A thousand audio uses for memory foam. Or maybe just one . . .

I love memory foam i have a pair of electrostatics and i use the foam for back reflections from my panels and the speakers disappear into the room.then i put on MARY JANE a song by RICK JAMES and we dance the night away!!!!

Earlier I had a great idea for you and that memory foam, but I thought I would sleep on it....

I’m not sure what this adds to the discussion, but a couple of years ago I got a new bed.  It wasn’t memory foam but rather latex over individual coils.  Incidentally latex never breaks down, unlike all types of foam.

The queen size mattress was made of 2 side by side latex pieces to allow different firmness on each side, but I could feel the gap and they sent me 1 huge latex piece to replace the two.  Before I sent back the latex pieces, I tried one in the corner of my room.  It had lots of small holes.  It definitely seemed to absorb bass and inquired what it would cost to keep them (I was secretly hoping the company would forget about picking up the now slightly used latex) but they indicated it would cost over $800 for me to keep the pieces.  I Don’t know if anyone has ever experimented with latex as a sound treatment, but it seemed like to had potential.

last_lemmingvery interesting query. We know that some speaker manufacturers use cotton or wool in their cabinet designs. Perhaps memory foam could be the next anti-vibration, sound absorption, evolution? I look forward in reading about any experiments conducted.

Happy Listening!

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. 😛 is Memory Foam an acoustic foam? Who knows? But it looks too close for comfort. Maybe if the Memory Foam is NASA qualified. 😀

Cut a piece exactly 20x14. Cut another piece exactly 14x10. Wrap them in a neutral color acoustically transparent fabric. Place on ottoman. Very comfortable.

If you leave it flat, it won’t do much, but(perhaps) absorb some very high frequencies. If you raise portions into waves, rather than cutting it up, you may be able to use it for absorption/diffusion. ie: If it’s big enough: maybe a couple for your early/first(side wall) reflection points. Or- if you’re seating close to a back wall, use it to kill the reflections behind your head.     Finding reflection points: https://www.youtube.com/watch?reload=9&v=Oa5vfEIXyok

Try different small shapes and sizes... 2x2x1, for example,
and even smaller than that.

Place on components, at the end of cables, speaker cabinets.
Experiment with different foam pieces as headphone pads too.

Different sizes, weights, and foam densities will yield different results.
Even try the stuff that is used in packaging.

You may be astounded at how foam can tame micro vibrations.
Think small.
