Okay, this is my FINAL (maybe) idea.

My wife has put the kybosh on the 12x10 iso room, and given her current state of babydom...I'm not going to argue. If Mom's not happy, no body's happy. So, here is option 2. Space saving so it will work in my basement space. Seems like it would be 'enough' for what I need unless there are people with serious objections based on expertise. The current room is pretty quiet. I can record in it with minimal treatment (blankets on the windows and such). Based on the following chart examples, http://www.acousticalsurfaces.com/acous ... 101_23.htm, I would say the room is currently a 42 from outside and about a 32/35 from the rest of the house. I know it would be relatively cheap to use 36" luan door panels (about $25 ish) for the walls, frame it with 1"x1"'s and securing it with screws and liquid nail. Then fix Gypsum (drywall) sheets to the outside and inside. I was even thinking of using Green Glue (or equivalent) between the door/drywall contact surface. Seal it up with acoustic caulk and attack a solid door to the front of it. Overhead would be either same construction or just heavy plywood with insulation. Interior would have all the trimmings (treatment - foam, light, venting). I was even thinking of experimenting with sound blankets instead of foam (cheaper and less space). Any adjustments or 'absolutely don'ts' I should be aware of?

Aloha and congrats on the pending babydom arrival, A couple of points to consider, perhaps: - quiet is good, especially with the pending new arrival - it has been mentioned on the construction forum that 2-3 layers of 5/8" drywall is still the most cost effective mass you can add to your studio construction - most prescriptions for acoustic treatments prescribed here call for a semi-rigid insulation (rock wool/OC 703 types) @ 2.5-3 psf rather than foam or blankets. Here are a couple links that might be helpful - http://www.johnlsayers.com/HR/index1.htm http://www.saecollege.de/reference_material/index.html Finally, any pics so we can see what you're describing?
