Hey all, I did a photo shoot at local school, and in their music rehersal studio, there were some panels glued to the wall, presumedly for sound absorption. They were were 2'x4'x2" and looked like, well, angel hair pasta squished together. I'm thinking it was some sort of fiberglass. They looked like they might have been industrial ceiling tiles.
I did a search online and couldn't find anything similar.
Anyone know what these are based on my lame description? If so, would these be a cheap way to tame the slap echo in my space?
