Starting my build tomorrow. It's a 30x11x8.5 room, with foundation walls on three sides. The fourth side is the kids play room. I'm not worried about sound traveling to that room. Due to budget I'm limited to what I can do sound isolation wise. Going to do DD but no GG since that would add to much in cost. Will add GG acoustic sealer to all edges and was thinking of GG on studs only or the joist/stud gasket tape. Not sure if that would be worth it though. Also adding R13 to wall and R19 to ceiling.

I'm debating if I should use DC-04 clips to separate the walls from the top joist. The cost is about $250 for them but not sure if the added benefit is worth the cost. The house is two floors so there is 1 floor between the HT and the bedrooms. So I'm not sure if the clips would make any difference in sound traveling to second floor. Not concerned about sound on first floor just second.

Thoughts?

To be honest sound proofing is all or nothing! You cant do just part of it and get sound proofing results because of flanking. Its like trying to put water in an object with a hole in it.

Best thing for you to do before even doing DD is give Ted a call and ask him what your options are. He wont BS you in any way. He will tell you exactly how it is whether he is going to make a dime or not!

I hear you, I was just thinking that something is better than nothing. The DD will definitely help some just wasn't sure about the GG on the joist/studs and the DC04 clips. I sent him a message a few days ago, waiting to hear back.

Waiting to hear back from me???eek.gif Geez, sorry!

Green Glue on studs and joists does nothing. Save the cash. Foam Tape is equally worthless. Best budget tactic would be to install 24" OC framing. If you have 16" already, just add wood or metal furring at 24" OC spacing, then add the drywall to that.

This isn't decoupling, but the 24" spacing is much better than 16" for isolation.

Standard fiberglass insulation everywhere is good.

You might try this with single 5/8" drywall and give it a test run. You can always go back and add another layer of 5/8" with damping if you like.

I could have sworn i sent you a message via PM. The basement is unfinished so 24 OC is possible just need to run it by the inspector. Thanks for the info.

Pretty sure he was just commenting on how busy he is and PMs would be the slowest way to contact him.

Actually, I'm just a poor PM organizer. No slight intended

Do you think it's worth doing puddy pads and acoustical caulk on all the edges? Other than the insulation and DD that is the only soundproofing that's within my budget. Just not sure if those two items are worth it.

You have to seal things up, but you can use sealant or a putty pad.

OK, I'll get some Sealant and putty pads. I guess you sell these as well. Could you send me a quote via PM? I’ll be sealing the perimeter and corners of a 30x11 room. Will need about 30 putty pads.
