Hi,
I’m wondering if anyone has real world (or theoretical knowledge) with sound booths or professional level sounds proofing could offer some advice?
Long story short: completely modular sound isolation booth. End goal is 110db inside booth, with the volume outside low enough to not escape a standard dwelling unit. Primary requirement is the ability to easily tear down into transportable, albeit heavy, panels. Secondary requirements include modular size changes and a reasonable budget (<$2000 w/interior treatments).
Regarding my construction, I have two main configurations mocked up:
1. individual panels are butt joined, with MLV on all joining surfaces.
2. Individual panels are offset and lapped, so the joint has 4 90* corners, with MLV on all mating surfaces.
All panel joints will be drawn tight with compression on any MLV.
Given there will be a good amount of panels comprising this thing, I want to avoid having minor sound leaks from seams add up to huge transmissions, but I also don’t want to put that amount of effort (the offset complicates finishing significantly) if a proper butt joint will suffice.
Total depth of joint would be about 5”. I imagine if there was a box of 5” MLV it would suffice in its own, so maybe tight butts (oh yeah
) is the way to go?
Thanks for your time, just throwing this out there to see if the CP brain trust can advise.
