Reduce boominess..is that a word?

So, I posted in the construction section that I finished my studio. I also posted this same thing on another forum, not word for word though. My room is 17'x13', but 10' down, on the right front of the room, the wall goes out 2' more for the last 7', sorta like a tetris piece, the upside down piece. I will also post a crappy diagram below. Since the room is all hard surfaces (double 5/8 on the ceiling, a mix of 5/8 where concrete is on the other side of the frame, with a 2" gap and double 5/8 where concrete is not existing, as well as some laminate flooring), it sounds very boomy. I cannot think of another way to describe it. I played my snare drum in there and it just is loud and boomy. The sound is not clear. From what I read, which could be completely misunderstood, I need bass absorbers. I plan on using the design by StudioDrums, with the 703 or rockwool, with a back mounting wood frame, covered in burlap, but 4" panels rather then 2". The front of the trap will not have wood, nor the sides, just the back. My two questions are these- 1) will the addition of bass traps cut down on the boominess I am experiencing, thus cutting down volume in the room, and possible slight leakage to the floor above? 2) do I have enough traps? I know I can always add more, but is this a good start? Thanks!

anyone? Do I need to provide more info??

Hai there TJ, 4' panels are good. Remember; thicker panel is better low-frq absorbing. There's plenty of corners in a room, wall/ceiling & wall/wall & wall/floor. The first 2 are eazy to fill with basstraps. The wall panels will act more as broadband. You might wanna put a small plastic layer on the front (under the cloth) of the BASS traps so you won't absorb too many mid/high frq with that setup. Consider ceiling panels as well if you've got a hard floor. Boominess is a word, or atleast in the world of acoustics :) And yes, by adding BASS traps (the thick panels of wool) you WILL lower that phenomenon. But soundleakage to adjacent rooms will still continue. Tho, when there's less boom there should be less low frq leakage... You can't have too many BASS trap, but you CAN have too many midrange absorption. Be ware of that. You need LOW frq absorption at first. now :shot:

Thanks Ro- I figure if it is a little quieter in there, less will leak. My reasoning, which might be off, is that SOME of the leakage is the reverb in the room. Not all of it, but some of it. Thanks again!
