would this design idea work?

trying to make a portable type of wall, for if and when i move.

i was thinking to make 2 gobos that sorta create a double wall that floats infront of normal walls.


basically one wall would be just 2 pieces of ply would that hinge and give me an angled ceiling type tihng. what would be good to make that out of? ply wood?

i would then treat the surfaces with acoustic foam and place them so they'll trap frequencies behind them between the walls.

here's my graphic representation...

I think just hanging broadband absorbers on the existing wall (that you can take with you when you leave) would be more feasible. As for the angled wall you can accomplish the same thing by making a wooden frame that you can screw (not nail) into the existing wall and stuff insulation in it for bass trapping. I'll draw what I mean and edit this in a minute. Be right back...

Alright, how's this? Just screw the 1x4 plates to the wall and ceiling studs then screw the diagonal 1x1's every 24". Load the cavity with 2'x4' 703 and staple up some burlap to cover it up. Get the idea? When you move just unscrew everything and redo it at the new place.

I picked up a bunch of foam panels where they had taken 1 inch stiff construction-type insulation (not 703 rigid, but that blue stuff they attach to the frame of the house before putting on siding or whatever) and then glued the acoustic foam to these panels. They are mostly 4x8 (with a few 4x4) and pretty portable, I generally just lean them against the existing walls and can use them to form a smaller "isolation" (quites because is it only a partial isolation at best) room within the room. I doubt they do much for LF absorption (have bass traps for those), but they do great for reflections and HF absorption and are very portable. Since they are really big panels, when they are leaning against the wall (with the 8 foot side running vertical) they essentially cover the entire wall and don't even look very bad, pretty uch like a wall of foam.
