Do you mean metal studs? I've only used wood while building this room. They're inexpensive (probably around 3 dollars per stud) but the wall seems to be very solid, save for when I start thumping some music.

I think what I'm going to do for now is cut some 15" ~ bracing to go between the studs, as I have some left over, and the wall that's irritating me is open to the utility room on the other side, maybe shoot a few tubes of liquid nails in all the stud -> drywall mating surfaces.

Hi All,

The industry has been testing and building sound partitions for a while. Check out this gypsum wall board. It is stronger denser and designed to stop sound, including constrained layer and all.

Also check out this page for STC (sound rated) partitions.

STC Ratings

Follow the installation instructions!

Might we be getting carried away with the advice for advanced sound control walls ?

Frankly if it was me, and I didn't mind the couple of hours and cost of material to trash all existing drywall and start over, I'd take Evan's advice and glue/screw a underlayment of 1/2" plywood (not PB or MDF - and use Lo-Root / deck screws for the plywood NOT drywall screws), As he says it'll stiffen that wall up like crazy, and the added bonus of providing sturdy support for any wall hanging cabinets, etc. - and definitely a webbing of construction adhesive for the drywall as well.

Note that you'll need to either remount electrical outlet boxes or use extender sleeves to stay within code for all but LV wiring.

Metal, yes form the diagram. The metal keeps getting thiner (what a surprise there) it's hard now to set a screw down in the drywall (standard gauge is beer can thickness).

I think you are on the right track, glue studs before drywall. If you have a helper you can always get the 5/8" thick board, more work (heavy) but it is stronger.

Good point Chris about the switches/outlets, DD, do you have plastic boxes or metal?

*probably going to need helper anyway.

to clarify my post above - I meant - "strip all gyproc and glue/screw the 1/2" ply directly to studs" - you won't need any more bridge bracing than that!

Hey Chris, I wonder how that wall with the funky hat track compares to a party wall for sound isolation?

well considering the number of layers and careful sealing / isolation of all joints, I'd imagine well enough for most of us not blasting at or beyond THX levels of 105dB

of course if one wanted to get fully carried away:

6moons audio reviews: The Room

page 5 is mostly the details of how this particular system ( IsoDamp) works

take it in context as to the total cost of the room / system - which I gave up trying to estimate - but must be well into the high 6 digits

Good idea for an existing adaptation and if you were starting new you could always begin with a party wall and do it the same way. Thanks for the link.

Hello All,

All the electronics should go on the other side of the party wall in a dedicated environmentally controlled room where all the fan and mechanical noise can be isolated from the party room and all the party animals.

All for Fun
