Apsorption Ideas for multi purpose space.

[impact_kent]

Hey guys..... perhaps someone has some ideas, I have a couple, but they arent fully cured.

I'm running my project studio in a great space in all aspects but acoustic. The space is to be shared with 3 artists that work in the garage and the basement. My live room is to be a gallery every few weeks, and we've done lots of work and put plenty of money into it so far, and I've arrived at absorption time. Leakage is not a problem. Sound quality is my only goal.


After working in many poor acoustic spaces, I have a good feeling about this room, and after some band rehearsals in there, I think that (for some *odd* reason) it has promise. It's a first effort, so I'm not expecting perfection. Far from it I'm sure.

Hopefully I'll have pictures soon (No Camera), but the room is 20' by 20', and there is a 3.5' piece of wall extending from one 20' wall. I tore out the drop ceiling and we had new lighting installed and drywalled the ceiling with 5/8". If I had money for double drywall I'd have done it. Also, the framing for everything, walls, ceiling, is so absurd that I would have gone nuts doing it.

The exterior walls are slat wood siding, cinderblock, and then 1/2" drywall mounted on 2x4 and 1x4 firring strips. There is a 12-15" tall steel "I" beam floating across the ceiling, which slopes from 8.5' to about 9.5'

The floors are newly refinished hardwood. So, with all that said, I thought it was most interesting that while (for the hell of it) playing music in there with all of the ceiling joists and instulation exposed, it sounded pretty damn good in there. As soon as the ceiling drywall went up, it got a bit worse as far as reverb/room sound. Interesting to me anyway..... also, as soon as everything was painted "art gallery white," everything got a little worse. The room, all in all, isn't really so bad however. Not too much room, no noticeable flutters. That's really a nice thing, considering that all my other spaces i've recorded in had AWFUL flutters that would just resonate for seconds. Forget drums.

Anyway, bottom line is that before I attack the control room (which will be 60% its current size after the absorption it will eventually need), I'd like to attack this room.

Putting up rigid fiberglass is the idea, I'm assuming, but I need to create some type of fixture so that it is removable every 2 or 3 weeks for gallery showing, as there will be art and sculptural installations in there.


I'll get some pictures up here later tonight, just found someone to bring over a digi camera.

Wondering what I'll need for a *decent* sound, useable. I dont think I've got the cash to really do a lot. I can probably swing 500 USD. But i do have plenty of wood and tools and such. Hopefully I can spend all of that on the fiberglass panels themselves.

Sorry for the earful, and I'll try and get some pictures up this evening.

Thanks for the forum, it's been my oasis just lurking.

here are some pictures, maybe this will clear a few things up...... I'm just trying to get an idea of what i'll need, how much of it, and then I just have to find a good way to hang material so that I can take it down every now and again.

Just to give you some idea, I just got a delivery of 703 yesterday. 3 boxes, 36 2x4 panels $422.

interesting.......

what kind of coverage is optimal?

I have approximately 1040 sq ft of wall and ceiling space.......

Seems I can afford about 25% coverage...... less considering corners.


hmm

I'm sure the pro's on this site can answer your question but my plan of attack is this. Start with the corners, they will be 4" thick so that will eat up 4 boards per corner. I will then move to the rear wall and treat it, the remainder will be cut up into 1'x1' squares for spot treatment on some of the side walls. The treatment for my mix position is already up and sounding incredible so my main thing is what to do with the tracking end of the room.
Good luck and keep us posted.

Agreed on placement overall; however, if you shop around you may be able to find nearly identical acoustic performance in a rockwool product for about half the cost of OC 703. Might check the Building supplies forum for possible sources... Steve
