|
|
when i was living in austria, i built myself a screen using cinema screen material with light-proof, fire-proof, sound absorbing, 300g/mē thick, black fabric behind it called "molton". the thing is - "molton" seems to be something german (or at least european), not a general kind of fabric.
now i'm looking for something similar to buy here, ideally already eyed in a curtain-like fashion (fire-proof isn't important but sound absorption is especially important - and the price has to be 20$ max. for each meter at a height of 3 meters) but haven't been able to find anything. i've already tried looking for e.g. stage curtains (that's what molton is often used for) but no luck...
i hope somebody here knows something like that... thanks in advance...

no it doesn't. with that query, almost no online stores appear in the results. the one that i did find, doesn't even carry black molton and is (as i would've expected) located in the UK...

have you looked into blackout material? most fabric stores carry that.

Isn't this Duvetyne?

Yes, Duvetyne is what you want for light absorption. For instance:
http://www.filmtools.com/duvetyne.html
But, a fabric by itself offers little - if any - "sound absorption" qualities. Only at very high frequencies would a simple piece of fabric start absorbing sound at any meaningful levels, and at that point you'd be make the room sound worse, not better. For broadband absorption in meaningful quantities, you'll have to put the fabric over mineral wool or rigid fiberglass board at least 2" thick - and preferably 4" thick for better broadband performance.

well, i wouldn't use the fabric in a professional, usual manner. i just want to reduce outside noise a little and make the inside of the room (or rather the "working area" i plan to create with it inside a room) sound more damp. when i stood behind the screen i had at my old apartment, music playing in the same room was absorbed quite a bit - so i roughly know what results i'd be getting and that's why i want to find similar material...
it seems this duvetyne might be about the same, although it looks thinner... oh well, for now i've gotten enough information to do my own research. thanks a lot, guys
of course, if somebody can think of a fabric that would be even more suitable, please let me know

Duvetyne might do the job for you, but ecrabb is exactly right: a thin fabric of ANY kind can only absorb high-frequency sounds. If you line your room with that, it might sound "dead" because all the high freqs are getting soaked up, but the high midrange & below will be unaffected. That imbalance might be worse than the sound without the absorption. 2-4" of dense fiberglass/rockwool will absorb down to much lower frequencies, giving you a more balanced result.

acoustic quality of the room is actually not an issue because i mostly use headphones anyway.
but i suppose it might be worth looking into whether i couldn't get even more for my money by investing it in fiberglass, rockwool or something else (i found this interesting thread over at the avsforum in the meantime: http://www.avsforum.com/avs-vb/showthread.php?t=1145583 )
