Acoustic Considerations

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.

Loading component...

Class 2 to 9 Buildings

All other building classes including multi-residential and commercial buildings are covered in the BCA Volume 1 which in part requires:

Systems must safeguard occupants from illness or loss of amenity as a result of undue sound being transmitted between adjoining dwellings
Separating systems must resist undue sound transmission between dwellings
Systems must resist airborne weighted sound Rw or airborne weighted sound with spectrum adaptation Rw+Ctr
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

The Gyprock range of plasterboard with enhanced acoustic properties for use in homes includes Soundchek™ and Gyprock HD which can reduce sound transfer between rooms and the storeys of a home. Combined with acoustic insulation they are ideal to create quiet spaces around bedrooms, studies and home theatres.

Gyprock Perforated Plasterboard can be used to reduce reverberation and echo in spaces such as rumpus rooms and home theatres.

For multi-residential and commercial buildings Soundchek™, Fyrchek™, Fyrchek™ MR, EC08™ Complete and EC08™ Extreme all offer enhanced acoustic absorption and can be used in walls and ceilings to reduce sound transfer between offices, rooms in apartments, classrooms and other commercial applications. Controlling reverberation is also important in commercial buildings to improve occupant comfort. Gyprock’s Perforated Plasterboard range offers a range of high performance and attractive options suitable for foyers, theatres, libraries and gymnasiums.
