If you have room to build a chase in the wall a 4" thickness of Aerated Autoclaved Concrete may work well. Can't help with the ceiling though. See aerconaac.com for details and specifications. Also provides fire protectio up to 4 hours.

What is the consensus on the best way to sound insulate existing PVC DWV pipes in walls and ceilings? Spray foam, pipe sound insulation and mineral wool are being investigated for a client.
