Acoustic TReatments - What, How much, & Where?


Hello all you room treatmentfiles.

Being at the point where I probably should have begun, now, I want to 'treat' the room, acoustically. Economic reasons say I might have to go by way of ‘foam’ stick ups on the wall, but I’d really rather not. The desired alternative, however, is panels, and they are mighty pricey. OK.

Reading over the online info at various panel makers websites, (ASC, RPG, GIK, etc), some panels have different ranges of absorbtion, reflection, etc. according to the makers.

Q: How do you know just the amount of absorbtion, or diffusion to incorporate into the room via panels, traps, etc.?

Is there some Rosetta stone that will decrypt this for me… or is it all “trial & ear-ror”?

GIK panels seem the most feasible cost alternative, presently.

Any suggestions or related experiences in regard to sources for, or treatments of, will be more than a welcome thing.

Thank you
blindjim

BJ,
I wouldn't go with the auralex foam either, but the drawing you'll get from auralex will give you an idea of room treatment placement. From that point you can address the areas any way that suits you. I'll be building my room treatments this winter...looks like a no brainer. I'll be going with the super chunk approach with rockwool or owens corning 703 or 705. Some panels also.

Wander around the acoustics forum as they have some good designs that are easy to make.

Search "studiotips and "superchunk" on google & you'll pick up some useful hits.

This link is a mother load of info on the topic:

Also you might go to the auralex site and send in a request for a room treatment design (it's free). You can get an idea how they'd treat your room...it'll be pretty much what one would expect after you read everything you've mentioned(ethan's white paper) & my links here. You'll treat the corners (all 4) for bass, then the first reflection points on the walls & ceiling...etc..
