I was just joking (and I thought you were joking about the laser particle counter). Those electrostatic classifiers are for highly specialized research applications.
No I'm totally serious. It should arrive in a couple of days.
I suspect the differences in high frequencies to come from the exact location of objects in the room. Variations from 1 to 5 kHz might come from your own location. According to where you are standing in the room, the sound waves bouncing around your body might cause what we see here (granted that nothing else has moved in the room, open/close door etc.)
Upon reflection, I'm thinking this could very well be correct. While I was exacting in my measurements of the positioning of the speaker and the mic, and I sat in the same location for each measurement on the other side of the room, nonetheless, there were differences in my exact position, and of some of the stuff next to me on the couch.
And while I set the mic up at the listening position, perhaps that's really not ideal, and I'm thinking I should position the mic much closer to the speaker. Then I'll strip the room of all small items, and measure using a delay so I can leave the room.
