When things start moving around your room and falling off of shelves, your room is pressurized. When you can feel pressure on your chest and your pant legs moving, your room is pressurized. Different bass wavelengths (different frequencies) cause different effects to be felt and heard. The tighter the room and the lower the bass that you can reproduce will cause different pressurization effects.
There is another effect that I will call *excitation* for lack of a better word, and that is when you feel like the air molecules in your room are energized. This is more of a high frequency phenomena and maybe the opposite of pressurization. I can give you one good example of a recording that is capable of letting you hear this. There is a country tribute album to the Beatles called “Come Together, America Salutes the Beatles.” It’s mainly a bunch of country and western yahoo artists, but there are a few good cuts. The cut that can excite the air molecules in your room with high frequencies is “We Can Work it Out” by Phil Keaggy & PFR. Nice cover by the way.

There are conditions under which the room is really pressurized. I did try to outline these in my previous post. I stated that it is not a function of bass response only. You can have great bass response , yet no room pressurization... For Room pressurization to occur, the room must be relatively well sealed. Sealing a room is not just closing the doors.. Sound will escape even through the walls ... depending on the room construction ... So the sealing of the room has to extend to the lower frequencies, n always difficult proposition but do-able, nonetheless.
The phenomenon of Room Pressurization is known and not as prevalent as many would think.. Good room sealing at the frequencies where the pressurization occurs is the requisite there ... and the woofer loading ... The vast majority of subwoofers are either sealed, bass reflex or bandpass , few are trly dipoles so they can under the right conditions (sealed rooms, substantial woofer displacement and of course right material) pressurize the room.
I am somewhat beating my head on the subject and will have to drop it but I know that Room Pressurization is less common than people think and it shouldn't be confused with room gain , a completely different phenomenon, or good bass response which is what you are describing here ...
Wish I had the command of someone like Tom Danley or Mark Seaton on the subject.. Guys where are you !!
