I feel like a broken record (vinyl records used to skip or get hung in a groove & repeat endlessly.....Ahhh, the good old days).......what about the box stuffed with whatever flame retardant insulation ? I would really like to be able to stack these things up to build movable isolation. Using stuffed a heavy cardboard box that computer towers come in, worked for my friend in his studio......I just want to know everybody's thoughts. You have talked me out of using old clothes.......using insulation instead, but WHAT ABOUT THE BOX?
thanks!

It might help some, but isolation in general is all about mass. Obviously, a cardboard box doesn't have much in the way of mass.

Let's not forget isolation and absorbtion are two very different things. Mass IS the only way to isolate sound and prevent it from escaping. If you are trying to absorb sound within a room to calm a resonance there are lots of materials to do that.

Check out this chart.

Regular fibergass insulation does a great cost effective job of it. Just cover it to provent the fibers from floating around.

Oh yeah;

The International Agency for Research on Cancer (IARC) completed a re-evaluation of the cancer hazard of synthetic mineral fibers, such as fiberglass. The panel concluded that the cancer risk from fiberglass is "not classifiable." This reverses an action taken in 1988, in which IARC concluded that fiberglass was a "possible" human carcinogen.

A good link in case you may not know.
