Hi gang, I live in Las Vegas & 1 of the big Night Clubs is remodeling & getting rid of some large absorption panels. They measure 8' x 4' x 2" each. The material looks familiar but I'm not sure what exactly it is...The frame is made of a composite of wood shreds that look like spaghetti thats formed into boards...very porous & a bit heavy. I vaguely recall seeing this material in school, maybe in my old band room. Each panel has 2 sections / troughs with a rigid yet porous material that acts as an absorber. It's not foam, but some kind of fiber material appx 1" thick.

Can you identify what materials are used & how affective they may be when used as absorption panels in a live room?

See Pix ;-)

I'm having trouble uploading pix..In the meantime here's a dropbox link to them...

Thanks in advance.

I have seen that stuff before, but I-m not sure what it is. I seem to recall that it is some type of compressed cellulose product, but no idea what the acoustic properties would be.

Sorry!

Thanks Stuart :-)

Anybody else have any ideas? I'm sure it must look familiar to a few of you...

McDonald's here have ceilings like that. They are tiles of cement impregnated wood shavings.
Celenit is another brand name.
I keep an eye on products, particularly Eco ones. Polyester fibre made from recycled plastic bottles is springing up all over EU and Australia. I have heard of no American version. The absorption figures are probably the best I have seen.
