Rehearsal basement, changing accoustics

Hello I'm planning to improve the accoustic in my rehearsal room (not a studio, a room with recording possibility). For now we have walls covered with curtains (not too thick, but waved) and egg boxes (paper). The ceiling is also covered with egg boxes. I dont want to make it full professional, i would rather do it on the lowest costs possible. So i think about creating panels from mineral wool sticked into wood frames (something like this: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=4581, but probably with normal thick mineral wool (it's cheaper). So i have planned how to set few pannels in my room: (see the attachment 1) and SketchUp file: http://www.megaserwer.neostrada.pl/rehearsal.skp In the corners the panel will be the same as others, but maybe we would set the bass traps there (but for now we dont know how to do it as simple as those panels). The sizes of these panels are (WxH): - 0.5m x 2.0m for corners (in one corner it will be shorter because of vent) - 1.0m x 2.0m for wall near table with pc and monitors - 1.0m x 1.5m for wall opossite above (because outlets, and vent) - 3.0m x 1.0m behind drums The spaces beetwen the panels will be filled with curtains, and on the ceiling we could leave egg boxes (for now). In point (A) we will put big shelf, and maybe we put some panels in point (B) as this is the space where monitors are near. I dont want totally deaden the sound of drums so i leave the point (C) without the panels (only curtains). So, every help would be appreciated. Cheers Ps. Height is 2,07m. Ps2. If you would like i can provide UK units instead of meters.

Let me the first one to say, please remove them egg-thingy pannels. They're not fire proof and will do NOTHING to accousics. Why not add a drumriser while yer bussy. It'll improve the overall sound in the room to much beter detail (less boomy bassdrums etc) Search this forum and follow the stickies for more on the pannels. Remember to absorp in all frequenties to deaden sound (what I mean is that if ye only use some simple panels you'll end up dampeninng mid/high frequencies and leaves you with lotsa bass in the room)
Alright, i did some researches and found that i could do it with Rockwool rw3 or rwa45 (Rockwool because i have easier access to this stuff). First I will do those panels in the corners. As this should handle the low freqs is rw3 or rwa45 suitable? Or should I get something thicker? And i've got another question. Do size of panels matters? Wil it be better if I build two smaller instead of one big? And should they cover whole height of the wall, or can be smaller?
just one q! why don't you sit where you depicted your drumkit, facing the "window"? better symmetry, adn then just move around the drumkit until you find a good spot where it sounds good (for the drummer and in the mic's)? a

Yeah, good point. That is because we set the instruments first (this is our rehearsal room, first) then set the recording equipment (just without thinking, in the empty place :oops: ) We should try this...this would simplify a few things :D
it shure would! :lol: symmetry will change the situation to something a lot easier to calculate.. that's why..it does NOT make it sound "better". If you like sitting on the side just hearing the drumkit on your right ear the reflexes from the wall on your left AND your used to it, then go ahead, but if you put thing in symmetry it would help a lot to make sure you get thing right every time you do it. .. Me personally never set up symmetrical, ONLY in a separate control room listening situation. a
What you might consider (since recording is secondary to rehersal), is making your "mixing station" on wheels. If you think about it, when you are recording, you don't have to listen to the sound you are recording (except maybe on headphones). Once you've recorded the song, roll the desk into a good position for listening/mixing and mix there. Besides, if you've got the drum kit playing live, you're not going to hear anything from the speakers while you're recording anyway! If you can hear the recorded drums, you're probably also going to be feeding the speaker output back into the drum mics. Playing/recording and mixing are two different activities that should take place at different times and under different conditions (unless you are mixing a live concert for an audience of course). If your space (and budget) is limited, spend a little for some wheels (and bungee cords to tie everything down with!) and then do one thing at a time. I don't think you're going to be able to go from mic to CD in one shot so why try? len
