air compressor enclosure
« on: February 26, 2015, 02:39:37 PM »
I am thinking about building enclosure for my air compressor according to your plans (3 boxes).

Now I have a heap of  small scrap rock peeces (granite, marble and the like). They are 8-15mm thick 50-100mm long, and 10-30mm wide.

I was thinking, if mass is a good thing for stopping sound, would it make sense to epoxy those small peaces to the mdf in some random manner?

if so, on the inside, outside, or both? Does it make sense to put acoustic foam over it?

Or this is yet another example how people who do not know acoustics have rather bad ideas? ;)

mass needs to be equal through out the system..remember that sound will always go to the area of least resistance.

heavier the box that is lined with a foam mat will perform the best.

So the effort to collect those stone scraps was wasted, but at least I will not make box that is heavy but does not block the sound well.

Thanks!
