Double width studs for isolation?

Before I drywall my new dedicated room I was wondering if it would be at all beneficial if I added an extra stud to each/some of my 24" on center studs to increase the amount of surface area the drywall was screwing into and thereby conceivably decreasing the "intensity" of energy transfer through them into the outside walls? My goal is to reduce noise transmission through the walls. I will be using 2 layers of 5/8" drywall with Green Glue between. It's not a lot of extra work and I already have some extra studs. Just a thought. Thanks. Grant

Also, I've never seen it in a store, but on some home reno shows on HGTV, I've seen a new type of sound absorbing drywall. It's a bit expensive. I believe it has a sheet of metal sandwiched between layers of gypsum. It might work through the stiffening effect that Nsgach noted. Maybe you can find it somewhere. Try the websites for drywall manufacturers.

Lissnr,

Did you check out the QuietRock 525? One layer of the 5/8" thick 525 is equal to 8 layers of standard 5/8" sheetrock.
