Vocal booth floor:
This just illustrated how I did the flip-floor a little better. The hinges usually don't come out well because they are shiny and the digital camera freaks out with reflections.
Anyway, the flipfloor allowed me to put my vocal booth over a rarely used stairwell that goes to the garage, thus maximizing space in the control room. I'll have much more space once I clean out all the crap on the floor as well as the junkpile thats starting to accumulate in the corner next to the booth.
You can also see in the picture (upper right) two bifold doors. I simply hinged them together, so all four doors attach on one side, slide out, and slide back. I had to do this for two reasons - the vocal booth door is right in line with the center pillar of two windows (one I have to cover with an indoor, insulated shudder for acoustical treatment, haven't done that yet), so I couldn't hinge anything on the window side. This was my wife's idea, kudos to her. I have all the carpet remnants and have started to carpet the inside of the booth.
The walls are made of dense plywood (three layers, with 1 layer of rubber in between) screwed to 2x4 studs. Its not staggered stud construction, but rather a very simple box. The thickness of the walls is what keeps the sound in/out, even though the doors don't fit tight at all. I'm going to be installing rubber flaps over and around the door bodies so that it seals up better when closed. Since I record everything dry and neutral and add EQ and such during mixing, I can record with headphones so I only have to block out machine noise and hard drive noise, which in its current configuration the vocal booth does well. Some flaps for extra protection etc.
The only noise I haven't been able to block out is the garage door opener underneath. I tried re-mounting it on 1/4" rubber pads however it still vibrates the floor joists of my studio, so I finally installed a "wife cutoff switch" which just cuts power. Only need this when I'm actually using the booth.
I said I thank you very much, and will be loading autocad this weekend on my laptop once I find the power supply for it.
