"Our tests revealed that viscoelastic paneling is an equal if not better solution than. mass loading to soundproofing". Dowload this MS Word Document, it is a study by Pratt School of Engineering at Duke University. It looks at different construction techniques for soundproofing. It compares the use of mass to block sound to the use of viscoelastic damping material (QuietRock Panel QuietSolution). Interesting read, viscoelastic material proves to be slightly better than mass. If your interested in learning more about viscoelastic damping surf on over to to Audio Alloy. They have a great product called Green Glue. I will be using this product in the future.
