At the moment, I have two bass traps, each about two feet tall. My booth is about seven feet tall. I assume the ideal place to mount them, if I'm going with only those two, is roughly head height, which would be between four and six feet off the ground. But I don't know this to be a certainty. Is there some other way I should be determining where to place them? Thanks.

most bass traps are better placed low and in corners (in front of where your mouth projects). That said, listen closely to your booth, it will tell you what you need and where. Place the traps where you are thinking, recorde a few minutes, and listen.

Move the traps and repeat the above scenario. Do it again until you find the location which best suits your needs and booth.

I was poking about John Sayers' forum ( http://johnlsayers.com ) trying to get some answers for my own booth build and acoustic treatment questions and I vaguely recall someone saying that the tri-corners (i.e., the top corners or bottom corners where three wall/ceiling/floor surfaces intersect) are more critical than the dual corners (where two walls/surfaces intersect). This kinda fits with what Frank is saying, and I have learned that Frank is... well, learned Laugh

Frank speaks rightly. I actually managed it for a while with triangular foam pillows, just to experiment with what would work where before sinking money into more expensive solutions.

LASoundPanels makes a very affordable tri-corner bass trap

If you've got the space for them they provide huge bang for the buck.
You'll get the most out of your 2' tall traps if you place them at microphone level, since they will also act as broad-band absorbers.

Thanks to everybody for the input. Just by way of background, the booth as it currently stands is practically square (37" wide by 41" deep) and 80" high (all interior dimensions) and all the walls are drywall with no acoustic treatment yet applied. The room sounded pretty nice when all the walls consisted of exposed Roxul, but now it sounds like a cave.

In addition to the two bass traps, which are corner traps, I also have four sheets of Auralex-like material that are 20" x 31", four sheets that are 16" by 16", and one sheet that is actual Auralex that is 24" x 28", and I have four furniture blankets. Because the booth is only as wide as the doors, I have, essentially, only the back corners in which to mount the traps. I figured I'd install those first and then arrange the rest of the foam in the remaining available space.

Based upon your responses, it sounds like I'm not off the mark in thinking those traps can be mounted at approximately microphone height (I'll either work standing or sitting on a tall bar stool, depending on how cramped it gets in there) and if it turns out I need even more traps, I can always add them.

Dammit Lee, you already have all your drywall up? Looks like I'm not going to beat you after all. Sure you don't want to take a break, sit back and rest on yer laurels a week or two? Laugh

I started this project over a year ago. I've been resting on my laurels long enough. I need to be finished before Faffcon.
