I was reading nrc nrcc44764 and was attracted to fig. 10 pdf page 9. The densities varied significantly. It reminded of the USG Report on wall insulation density. I could not find the report though. Where is it? I feel blind not being able to find it. :D

i've only seen some testing where they used 4.0 pcf, and 2.5 pcf (construction guide and a couple of other docs) but i think i do remember a more elaborate report on acoustical properties... just don't know where it is... probably on my old desktop and not my laptop... :?
