the double wall Larsen/Riversong truss systems is a solid performer as well.
After hanging around Mr. Riversong on another forum, I must admit a much "greener" option to boot.
After living/working in our house for a few months now, I can tell that the sound transmission through the foam is very high...too high for a house IMO. Originally I was going to leave the wall cavities empty, now I'm planning on blowing dry pack cellulose (damp if I can find the equipment to rent) in them in order to reduce the noise transmission and as a bonus, bump up the insulation value to about R46.
