looking to seal metal boxes

what is the best way to seal the holes and cracks in metal junction, outlet, and switch boxes (drywall is not up yet so they are exposed). i'm building a home theater in the basement and to reduce the amount of noise that can leak out to the rest of the house i am trying to make the room as air tight as possible.

also, once the drywall is up, is it ok to caulk the gap between the drywall and the edge of the box?

Are you saying that, that 1/4 inch hole in the back of the outlet box is a problem?

I had to use box extenders due to the fact that the room will have 2 layers of drywall plus an additional inch of trim. It's the gap between the extender and the box that I would like to seal. Because the back of the extender is radiused, there's about a 1/8" to 3/16" gap all around except the two corners where the screws are.

I would probably try using metal foil tape on the outside of the box (definately NOT inside the box). I would think the caulk is fine as long as it is also NOT inside the box, but just along the edge.

Dude, If you can hear the differerence in the systems more power to you.

However this is not a question for the electrical forum.

We only care hear about the electrical side, not the sounds it makes later.
