Sound proofing new residential

[zazzaron]

I am about to build a new home. Some sort of sound proofing would be nice on the interior walls. Does anyone know of any new products or techniques that could be used at reasonable cost.

Good old fashioned fiberglass batts seem to do pretty well, and are likely to be as cheap a solution as you're going to find.

SAB, Sound Attenuating Blankets, which are slightly denser than standard glass fiber batts are a start.

Look at Flanking Paths: electric boxes back to back within a stud space, gyp board not sealed at the edges, ducts that give a path from space to space.

In that regard, one of the most effective techniques, albeit somewhat more expensive is to use 2x6 baseplate w/ alternating 2x4 studs so that there's a break between the two walls.

Not really.. but here are some old faithfuls:

I've been in some labs with sand-loaded walls -- nice and quiet!

I have vinyl siding over 3/8" foil faced polystyrene panels over the plywood sheathing, 2x4 walls with fiberglass bats, plastic vapor barrier, and 1/2" sheetrock. I can't hear vehicles going up and down my street about 90 feet away. The only time I know I have visitors pulling into my driveway is when the yorkie barks, or the people ring the door bell. If I had my druthers back then, I would have had them put in 2x6 studs for better heat insulation. That might have helped my fuel oil bills today.

2x plate with separation between plate and studs. Alternating studs is important. Foam tape at plate and floor(under plate and above plate). Blown in insulation....Water based.......Used in movie theater and honeymoon sweets.......(foam that hardens then is shaved off.) Cheaper is batt insulation. Some wall we sheetrocked 2 layers both sides.....with stud separation Yes, electrical, and such boxes need attention with spray foam.... Important aspect is the transfer of sound waves through solid material. Avoiding this will lessen sound. jloomis
