acoustic panel placement

[chadkouse]

My room is 15'x21'x9' and I am building 2'x4' acoustic panels out of 3" OC 701 insulation. I currently have vinyl flooring and sheetrock walls with paint covering.

My question is is there any logical way to determine where these panels should go? How many I need to build?

I am realizing that most people use oc 703 insulation, so I'm hoping 701 will work ok. since it's 3" thick and I'm spacing it about 4.5" off the wall I think it will work ok.

I am also considering building superchunks for 3 of the 4 corners (4'th corner is too close too a door) -- should I buy 703 for that or will 701 work ok?

I'm attaching a few schematics I used when building the rooms.

Thanks

Before considering treatment, I would do some re-designing. Reason is, from your Vertical Section I can see you ears are exactly in the middle of the CR. You NEVER want your head at the halfway point in a room. Here is the reason why. Its the WORST place your ears can be in a CR.

However, don't let the 38% thing confuse you. This is ONLY a starting point. This was a statement by a well known Studio designer, and was only given as a guideline. Over time, it has become a "rule" on the net. It isn't.

Here is your layout in Sketchup and my suggestion.

Thanks for the reply,

Those people diagrams are more for indication of what the room will be used for than anything else. I haven't really even gotten to setting up the control room. I'm still working on live room acoustics.
