Hi People, I'm getting closer to completing treatment for my home studio, thanks to a bunch of info answering my threads/posts. My room is 11' 6" x 18' and am about to do some measuring, but before I do, I have a rear wall question. The side/back wall corners and the ceiling/back wall corner have 17" x 17" soffits filled with Roxul Safe'n'Sound. (Black) The 3 panels for the face of the rear wall are 6" thick (with the sides cut-out for a little extra effectiveness) and will each have an air gap of 6". (Red) At the moment, distance between each panel is approx. 7". (Pics attached). My question is....Shall I leave the 3 Panels as they appear in the pic, or shall I add 1 more panel, making it 4 panels in total, so as to make it more of a solid wall of coverage? Which will be more effective? Thank You   |

Hey, mrfye. Glad you're moving forward - beautiful work on those panels. "Effective" can have a few different meanings here. In absolute terms, more insulation equals more absorption. Hence, the more panels you put in a room, the deader that room will be. Even so, you need to be cognizant of what your goals require in that context. In other words, you can go on stuffing the room full of broadband or you can take a REW measurement, perform an analysis, and determine where to best place your hard-assembled panels to meet your targets - +-10dB SPL and 20dB/decay within 150ms above 63Hz plus a managed Reflection-Free Zone(s). I've gone over this before here, though I still haven't made a video on it. It's not hard - the information has been on the internet since before I treated my first room - but, if you want maximum "effectiveness" in terms of efficiency then "measuring twice, cutting once" pertains here.
If you don't mind me using your measurements as examples in a future video - no promises, I don't know exactly how to approach it yet - then you can feel free to post your REW with a room diagram, including physical dimensions, and I can try to analyze it for you.

Thanks Hexspa, I think I'll take your advice - leave back wall as in the pic, take some measurements and post them. Hopefully you get a chance to take a look and make some sense of them lol! I don't mind the room being on the deadish side (actually prefer it) ! Just so you can get a better idea of where I'm at...... So far, I've also used same absorption (Black) soffits for the Front corners (floor to ceiling) and Front wall/ceiling corner (pic below). Also, there are 2 panels on each side wall (red ones 48" x 24" x 6" deep) for the RFZ. I will put up a ceiling cloud, but not until I get the measurements done and analized to determine the Final Speaker and Listening position...that's why the room is still a bit of a mess with guide marks on the wall and Side panels not properly hung yet (Sorry about that!) Aaaand, if it all works out, then you can definitely use whatever you need Hexspa, if and when you do a video!  |

Make sure they're in jpg and smaller than 2MB or so.
Deadness is fine but it needs to be in proportion. You can end up with insufficient high frequency energy and even targeted nulls if you put your treatment in wrong. For instance, I thought gapping my cloud 4x was a good idea - nope! Just 1x removed the null that larger gap caused.
It's always worth having a look in REW.

WOW! That's definitely interesting.
I'll take some REW measurements over the w/e and also have a listen to hear what the high-end sounds like and post results.
I also have measurements from before any treatment was put in....what a mess!!

Hah, I'm sure it was. Funny enough, SPL sometimes looks more even before adding absorption; it's the decay that really cleans up. It's like a haircut, you can only see what your head really looks like once the mop is gone - not that I'd know!

I also have measurements from before any treatment was put in....what a mess!! I have same experience as Hexspa. I had two clouds and i moved them up, down, angled front side down, back side up and anything in between. I went full maniac with that. What i found was, they performed best quite close to the ceiling or extremly low (Not really practical that low or aesthetically pleasing.) Thats what i really "Hate" about acoustics, everything affects everything. Your ceiling cloud might perform better at different spot if you add couple bass traps.. Measuring is the key. And you have to be a little(more better) maniac to move something inch up or down and measure. It is really fatiguing... |

Hi Guys, I finally did a whole bunch of Measurements (about 17 million) and need some SERIOUS HELP with them in order to narrow down best Speaker and Listening Position. Instead of continuing here, I created another thread to focus on this....could you please take a look and if you want to use the Results for any reason as examples or anything or to use anywhere....Please feel free to do so. Link to New Thread the-audio-expert.freeforums.net/thread/674/results-analyzing-needed-optimum-postnThank You, Chris |
