Okay...false start. Let's try again.
Hey guys! Okay, so I have my little rehearsal space, in which I've been doing some recording. So far everything seems fine. There are problems sure, and issues I'm working through, but so far I think I'm feeling pretty okay with all of this.
My question is about the treatment on the inside of the room. I am in no position to drop any amount of cash on acoustic tiles or bass traps, but what I've done can be seen in the pics below. The tiles are 1/2 thick closed-cell neoprene. I've noticed a drastic improvement in the sound of the room, which was sounding like the inside of a bouncing basketball, but I'm wondering...are my inexperienced ears missing something?
Again...everything sounds "fine" to me, but I rarely if ever see this sort of symmetrical checker-board pattern I've implemented. So, what I'd like to know from some really experienced 'acoustic engineer' types... how #@$% up is my set up?
I recognize, there are countless variables, and without being in the room, no one can tell me exactly what I need, but I'm looking for the theory, the probabilities, the 'hey watch out fors'.... Know what I mean?
The room is 10x14x8. The walls are 8" cinder block covered in 2" closed-cell neoprene. Then there's a 4" void and 5/16" OSB, about 40% of which is covered with 1/2" thick foam. Two opposing ceiling corners have 24x30x2 panels of neoprene and one other corner has a 6' neoprene wedge. Along the long wall, and centered opposite the DAW, I have a 4'x6' curved diffuser. It's behind the Sabian banner. The ceiling is covered in a loose, draping, heavy fabric similar to burlap, but thicker.
Any advise or observations would be appreciated.
