a silly question perhaps

everyone is building this absorber and this resonator etc...and i see them all hanging little bits of string to hold them up.... and im sitting here saying to myself (as i am about to start building my new live room)... what are they to hang the strings on? after pounding together walls wiht countless amounts of money spent on isolating the room...im sure as hell not gonna stick an eye hook into it...am i??? how should i be mounting absorbers and traps to the walls??? idea me!

You connect to the studs in the walls and the ceiling joists up top. You can put hook and eyes into the joists without ruining the isolation. You do NOT want to use anchors in the drywall itself because they will more than likely pull out because of the weight. It's also unlikely you could get an anchor big enough that wouldn't go all the way through your drywall. len

so i'm to anchor to the studs, through two layers of 5'8" inch sheetrock and resilient channeL??

The fact that you used RC would probably have gotten you better answers quicker :? If you're really only STARTING to build your room, you can add extra strips of RC where you KNOW you'll want to hang stuff; map them out so you'll know where they are, then don't put screws into them when hanging your drywall; ONLY use them as an anchor to hang your treatments on. After your drywall is up, caulked, etc, you can run LONGER screws thru the drywall and into these special channels to hang your acoustic treatments. A few screws thru 2 layers of drywall and RC, assuming you've insulated and caulked everywhere, won't be noticeable as a loss of isolation. If this makes you a bit nervous, you can always squirt a dab of acoustic caulk on the ceiling where you've marked the location of the extra RC, BEFORE you fasten up whatever hanger you're using. Another method some have used is to put a layer of MDF under the final layer of drywall, and screw to that; MDF is heavy and expensive though, and this has mainly been done more for walls than ceilings...

hmm alright...
