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

I had heard that staggered stud construction was good for isolation. That's what I did.

1. Studs should be 16" on center.
2. Use 2X6 lumber (Good, but not essential).
3. Apply 1/2 inch sheet rock.
4. Apply a layer of styrofoam (or other lightweight plastic insulation panel). One inch thickness is fine.
5. Apply another layer of 1/2" sheet rock.

5/8 sheet rock is to avoid sags between ceiling rafters which are on 2 foot centers.

Be sure the studs rest on isolation materials at the header and base strip.

I'm looking at dedicated room but I have challenges with the main water line. The main water line along with the cut off valve are on the primary wall where I need to stud and sheet rock for AC and placement of components and speakers.

The water line sticks out from the concrete wall a good 7 inches so if I stud the wall I would have to move the cut off valve to different place for access.

How would you approach the problem?
