I just remembered something related to what's discussed in this article. Back in the 90's someone discovered that taking a box of Dixie stir sticks and aiming the holes toward one of your ears would create really bizarre effects in your head.
First of course is the "eardrum suck" but there are also some other interesting illusory effects. I actually managed to find that very page about it: http://amasci.com/freenrg/audhole.html
People often feel disoriented and "stuffy" when they enter a sound proof room, like a recording studio or hearing test booth, or in a stadium, calm snow fall, etc where you don't hear echo / reverb of your own voice and other things around you. It's the same illusion again. Your brain really wants to experience the room ambiance, and gets funky when that information is missing.
