A good friend of mine turned me on to a product called Mineral Fiber (Made by Owens).

It is like the pink stuff (only it's yellow), but much better.You buy it in bales and each bale holds about twenty 3"x24"x48" panels. It is placed between the studs, and assembled cloth panels are placed over it.

When we had finished framing the room, i began laying in the fiber between the studs. As we progressed, the acoustic properties of the room began to obviously change. Here is what my crew noticed:

1. Increase in intelligability
2. Outside noise drastically began to disappear
3. Room beacame a bit cooler

Most AC Supply joints should carry it.

It is also fire resistant.

Cheers
