Foamular extruded polystyrene insulation?

Hi all,

I'm hoping some can give me some quick perspective regarding the above as a means of sound absorption. Does the pink Corning "EPS" insulation work as an alternative to rigid fiberglass to absorb mids and highs? Just curious. Guess I'd have read a lot about it if it were good, but can't find any info one way or the other. It seems like it might be too dense to absorb. . . but what do I know?

Thanks in advance for any comments.

EPS, or expanded polystyrene foam, does nothing -- zero, zilch, nada -- as far as absorbing mid- and/or high-frequencies in any useful way. Makes nice thermal insulation in a wall, and, if used in a sandwich construction between layers of sheetrock it can aid in lowering sound transmission through that wall. But it will not do doodly-squat as far as acoustic treatment within that room.

Thanks Bob. That's was the answer I thought I'd get. Just wanted to know. Thanks for your comments.

Polystyrene and chipboard

I was thinking of building a small drum riser for my home studio,
Instead a friend recommended a thick polystyrene base and chipboard on top, then a carpet, and finally my drums.
Any thoughts on if this would be ok.
The purpose is to try to eliminate as much sound as I can because I have neighbors below me :-)
I realize they will still hear the drums, I just wNted to try to minimize as much of it as I can.
It's a small recording studio in a small room.
