Wanting to build a quiet noise-isolated room for sleeping and jamming(guitar). What materials are easily available that will block sound? Would this stuff work?
I was thinking that, but in a 2" thickness. I live near the factory, and could get seconds for very cheap. Would it do well if combined with something like masonite for sound reflection? That is more sound dampening. Would it be useful to put in that pink cotton candy type insulation stuff? Like, would the pink insulation do the same job, but less efficiently, or a different job altogether? Maybe a Layer of 1" R-Max, a layer of pink fibreglass, another layer of R-Max, and then the hard board? I really don't know much about acoustics.
