To ensure the building is capable of providing an appropriate acoustic environment to provide comfort for building users.

• Minimise disturbances to building occupants from noise transition between spaces.
• Enhance productivity by providing appropriate acoustic environment for the different functions of various buildings and spaces.

Noise within buildings can come from various sources, including building systems, occupants, equipment and external sources. Excessive noise can have a range of adverse effects on building users including inconvenience and annoyance, loss of concentration, decreased productivity and sleep disturbance. Therefore, the management of noise within a building is important to maximise occupant comfort, occupant efficiency and to provide privacy. As a result, building acoustics are an important consideration in the design, operation and construction of buildings. Building acoustics should allow rooms to be used as intended, without compromising sound-sensitive spaces or activities. Designing to building type specific acoustic performance standards for sound insulation, indoor ambient noise levels and reverberation times, supports acoustic comfort for building occupants.
