Using mineral wool to deaden but keeping it covered well.

I have a vocal booth/dead room about 6' x 6'. I want it as dead and as flat as possible with what I have.

I have (3) 54" x 54" 2" cone foam sheets from Markertek and (4) 2'x4' sheets of 2" mineral wool left over from some slot resonators that I built in the other rooms.

I've got the 2" cone foam sheets stapled onto 3 walls now, and it is OK when singing/quiet, but you can hear the room when you start singing loud.

I would really like to use the left over mineral wool that I have (man this stuff absorbs!!!) but if you just tap this stuff even covered with burlap, many tiny pieces of fibers come off, and this stuff is nasty to your skin/lungs.

How can I use this stuff to make my room dead but still cover it up completely so fibers dont become airborn?
 
MN,

Cover it with something less open than burlap. Any soft material is fine. Just avoid shiny fabrics like silk and synthetic equivalents.

Thanks Ethan.

Can you recommend anything in particular - that almost nothing can get through(except sound of course).
 
What is the best way to mount this stuff on the wall, so people dont run into it?
 
Mounting it on the wall and keeping people from running into it seem like two different problems. :D

To mount it on the wall, you can make a wood frame around it and hang it, or screw through it with bumper washers etc...

To keep people from running into it, just mount it by impaling it on sharp spikes that are 3" longer than the stuff is thick... :=)

Seriously, though, I don't let anyone into a vocal booth that was born in a barn or dumpster - they need to understand that this is a recording studio, not a nosh pit... Steve
 
I thought of something.

I could use use a metal grate(along with the fabrics as suggested), you know like what they use on amp cabinets. Anyone done anything like this? Anyone know where you can pick these up - like bigger ones?
 
another alternative is plastic sheet - i.e. the stuff you use in gardens or as a vapour barrier. Yes it reflects the highs and the rest goes through and is absorbed but it keeps some high end in the room that stops it from sounding totally dead. It definitely stops the shower of fibres.

John, even though you're right, I STILL like the SPIKES... (spoken through hideously evil grin...
