I bought some Owens Corning 703. Now what?

I'm investigating the acoustics of my room. I have been doing REW scans and analyzing them with the help of a member here. I've played with sub and speaker positioning and settings to see how this affects measurement and what it sounds like. I've reached out to GIK Acoustics to get their advice.

But, because I wanted to just try some experiments before (possibly) spending a lot with GIK and/or other companies, I bought 6 OC 703 panels (2" x 24" x 48") to try, temporarily around my room, singly or in combination. I might even make my own panels if that seems worthwhile.

My question is: What are some useful experiments to do with the panels and where in the measurements might I see some changes?

Again, this is not to replace getting expert help; this is a way for me to start to learn by interactive experience how my room is affecting the sound. So, good things to try?

@mitch2  — thanks for those tips. I probably will want to use these for something more than room pads, because like many, I'm not so handy that I will be able to finish these into something long-term good looking.

@tvad  Good suggestion. I hadn't thought of subtracting and then adding back in. That would create a mix of diffusion and absorption I don't have there now.

@riley804 I have read about isolation a lot, but, first, my stuff was on a really solid and low coffee table and then I moved it off to the side. I figured I would sort out the room before the isolation. The speaker stands are new and very solid. Perhaps you'd do isolation first?

@slaw  Thanks for the reference. I'll check into coverings. I really need to see if my 20hz - 300hz range is dialed in before doing too much more with the upper frequencies (using my OC 703); so that's why I call what I'm doing now just "playing."

I’m not sure what the intention of the Corning 703 is for you, but I would spend a lot of time on the Acoustic Fields channel on YouTube.

This might take more effort but if you ceiling is low, it may be tempting to suspend several panels off reflection points on your ceiling.  I would suggest hanging them 4-6" off the ceiling.  Any panel will work more efficiently if you allow space behind it.

I use 2" foam spacers behind my panels

  1. I had swaped places with the stereo and the bed. To get a left and right symmetry.

  3. The method you can use: bass is the most problematic one. And bass is more of a pressure thing. So you have measured your room. You know that you have a peak at for example 73 hz. Take REW signal generator and generate/play back trough your system 73Hz. Take a sound pressure meter (dB meter) and put it everywhere (corners, along walls and so on) and note down what the pressure is.
  4. Take your isolation put it that in those brown/gray sacks that you can breath trough that Santa Claus use. (That goes nice with your bricks, gets a industrial look ;) or as Xmas decoration.
  5. Put the sacks at the positions that you noted had the highest pressure.
  6. You can thank me later :)
