow from the high pressure area to the low
pressure area. The high pressure area is your throat. The low pressure area
is your ear. If you open the passage between the two, they will reach equal
pressure.
Explain to me how the air in the throat got pressurized.
