I had this idea.. Since we all know that noise is vibrations in a conducting
matter and the basic idea behind every dampening material there is is
to either reflect this noise or convert it to some other form of energy
(heat for example, using friction). Would it be possible to effectively
combat noise by creating a set of panels with a complete vacuum inside
them, so that the air would not conduct the noise? I mean, like a side
door divided into compartments, that are then sucked airless? Anyone
know physics well enough to shoot this crazy idea down? The only thing
conducting noise then would be the joints of the panels enclosing the
computer, and those can be dampened quite effectively with, say, rubber?
Man that would be expensive to produce
Vacuum paneling to stop noise?

It might work in theory, in practice it would probably be a bear to build and maintain the vacuum in. I suspect that unless you used really thick panels, you would have resonance problems - The vacuum would stress the panels making them into very effective diaphrams. I would be more inclined to look at making a panel with some kind of sound absorbing foam core as opposed to a vacuum.
