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?

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 :)

Ditto on the "edunbar" post... If your serious about learning; treating; and
getting the BEST acoustic results in your room...acousticfields.com.(Dennis Foley). This is the 'WAKE-UP CALL'...You will soon realize nothing else comes close !

@hilde45      looking at the drawing of your room, have you thought about making some changes? have or can you put the stereo where the bed is and then you could put the couch where the door of the bed is and the bed could go where the couch or stereo was?      with the stereo where the bed is, you would have side walls and if you had panels left over could put them on stands and have them behind the couch.

just a thought......

@edunbar and @tazz2 Thanks -- I will go take a look. I've watched a lot of videos about acoustics and treatments but perhaps there will be something additional here to learn.

@corelli I'll consider suspending the panels. Once a 2" panel is suspended down 4" from a 6'5" ceiling, it is now at about 5' 11 inches from the ground and just about low enough for someone to bump with their head. But I think that this is at least a temporary experiment that will bear fruit. And maybe even an 1" off the ceiling would be good.

@slaw 2 inch spacers sounds like the easier way to get corelli's suggestion implemented. Thanks.

@optimize Thanks for the suggestion. I've played test tones and walked around the room your suggestion about the panels in a sack is interesting. I'll try that. I'll just thank you now, if that's ok.

@riley804 I have not tried the stereo where the bed is (in this room, it's impossible) but I have tried putting the stereo at the opposite end of the room, in other words, on the short wall. It is not as good. Still, I have not tried it with treatments. That's a good experiment.
