Thanks, Groovy,
I had not seen that particular Youtube vid. Looks like a nice kit. The reason I was looking into the fractal based diffusion techniques was mainly because I've been "playing with" re-iterated non-integer geometry since the first time I heard of it. With my first computer, finally I have a machine to continue the iterations for me. I am a bit of an artist, "in my dreams."
Problem I have run into is that most of the work I find on this study, that I can access, is either intended for archetects trying to minmize ULF pollution from HVAC systems in giant buildings OR the DOD won't let me read classified documents. Apparently our navy uses this geometry to enhance submarine stealth and they're not sharing. Yet.
Anyway, I have not done more than a couple of months of reading and I find myself trying to re-invent the wheel sometimes. So, no wood lost to experiment, yet. Our January, "ice and snow" move to a new home was off to a great start, but now, a cast from elbow to wrist slows me down quite a bit. Just typing one handed is like trying to seduce a "mean girl with a whip" or something. Let alone setting up my wood shop again.
I appreciate the advice and the links, but you are right about absorption having a massive effect. I moved one of these Ikea mattresses that my daughter bought when she moved out for a while, meant for the "Tiny Home" ilk I think, which is a big foam thing that folds into a table, just behind my speakers in my hard surface listening area and I was amazed at just that amount of absorption in the room.
Already addressed the tile floor with a jute pad and cool rug, but four more surfaces to go. I say four because behind my sweet spot is a wide open "dead sounding" space full of padded furniture with book shelves and my home theater set up. Not much to worry about from that area, except when the "drinking age, living in dad's house" kids are bouncing around in there. ;D
I have goofed some with that QRD calculator that you linked and from what sweep measurements I have taken in my room, I can probably use prime 7 diffusers like you did. I have a massive 6dB+ peak from .8K to 1.3k to deal with early on.
Thanks, again. I have lots to do!
