[QUOTE="captainobvious!, post: 8345559, member: 546920"] Very nice attention to detail in your build log, it's a pleasure to read. A couple of things- first, I was under the impression that Ensolite is actually OCF (open cell foam) not a closed cell foam. If it were a CCF, they wouldn't advertise it's absorptional properties- or at least it wouldn't make sense since CCF is a very poor acoustical absorption material, whereas OCF [I]can [/I]be decent. I like the product and find it to be very useful for decoupling panels, but the fact that it's very thin makes its usefulness as a sound absorber very poor for anything but the highest frequencies. The PSA stuff rocks though for panels like you've used it here. For a true CCF foam, I like the neoprene from TheFoamFactory.com. reasonable prices there as well. Next- Can you explain the fiberglass batt/ceiling tile pieces that are used in the doors and what their purpose is? Doesn't sealing them off in plastic eliminate their sound absorption properties? What effect do they have installed in the doors like this? Is the casing acoustically transparent? To what degree? Also, how waterproof it is ? Seems like a ****** idea if it's actually effective. Definitely digging the denim batting. That would be a good thing to install in the cavities of my Mazda to reduce some of that noise. I'll have to take a look for it. Also, is thi smaterial more effective as a sound absorber than the fiberglass insulation? If not, would it then simply be better to use your door method? Thanks! -Steve [/QUOTE]
