    Paolo: I see that your DIY project was about 3 years ago, have you changed anything since? Like, did you flip them around so the fiberglass was facing the wall? Did you leave any spacing between the panels and the wall, and did it make any difference?

    Nop, I left them the way I built them three years ago so I don't know if leaving space between the panels and the walls would have made a very big difference, but I wanted to go for simplicity and lightness of the panels. There was definitely a huge improvement to the sound of the room - my room is 12' x 24' and when I built it it was exactly like yours now - that unpleasant, hollow, resonant space that you get with reflective surfaces like drywall glossy paint and wood floor.

    After mounting the 12 panels I've made, the sound was much better and non-reflective. I could make it even better by building the bass traps that I was talking about in the panel build thread, and that I never got around to making them but the twelve panels are good enough, I think.

    Another thing that helps is a carpet / rug on top of the wood floor!

    The one thing I would differently is the material to cover the OC703 panels: I would choose a better-looking material (even if more expensive) rather than the cheap burlap... it's okay, but it looks... well... like having sack of legumes in your studio There are other materials that cost a bit more but look better.

    At any rate, whichever solution you go with, self-built or store-bought, the bottom line is that you need something to absorb and dampen the bad reflections, and unfortunately foam or egg cartons won't do it - you need mass to trap the sound, which only certain materials like the Owens Corning 703 and similar provide, and heavy drapes / curtains etc and carpet / rugs help too, I've found!

      Don't change a thing. Make a hat out of tin foil, and put it on BEFORE entering the room.....done

        I'd cover one wall completely with sound absorbing material, or perhaps two adjacent walls as already suggested (4" rockwool panels or similar 2-4" away from the wall, e.g. mounted on frames - of course you can cover it with fabric for better looks). Covering two walls might be tricky if you intend to do some serious mixing in there - two sides with differing reflections will seriously impede proper judging of the stereo image. You can perhaps put your desk/monitors in the corner to have surfaces with the same acoustic property on both sides, if two adjacent walls are covered by absorbing material.

        Sound absorption on the ceiling is also something to consider. Bare corners such as the ones facing the 'dead walls' could be treated with basstraps from floor to ceiling (set diagonally and tight in the corner). Maybe I'd use a few egg cartons on remaining bare walls (diffusors would be even better), but I'd not cover them more than about 50% probably less, perhaps 30%.

        If I wanted to invest less, I'd start with basstraps / absorbers diagonally along the edges (walls/ceiling corners first, then wall/wall corners from floor to ceiling). It is important to treat a corner/edge from end to end, otherwise the damping will be much less effective. It worked well for me in a room similar to yours.

          Acoustic treatment and lots of it.

          I had the same issue when I moved to my new studio space. My space is actually rectangular and not the most ideal for monitoring but its what I have to work with. Things that helped me most are the acoustic foam, especially behind the wall mounted monitors which really helped tame frequencies below 200Hz. I also mounted very thick curtains at one end of the room and a thick throw rug (the room has a tiled floor).

          One thing I wanted to mention also is that acoustic foam is expensive and sometimes its just not feasible on a low budget, but you could purchase some polyethylene foam (the same stuff used for yoga matts/gym floors), which is cheaper and could effectively help treat some areas.

            Sound on Sound did a good article on this back in 2006. I like that they explain the "why" very well, and talk about positioning relative to the listener, as well as giving practical solutions.

              Thanks everyone for all your input! I appreciate it! When I get down doing something about it, I'll be sure to post pics as I go.

              I did get a rug to stick on the floor, and it did help a little bit. it's not a very thick rug, I mainly wanted it to keep from making little indented tracks in the wood flooring as I roll around on my hair.
              Hurrr. Derp, derp, derp.

                So... you roll your head around on the floor while recording? What kind of headphones work with that technique? Does it use more headroom?

                  ummmm WTF!! that was supposed to be "chair"! But now I'ma leave that for the lulz.
                  Hurrr. Derp, derp, derp.

                    lol. It looks like a dandy room for musical pursuits, indeed.

                      Indeed so, Mister Plinky. I'm thinking of making a shelvy thing to put on the 2nd tier above the SV and moving the Virus and MPC on it. That'll clear the desk for a controller for dealing with softie synths. I didn't think I'd ever use the Standtastic 3-tier again, but it does let me have all my keys out, even if the XT is only really playable while standing.

                      And now I await my muse.
                      Hurrr. Derp, derp, derp.

                        Yeah, that's the downside of downsitting whilst playing, isn't it? But of course you must DISPLAY ALL THE SYNTHS!!! when you have a nice room like that.

                        No closeting for you.

                          egg trays will make it sound worse

                          acoustic foam will not do a lot

                          just hand four 4'x2' acoustic panel (rockwool or corning) u will hear a HUGE difference

                            DO NOT USE FOAM PANELS.

                            Foam panels sound like plastic and do not absorb sound very good. FWIW. I've been wiring and installing studios for years. One cheap way to build panels is with 1" HVAC duct board. It is 6lb 703 w/ an aluminum backing which is nice so you wont have raw fiberglass on the back of the panels. You should be able to get a 4x8 sheet for $30. Cover it with Guilford of Maine acoustic fabric or an equivalent. Hang the panels with impaling clips. See the link below. You want to install panels on each wall left and right of the speakers and on the back wall. 4x4 or 4x6 would be great. 18" by 8' bass traps would also be great. The goal is to have about 50 to 60 percent coverage.

                              that's true burster

                              seen plenty recording/rehearsal studio, foam all over the room, sound crappy and too dead.

                              703/rockwool , you will hear everything nicely.

                                Then too given the state of digital audio, dry, anechoic sound might be just the thing?
