National Acoustic Laboratories
Day Design Pty Ltd will be conducting all commercial Acoustical Testing at the National Acoustic Laboratories.
The building industry requires manufacturers and builders to provide sound ratings for internal building partitions (walls and floors) to comply with the Building Code of Australia. In addition, windows and external facade materials are often assessed to ensure adequate reduction of noise from aircraft, trains, road traffic and industry.
Accurate acoustical information is required by architects, engineers and government and local authorities to ensure that buildings meet the requirements of technical specifications and the Building Code of Australia.
The NAL Sound Shell is a superb facility that allows the accurate measurement of:
- the noise reduction properties of building elements such as walls between apartments, windows and doors.
- the noise emission of machinery such as fans, medical equipment, air conditioners and air compressors.
- the noise reduction performance of acoustically lined ducts and duct silencers.
- the sound-absorptive properties of insulating materials.
The NAL Sound Shell comprises a large reinforced concrete building located in a quiet park environment in Chatswood. Inside the Shell a number of large rooms float on steel springs and rubber pads, which exclude all outside noise and vibration, creating a stable acoustic environment inside. It contains twin reverberation chambers, a number of anechoic chambers, a quiet air-flow tunnel and a wide range of precision acoustical instrumentation.
