At SPR they make the assumption that the thicker the substance is, the better it is as noise blocking, but I'm not sure that's sound logic.
It's a scientific fact, is t not, that noise, like heat, travels more quickly through material with a higher density. So, as far as transferring noise, lower density would be better. What I'm not sure about is the blocking of noise. If the assumption is that the thicker material would stop sound in its tracks and so the transferance is rrelevent, then you're essentially saying that the noise would bounce off or reverberate off the insulation.
The bottom line, is that I'm confused about the scientific principles behind accoustic insulation and was wondering if anybody here knew some facts they could share.
