Acoustic foams generally are very bad for the sound, the most agregious example perhaps being SONEX, the worst scam ever perpetrated on gullible naive audiophiles. Another prime example is the IKEA Puang foam-filled chair. It looks like such a nice inexpensive comfortable chair, too. ๐ is Memory Foam an acoustic foam? Who knows? But it looks too close for comfort. Maybe if the Memory Foam is NASA qualified. ๐
A thousand audio uses for memory foam. Or maybe just one . . .
So i have this old memory foam topper for my bed, and before I cast it off completely, the DIY part of me I got to thinking, could it be used for acoustics in any way? I donโt have the slightest clue as to the frequency it would be good at, but cutting it into various rectangular shapes and sizes first comes to mind. I could glue them to some plywood and diffract and/or diffuse sound.ย
Any other thoughts or suggestions?
