Anybody have any info or links on the acoustical properties of soundboard/fiberboard? The compressed fibrous 7/16" material common in house construction/roofs.
I'm thinking mainly of absorbtion characteristics as apposed to TL data.
Is it considered a resistive absorber? reactive absorber? or not much of an absorber at all?
Thanks.

Check out "sprayed cellulose fiber" charts near the bottom, that's about the closest I found... Steve
