Going to purchase a longmill(30x30) this week so I’m getting materials ordered for an enclosure. (acrylic sheets are difficult to find locally these days). I’ve attached a Sketchup of a rough design. I’m going back a forth about this design or an under the table design. I will be putting the machine in my basement storage/workshop room directly under my 3 year old daughters bedroom. Im planning on putting insulation in the floor joists and might even strap/drywall ceiling. I want the inside of the enclosure to be bright as my basement is quite dark, so i’ve ordered some led strip lighting. As for the sound proofing I’m looking into either rigid foam (pink) painted white or the black foam acoustic panels from amazon (which would be dark?). Im also going to use a small shop Vac for dust control but for the time being will just box it in until i can set up some real dust control. Im hoping that someone has had some experience making the machine quite as my two kids do not sleep enough as it is…and my wife would not be happy with me waking them up!
TLDR: Which sound proofing would be better: pink rigid foam board or black acoustic panels.
