The BCA includes requirements for acoustic performance of walls and ceilings to help ensure occupant comfort and privacy. Gyprock has developed a broad range of acoustic systems to help specifiers and builders meet the BCA requirements with confidence. A range of Gyprock's acoustic products are also suitable for use in areas where enhanced acoustic performance will improve the experience of the space.

- Floor ceiling systems must also resist impact sounds Lnw
- Where required wall systems with an impact sound rating must also be of discontinuous construction (i.e. 2 separate leaves without rigid mechanical connection except at the periphery or masonry leaves connected by resilient ties)
- Systems isolating services between sole occupancy units must resist airborne weighted sound with spectrum adaption Rw+Ctr
