By putting in absorbent clouds of various heights you lower the SPL of the reverb (increasing clarity), while increasing complexity and richness, subtle though it is. I tend to doubt that your 15 foot ceiling is far enough away to cause any of these problems, though. If the sound is merely too bright or "hard," conventional absorption and diffussion might do as well (or better?). They look cool, though. https://www.acousticalsurfaces.com/clouds-and-baffles/ 2 1 Quote Link to comment Share on other sites More sharing options...
Schu Posted September 2, 2018 Author Share Posted September 2, 2018 It would seem that it can be a matter of scale... a smaller room would use smaller clouds. I was doing some critical listening last night at some decent spl around 90bd, and it sound like there is quite a bit of reflections going on in the higher frequencies. I order some disbursement plane's, but I think I need some absorption even though absorption is mainly about lower frequency. Quote Link to comment Share on other sites More sharing options...
Shiva Posted September 2, 2018 Share Posted September 2, 2018 Some years ago, I was at a restaurant that had a high unfinished ceiling, polished concrete floors, mostly bare walls and of course the hard surfaces of tables. There was so much sound bouncing around within it, that you could barely hear the person across from you. If the food was not as good as it was, I would have left and never returned. I called over the manager and mentioned that fact and that there are things one can do to diminish all of that sound energy bouncing in the space. He of course knew of the problem. As I only remembered one site, I mentioned RealTraps.com, for something to read up on. The next time I visited, he installed the hanging panels similar to the ones in the first pic. They tamed the room to great effect and it became a comfortable place instead. I was very impressed with the difference. Quote Link to comment Share on other sites More sharing options...
Schu Posted September 4, 2018 Author Share Posted September 4, 2018 I bought a couple disbursement panels to give a try... 32x25x2.5 each. Made of a fibrous paper. Quote Link to comment Share on other sites More sharing options...

Schu Posted September 4, 2018 Author Share Posted September 4, 2018 I am just wondering how to quantify the usage. They only space I have is high on the back wall, but as I listen I think I hear reflection coming from that area... but the spl needs to be close to 90db to really hear that nuance. It may be that I don't listen loud enough for these to work. Quote Link to comment Share on other sites More sharing options...
windashine Posted September 5, 2018 Share Posted September 5, 2018 Any preliminary ceiling install photo's yet, no rush if not, but off work today, and …. you know, just a starting point, the audio wave analysis isn't required, but the unknowns perplex lunch Quote Link to comment Share on other sites More sharing options...
Schu Posted September 5, 2018 Author Share Posted September 5, 2018 This will be a weeekend project... I am going to use to four panels to make two rows of three (roughly 50x96) across the back wall to disburse HF reflections. I am still collating my thoughts on making absorption clouds... but I want to perfect hanging panels for my space. Artistic but effective. 1 Quote Link to comment Share on other sites More sharing options...
windashine Posted September 6, 2018 Share Posted September 6, 2018 The safe way is the best way, especially near the ceiling.... please consider several 5x7 scaffolds. Weekend projects are always successful too, for instance, like if you discover a stud finder would facilitate fewer sheetrock repairs, then it's off to the shop...

Marvel Posted September 6, 2018 Share Posted September 6, 2018 Schu, Where did you get those? I've not seen anything made that way before (not that I've seen a lot... ). Is that like a high grade of molded/formed paper like egg cartons are made? Bruce Quote Link to comment Share on other sites More sharing options...
Schu Posted September 6, 2018 Author Share Posted September 6, 2018 Yes... like egg carton paper. Slightly more integrity but not really thicker. There are many patterns to choose from. There is another one I want to try, but I liked these more organic pattern and wanted to give it first shot. I say each panel is lite enough to hang with four small pin nails, but the permanent solution is supposed to be adhesive. Quote Link to comment Share on other sites More sharing options...

Schu Posted September 8, 2018 Author Share Posted September 8, 2018 Oh... LOL, my bad. Amazon... There are many different patterns and sizes, though each design usually has its own panel size for step and repeat patterning. I am really happy with the quality of the item and initial listening results are positive on the pattern I got... and the color closely matches my wall coloration. I haven't hung the units BEHIND my main LP but I put them on the front wall temporarily and did several back to back listening s and I prefer them in position as opposed to a blank flat wall. 1 Quote Link to comment Share on other sites More sharing options...

Schu Posted September 9, 2018 Author Share Posted September 9, 2018 I hung the front stage... It's certain a large portion of the reflections are coming from the monitor itself, but the little I did here helped. 5 Quote Link to comment Share on other sites More sharing options...
Schu Posted September 9, 2018 Author Share Posted September 9, 2018 I added three panels to the back wall where you would think improvement would be most important... I don't get that warm and fuzzy like I did when I first added the panels to only the front wall. I think it may have taken away some of the liveliness that was magical after the front wall was done. I am going to live with it for the time being as see if I don't adapt. The front wall alone really seemed to clean up the influences of the reflections and got rid of a good portion of the smearing I think I was hearing before.

windashine Posted September 9, 2018 Share Posted September 9, 2018 Seems like a plausible plan for the time being - I mean, this could of gone anywhere, but glad it's inexpensive and blends in. I was about to suggest using the panel's you acquired and glued onto old surfboards, as diy clouds.... 1 Quote Link to comment Share on other sites More sharing options...
