What about Insulated Concrete Foam walls? A local company, Rastra, makes whole buildings out of that stuff. I only know of them because we take the truckloads of foam that our insulators come in to them for recycling. Great product though and should more than block any noise.
Not sure how expensive it is now but when I was working construction back in Texas we found that having exterior walls made of that plywood laminated foam at 6 inches thick and 12" ceiling(they put 2x12 beams in them) came out to only a fraction more than typical building after labor is calculated in. It's stupidly fast too. Foundation poured and set and 2 days later the roof was being put on. Even had the window and door holes pre-cut so we started laying things on the foundation Monday and by Friday it only needed half the siding left to pass as a real house(if you didn't look inside). Mind you, this was a 5 guy team that only contracted out the siding work but unlike traditional building if you decided you wanted an extra window you were SOL.
