You don't need to make this room totally dead, covered 100 percent with absorption. It's pretty small, but it's not that small! However, besides bass traps in as many corners as possible, plus reflection absorbers, you should treat most or all the rear wall behind you because that's so close to your head.

I know all about how isolation is achieved, but I'm not knowledgeable about the latest available products. In all honesty, if your main goal is as much isolation as possible, you'll do better asking Rod directly in the Studio Design section at Gearslutz.

Angles won't help, and it's best if you avoid the same dimension for length and height. A small booth like this needs to covered 100 percent with absorption at least 2 to 4 inches thick. According to my Graphical Mode Calculator program, reducing the length from 2,6 to 2,0 with the same 2.6 height and 1.5 width will be pretty good. --Ethan

My own REW tutorial explains how to set the graph ranges to best see the items of interest: Room Measuring PrimerYour question is fairly general, so it will help if you ask one or two specific questions at a time. --Ethan

What type of loudspeaker did you use? And how thick was the desk surface it rested on? It's difficult for me to imagine that much difference! Of course, nobody listens under a desk. --Ethan

I can offer a little advice. Green Glue works well, and the Green Glue web site actually offers a lot of advice about isolation. As far as I know, MLV is not a useful product, mostly because it costs much more than other materials and methods that work just as well.
Do you have Home Recording Studio: Build it Like the Pros by Rod Gervais? It's an excellent resource that includes many detailed drawings.

LOL, so many questions, so little time. Yes, if you bought my book I'm pretty sure all of this is explained. But I'm glad to help even if you don't buy my book. Don't set up facing a corner. The theoretically ideal air gap is equal to the panel thickness. So if an RFZ panel is 1 inch thick, a 1-inch gap is perfect. But you can have an even larger gap and still benefit, especially if the panels are 3-6 inches thick. So a 4-inch panel can be 8-12 inches away and absorb even lower than when 4 inches away. Your room is not square since it has that extra area in the back. --Ethan

That all looks fine, and having a "stepped" rear wall helps the LF response by breaking up those reflections. As usual, the solution is always more bass traps. --Ethan

Everything I know about room modes and ratios is in the article (and help file) that accompanies my mode calculator program: Graphical Mode CalculatorEight different "good" ratios are shown on the program's screen, and I'm pretty sure at last one of them is Sepmeyer's. --Ethan

How big is the room? What treatment do you have now? What can you add?

LOL, agree on all points. This is one of my favorite quotes:

Without knowing the details I can't even guess at a suggestion. But the short answer is there's probably nothing you can do that will help even a little. --Ethan

Yes, you have it correct, and I'll clarify one thing you asked about. You said you have my Audio Expert book, and the relevant section is Power Ratings starting on page 576. Briefly, a device can be damaged by either too much voltage or too much current. If the voltage is too high, the electricity can "spark across" through the air and puncture through insulation or some other part. Too much current flowing through a wire or component causes it to overheat and eventually melt. From that part of my book:
"For a given wire gauge, there’s a maximum amount of current it can pass without overheating. This is the basis for a fuse; many are just a short length of very thin wire."

Don't feel bad, most people can't distinguish subtle differences, and nobody can distinguish some of the audio tests on my web site. It's not that you guessed "wrong" either, as much as you probably didn't go back and forth enough times to realize that the files sound the same. (For many of the tests, not all of them.)

I don't believe that robots have feelings, though they can probably be programmed to respond as if they do. I've been thinking about this a lot lately, about human and animal suffering, and how real it is. We're just a clump of cells! But obviously we feel pain, and loneliness, and joy and depression etc. So I'd rather not have a horrible toothache that lasts for months, as people had to deal with hundreds of years ago. Anyway , I see a clear distinction between audio fidelity versus perception. Fidelity is absolute, and can be defined and measured. Perception is different not only between people, but for the same person only minutes or even seconds apart. --Ethan
