flooring and walls

[timotheus]

I have been perusing posts about soundproofing and acoustics. I am curious if anyone has ever used or has any thoughts about using the foam tile flooring that is used in gyms and playrooms? I was thinking of using the 1' x 1' or 2' x 2' puzzle pieces for floors and walls. Comes in 3/8" and 1/2" thick tiles. It is fairly dense. I am still working on designing based on tips and tricks I am reading in the forum for acoustics and soundproofing.

Any feedback is appreciated! Thanks!

It may give some isolation, like if you put a sub on it the floor may experience less vibration (good or bad thing, you choose), but I think it would provide little reflection absorption. You would still need acoustic foam tiles or DIY tiles to absorb the reflections on the walls/ceiling.

But I don't have the experience many here do, so take it with a grain of road salt (much bigger than regular salt...)
