Separate and isolate wall systems from the structure to prevent airborne and structure-borne noise from transfering into and out of the space through the use of architectural acoustic materials. PAC-International by ARCACOUSTICS offers excellent solutions for achieving noise reduction in walls through the use of their acoustic isolation clips to decouple the structure. Pyrotek solves common noise and vibration problems through the use of their eco-friendly sound absorber, Reapor, and their Wavebar line of flexible noise barriers.
