my question has to do with coverage. with a mass loading type damper why does everyone cover every square inch with multiple layers? Wouldn't you want to just add enough mass to lower the resonant frequency below 20hz and then add a layer of decoupling foam and then a layer of mass loaded vinyl to finish? Seems like a lot of additional weight without much gain. A panel is not going to vibrate as much with a bend in it. Also, how much do you guys spend on this stuff? I have a regular cab truck that is my daily driver. I have a very small system to install. So far I have 2 price quotes for just materials that are over $500.
