Treating a square room. 9x9 Vocal Booth

[rucontent]

Are there standard acoustic strategies for a square room? One side of the room has windows all across it and looks in control room.

Current mic placement moves around but i here some echo very slight but wonder what i could do to dampen/deaden the room a little more.

Any links to share?
thanks

Only thing i currently have is a bunch 705 rigid fiberglass....

A square room that size needs at least four 2x4 foot bass traps in corners, and a dozen would not be too many. Using 705 is perfect, and the traps should be 4 inches thick. Then you'll need another dozen panels or so, 2 inches thick, around the room on the walls and ceiling.

If budget is not standing in your way I would go with 6" panels for the corners and 4" throughout the room. I am guessing your ceiling is 8 feet high so that is getting close to a cube, which is even worse. Hit the ceiling also.

I totally agree with the above.

Basically, as they both mentioned, a cubical will have double and triple standing waves.. right on top of each other. This can (will) produce huge peaks and/or nulls at different spots in the rooms... sometimes only inches away from each other.

To remedy this you must trap as much as physically possible. The ceiling is a good place to start. Make it as deep as you possibly can - use an air space on top of the traps to increase efficiency and lower costs but put at least 6 inches of 705 on the ceiling.. if you can drop it down 12 inches.. use the top 6 inches as dead air space.

Next, cover every inch of the walls that do not have glass, this includes the door, with absorption as thick as you can manage. We all concur that 4" is preferable. Good luck!

Another question about square rooms which i'll ask here to save another thread... I'm doing my mix room at the moment, its 8x11x9.5 ft (the ceiling being 9.5ft). But at the moment there's a 2 foot deep wardrobe on back wall, removing it would bring the room to 10x11x9.5 which is more space... but its more square. Any thoughts?

I was considering building a large 1D QRD for the back wall in addition to the regular corner bass traps etc... will diffusion be effective/desirable in such a small space?

I would hate to end up mixing in an anechoic chamber. Am I ever going to get a "good" sound in a room of these dimensions?

Kid, I suggest that you remove the doors of that closet. Fill it with light attic insulation. Stretch fabric to contain it.
A serious bass trap at the back of your room. Good start.

Any place for diffusion though? or not practical in a room of my size...

cheers, sorry for the thread bombing

9x9?? I personalty would not put the funds in that direction. Though any open area without absorption could use diffusion.
