After the haircut audio sample, I tried it myself with surprising results. Here's what I did:
I used these microphones and strategically positioned them based on my limited experience: M-AUDIO Pulsar II Matched Pair (small diaphragm studio condenser microphones)
I plugged them into this mixer: Peavey PV8
I recorded using Sony Sound Forge 7.0.
I started recording and then I grabbed a piece of cellophane and started crinkling it constantly as I moved it about while simultaneously stating exactly where it was in the room. Then I played it back, and to my amazement, it really sounded like surround sound.
But I think one of the reasons why this worked is because of how the sound waves bounced around the room depending on where I had the cellophane. I mean, I know this room very, very well, so as I sat there with my eyes closed, I literally felt like the cellophane was crinkling in that exact part of the room and I once caught myself looking to exactly where it was.
So, I think the key is partly due to audio cues with reverb, echo and other Environmental effects. The other cue is visual! That's why the haircut trick works is because they have you close your eyes and then they describe the room and everything else!
So there you have it: that's why it works.
