Buying Sound Proofing tiles on Amazon.

Title says it all, I am doing better than I thought with my VA stuff.

Initially I was going to buy acoustic blankets and just lay them over my PVC frame, but now that I am booking work consistently I want to just make the frame sturdier with wood.

I also am considering doing soundproof tiles on the inside, but are they good off Amazon?
