I would suggest that you pick up a used RTA. (real time analyzer) A Behringer DSP8024 with mic goes for a bit over $225 on Ebay. Its the best investment that I ever made. Using the RTA function, you can see whats going on in your room. Locate the listening position that has the flattest responce. It will show you what that 1/4 turn of the tube trap did. It may take a while to learn how to use it, but it will be time well spent! There are the standard 1st reflection, flutter echo and bass traps in the corners treatments, but how much? You may not need as much treatment as you might expect. When you're done with it, you can sell it.
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
