Eliminating Noise and Vibration in Building Elements

Occupied areas in a building can be affected by noise generated in adjacent areas, whether external or internal to the building. Noise levels can be significantly reduced by the isolation of ceilings and walls between these areas. It is recommended that a specialist acoustic consultant verify the specifications for any particular application in accordance to Section F5 within The Building Code of Australia.

Ceiling Isolation

Occupied areas in a building can be affected by noise generated in the level immediately above. Noise levels can be significantly reduced by the provision of an isolated ceiling in the occupied area. The combined use of a heavy isolated ceiling and an isolated floor on the level above achieves the highest possible total attenuation.

Architectural Ceilings
Decorative lightweight architectural ceilings offer some airborne sound reduction. However, significant reductions can be achieved by increasing the mass of the ceiling using two or more layers of plasterboard in a continuous cover, and flexibly supporting the grid with isolators which statically deflect under the weight of the ceiling. 

Barrier Ceilings

Barrier Ceilings are mainly used in commercial buildings where plant rooms sit above an occupied area. A much higher degree of airborne sound reduction needs to be achieved, often requiring installation of a much heavier barrier ceiling with a decorative architectural ceiling suspended from it below.

WALL ISOLATION

Occupied areas in a building can be affected by noise generated in adjacent areas, whether external or internal to the building. Noise levels can be significantly reduced by the isolation of the walls between these areas. 

Wall isolation for airborne sound transmission reduction may need to be considered if occupied areas are adjacent to air conditioning plant or auxiliary generators, public areas, car parks or similar and for common walls between sensitive areas, as in hospitals, studios and cinemas. 

Wall isolation for impact noise reduction may need to be considered for common walls separating apartments and adjacent to public areas, as well as lift shafts sharing common walls to apartments. In addition, wall isolation may be considered within apartments between kitchens, laundries, bathrooms and bedrooms.
