How well would this work?

I was thinking today about the problems of the AVERAGE home recorder who may not have a room that can be premanently dedicated to recording and might even be renting. (and are saving for a new microphone rather than planning thousands for construction)

This this idea hit me. I know its not perfect, but how well do you think it would work.

1. Take three sheets of the famous owens-corning 703 rigid fiberglass two inches thick.

2. Cover them in the preverbial burlap cloth, then connect the long edges to make a Z shape panel 4 foot by 6 foot fully open but foldable to a 2 by 4 stack 6 inches deep. The unit would weigh only a hair over 12 pounds.

3. punch two holes slightly in from the 4 foot edge, loop a cord through each and hang it from the ceiling. Since it is light you should only need some fairly lightweight hooks to hang it from. So you have a hanging 4 foot wide by six foot high sound absorber.

4. Do the same thing three more times to make yourself a 4 by 4 foot recording place surrounded by these sound panels. If the panels are flapping and bumping secure them to each other using velcro. If the floor is a hard surface then use a pad or carpet remmnant.

Now obviously this idea is not perfect. Sound will be getting out and in above, below, and between the panels, but the quantity of sound that will escape, bounce around the room, and then get back I would think would be greatly reduced over what might otherwise be able to be done with working in a room that still has to be used for its original purpose too. The obvious virtues of this idea is that it would only cost about a hundred dollars, could be taken down and packed into a 2 by 2 by 4 foot space in a minute, and would require no more construction than eight small screw holes in the ceiling.

But what I was hoping for your opinions on, was whether it would help enough to be worth doing?
 
i built something similar, a 4x4x7 little booth with walls, ceiling and floors made out of foam.

the problem was that it was so dead that it was impossible to sing in it. i think it was probably just too damn small... lower frequencies didn't have a chance to develop in that space while higher ones were completely absorbed. the sound you get in a mic from a COMPLETELY dead space like that is thin and shitty at best. it made expensive mics sound like absolute crap.
needless to say, it's been dismantled completely.
 
Too dead? Hmmm, here I was in the impression that for tracking you wanted the deadest possible space. This tells me that this kind of hanging absorber would work, just don't completely enclose the space.

So this brings up another question. Presuming that you are recording mostly vocals with a cardoid mic in an average room where is it best to add sound absorbtion? Behind the mic (because that is where most of the voice will be first going) or behind the performer (because that is where the mic is most senditive) or to the sides (because sound from those directions is almost certainly reflections)?
