I have a very similar situation to gamba.
Not to hijack this thread, but maybe in taking a look at my situation and some ideas I have, we might both come up with a solution (without starting another nearly identical thread).
I'm a full time freelancer (copywriter, producer, voice talent) with a roughly 14' x 22' office space in my basement. It's a multi-use space, also serving as my music room, recording space, meeting area, paste-up/mechanicals, etc. My audio work is mostly simple voice overs, with occasional acoustic guitar/vocal recording for my original songs (strictly a hobby). The room itself started off as a rec-room, but is now my office. It's cedar paneled all around, with a drywall, texture painted ceiling (pebbles). As long as my furnace or water heater doesn't kick on, it's a pretty quiet space...just boomy, because of the paneling.
I want to set up a recording "booth" for voice overs. Looking to deaden the space, but don't want to build anything permanent. Nor do I want to treat the entire room.
I need opinions on whether what I have planned will do what I want it to do.
I'm thinking of building a set of freestanding gobos to surround the vocal booth area. Like a pair of trifold absorbers set in front of, and behind the mic. Thinking of (3) 2'(w) x 4'(h) panels made from 2" thick OC 703, set on height adjustable stands. The panels would be positioned like a "C", angled out at the sides. Like so: \__/ 3 panels in front of the mic, and 3 panels behind, creating space for the booth.
I don't really need to completely deaden the space, just reduce the liveliness of the room. A "close enough" solution.
First, do you think it will do what I need it to do? Should I put a hard barrier (like masonite) on the back side of the panels? I also have some (of what I assume is) acoustic egg-crate foam in 2' x 2' squares. Plenty to cover the exposed 703 surfaces. Is there any advantage to layering the foam on top of the 703 for extra absorption?
Any thoughts would be greatly appreciated! And sorry about barging into your thread, gamba. ;-)
Thanx!
