I have searched around the site and found some helpful insight on this. I am throwing around the idea of building the walls in my studio with straw bales. It seems people think that it would work well for broadband absorption. I am curious however of what kind of isolation a wall like this is capable of? Would it be sufficient enough for isolation between live and control rooms? How would it compare (isolation wise) to a double wall with staggered studs, air gap, rockwool and 2 sheets of drywall on each side?
I am new here and have found so much useful information. Thanks in advance for everyones input.

I saw that thread it helped a lot. The fire hazard part isnt an issue. They have tested the walls and they are more flame retardant than most standard construction. They are so airtight that there isnt enough oxygen to burn. (so they say)
I found an STC rating for one certain house built in Idaho I believe. They stated that it had an STC of 57. We all know a double wall with 2x4 studs, rockwool, air gap and 2 pieces of 5x8" gyp on the exterior walls is anywhere from STC 58-63 or so. Any ideas of how to make the straw bale wall up around STC 67 without adding much more mass to it? The suckers are already going to be huge as is. Thanks again.
