Well, the contractor put the carpet up in my studio closet (walls and ceiling, area rug on floor). It looks cool and absorbs great high pitched sounds, but I still have a heck of a bass trap in the corner of the wedge. I was thinking about storing my leftover vinyl flooring roll back in this corner, perhaps that will help. Does anyone have any good bass sound absorption material they could mention? The space is quiet and has a nice hush to it when youre not miking acoustic hand drums... which was my intent for the space... any help is very appreciated. The room is roughly shaped like a wedge of cheese, flipped onto its side: slanted ceiling.

Jan 10, 2013 08:38 pm What if I nailed some cushioning material like upholstery cushions or cloth/polyfill seat covers to the slanted ceiling?
Or would one of those floating cloud sound absorbers be a better investment?
Its 6 1/2 x 8 feet on the floor. About 8 feet high at highest point, and two feet high by the floor.

Jan 11, 2013 02:15 pm Not sure if this is the ideal solution, but something I did in my studio just to do something with all my leftover materials.
Get some rockwool or whatever pink insulation and wrap it in a giant piece of felt (from fabric store) to form a 6 ft giant stuffed burrito. Use glue or staples to seal the felt ends together. Then, just lean it against the corner (or pin it to the wall somehow). I have mine hanging from ceiling hooks.

Jan 12, 2013 09:20 am Fiberfon microslab is supposed to be a rockwool designed for sound absorption. I've read also that its better to use slabs vs rolls of the material, as the slabs are denser.
I love it when a plan comes together... I think im going to fabricate some acoustic panels before too long. :)

Jan 13, 2013 10:21 am Yeah man.... bass traps are the way to go if you got the room. Was thinking you were just looking to fill a corner. I did something similiar with that design in my room. Check out my pics:

Jan 14, 2013 09:35 am Thanks for sharing, Hippie! How are those rockwool panels working out for you? Would you say that they make a noticeable difference in absorbing noise from those drums? Yup, thats just the kind of treatment I was thinking of.

Jan 14, 2013 10:12 am Like night and day..... my recording room is where I have band practice too. The cut in noise bouncing off concrete walls was dramatic to say the least. The rest of the band members were impressed at how much cleaner practice sounded.
It's kinda funny.... because you can actually walk into the room and already get that sensation of 'echo-less-ness' like you do when slapping on a set of fully enclosed headphones. My room is not perfect, but for the whopping $200 it cost for materials, I'd say it was definitely worth it.

Jan 16, 2013 02:30 pm Ive been reading a lot about "acoustic cotton" treatments. The irritation associated with rockwool is something that I might choose to avoid altogether. Theres this material called UltraTouch insulation that looks really promising. Its 80% post-consumer recycled cotton denim fibers. Cotton has great sound absorbing properties, with an increased absorption of bass noise. Sounds perfect for my boomy little space. I may fill up some pillowcases with that junk, sew them shut, and throw them into the corner to soak up bass. www.acousticalsurfaces.co.../ultratouch.htm
That is the "loose fill" stuff. Also thinking of getting some 2" cotton "slabs" to hang on the walls... www.bondedlogic.com/const...oustical-panels
I started talking about rockwool panels to my wife, and she had some health concerns about this manufactured material. I started talking about using reclaimed cotton as healthier and greener alternative, and received real support for the idea. I personally would rather use cotton as the greener material choice anyhow, so I think im committed.

Jan 25, 2013 09:24 pm I stopped by the Home Depot tonight to look for green insulation materials for a good (and cheap) bass trap for the corner of the big triangle. I found that they had this stuff called GreenFiber (www.greenfiber.com) for around $6.50 for a big 18 pound block of the stuff, which seems a little more cost efficient than the UltraTouch material. The GreenFiber manufacturer rates it at an NRC of .9 so I figured i'd check it out, for that price. I walked out with 4 blocks of the stuff. Ok, I guess I have my pillowcase stuffing!
I wonder if I can lightly "saw" through that stuff to make filler for panels? It is packed into cubes already... Or would it just disintegrate? I may soon find out.
