If you want to do a soundproof enclosure, you need to do it like you would build a 'soundproof' room. Just in a smaller form.
The DIY 'sound studio' type of thing can be in a frame room, with a acoustically insulated floor (not touching the floor below it, using shock absorbers/dampeners, sound absorbing material (not concrete or linoleum!), walls are heavy. You can use sheet rock, some cover it with lead sheets - yes, sounds goofy, but mass reduces sound transmission, then hang ANOTHER sheet of sheet rock over it with acoustic hangers, they look like Z shaped strips of metal, with one end attached to the outside wall, and the opposite side attached to the inside sheet rock. Yes, acoustic dampening helps, in vents make them serpentine covered INSIDE and out with sound absorbing material (rock wool works OK). -- No bolts or screws or supports on top of each other that gives sound a direct chance to transfer from the 'inside' to the 'outside' without having to zig-zag a couple of times before getting out! NOTHING should be hard attached through walls or floor to the outside structure. For those that don't want to go that far, http://www.instructables.com/id/Build-your-own-soundproof-studio-in-11-easy-steps/ shows how to make a 'garage band studio'. Another link: http://www.diynetwork.com/how-to/rooms-and-spaces/walls-and-ceilings/soundproofing-a-wall An another: http://www.backtoplastic.com/?page_id=85 >From those you will get a hint as to what makes 'soundproofing' work. It isn't easy or cheap. Several folks here (near Nashville) have professional quality studio's built in their basements, With studio, separate sound room for technicians, all insulated from the rest of the house. Yes, they go to extremes, but that is their livelihood as well as passion. I haven't build a 'CNC SOUNDPROOF ENCLOSURE' but that is why I started researching it a long time ago. Distance, mass, reduced reflection, and absorption are all part of the equation. Keeping down transmission through the ground and walls is also important. You can also 'tune' your sound reduction to frequency ranges. I hope this helps someone a bit. ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
