You don’t avoid resonances by putting walls and ceiling out of parallel with each other. Its purpose is to help avoid first reflections and flutter echos.What you want to do is use shims at strategic points to knock the walls and ceiling out of a parallel surface situation to avoid resonances.
How do you move resonances to non-musical note frequencies? Non-parallel walls shift modal resonance frequencies only a few Hz provided volume is about the same.Move the resonances to non-musical note frequencies.

Non-parallel room surfaces make resonances more unpredictable, not avoidable.

This.Truly down the road of soundproofing you need walls within walls nothing touching so to speak... .touching = transfer vibrations..
This.
I built a sound proof room in the basement of my new house.
I was lucky to find a local guy (Sonic Space) who designs rooms like this.
The only real magic in his design was the separation of the jam room walls, from the house structure.
It's not hard to do, but it makes a HUGE difference.
A couple other tips/tricks:
- Surface mount electrical (so only small holes in the wall for cable to come through)
- Heavy dense doors (mine were custom made by a buddy of mine)
- 'Zero Seals' around the door frames (like the trim around a walk in fridge)
- Create as few of holes as possible in the walls (I have a surface mount AC/Heat unit and two grates for air in/air out - and a fan on the outside of the room to create constant airflow)
Full hard rock band playing in the basement, wife and baby one floor above (and a few rooms over) watching TV peacefully.
It wasn't cheap, but it was money well spent.
Do you know the math, or could you point me to a source? I'm not arguing that good sounding rooms aren't possible BTW.If you know the math, it is possible. That is why people like Alan Sides were paid large amounts of dollars to engineer good sounding rooms.
Not through the means of non-parallel walls, and somehow shifting resonant frequencies of a room in any significant measure. That was the point I was making.I have been lucky to physically visit a few of the rooms. If you have experienced them, then you would know it is possible to make a room that does not resonate on certain audible notes.
Anechoic chambers do not eliminate all reflections, and they certainly do not eliminate modes.On the other end of the spectrum, one can create an anechoic chamber if the idea is to eliminate all reflections & modes, but that environment sounds really dead and unnatural.
That’s a nice room! And a man won’t worry about other men’s opinions. Lol. Build it how you like it. The sign above my door: View attachment 46996
My space in the house.
For me, floor contact was not an issue since it's a basement. I have carpet over the concrete.How does one isolate the floor contact ? We used to put our speakers onto tennis balls back in the 80s but a whole room ?
I was walking through the river venders alongside the water in Savannah, Georgia and met a man there who made whatever sort of signs you wanted. I don't recall his name, but you might be able to search the net for him.Wow that is a nice sign!
Where did you get it?
No AC up there but a portable can be had for cheap

Again, I don't have anything to say against your first source, or that one can work around room resonances.Check the link in my first source.
If that is not intensive enough, there are more complex formulas you can find with a search.
If your main goal is acoustic isolation and avoidance of room resonances that are actual notes, and excessive reflections, it's possible to get 95% there. I have worked in several rooms like that.
+1 on the Roland EKitThis is what I read. I doubt I could ever 100% sound proof it, being built on top of the existing garage. I can do a lot to limit the noise. I think I could actually get it framed with aluminum inside the wall space to provide an air gap, plus the aluminum framing is cheap. But I'd also need a floor that's separated from the plywood floor that's installed.
I'll probably do what I can and feel out what the neighbors can tolerate. I've got an AX8, so I don't need to crank it to get the tone and my buddy has a Roland elec kit.
