But even the high-density stuff allows sound waves to pass through. That's what attenuates them. So you need "holes" of a sort. If the sound waves don't go through at all, they are reflected, which is exactly the problem we are trying to prevent.

My guess is that memory foam isn't sufficiently "porous" to attenuate the sound energy like you want. It may absorb some but not nearly as well as the standard panel materials.
