What is a Jet Blast Barrier or Deflector?
Airline operators face a perpetual quandary. They need to maintain a safe distance from buildings and homes but also need to be close enough to serve them. Airfields far from people make no sense, especially commercially, but operating as close to customers as possible is a delicate balancing act. The jets of a typical large aircraft at just 40% power generate...

Reverberation Time
Work spaces, rooms or general commercial building designs can quickly be perceived as having poor quality acoustic environments if resonances and reverberations occur in them. Meeting rooms and performance spaces can suffer greatly from poor speech intelligibility levels through reflected sound, while reverberation in a factory can create a potential health hazard for workers. Reverberation is the measure of time that an...

How Does a Duct Silencer Work?
We have all experienced the duct noise dilemma - do you switch off the air-con and swelter or turn it up and be deafened all night? Ducts can be noisy, but it can be much more than irritating. Duct noise in larger unattenuated systems can impact employee welfare, potentially damaging hearing. Planning applications can be turned down due to incorrect system...

Forgetting to pay attention to sound is a recipe for commercial disaster. In different types of buildings we want to minimise or maximise different types of sound. Concert halls...

Applications of Anechoic and Hemi Anechoic Chambers
Our society is far more environmentally aware than it was a generation or two back. While that is largely a good thing, it does present industry with a lot of problems. In most areas of Australia, development and expansion plans are now subjected to ever more rigorous noise-control assessments. The success of many proposals depends on being able to provide both...

Five years of growth ahead for the noise control market
Noise is an inevitable by-product of human activity, but when it reaches levels harmful to human or animal life it is internationally recognised as pollution. Airports and mining companies often face stiff resistance because of the noise pollution they might cause to residential areas. Sometimes the problem can be solved by locating facilities away from residential areas, but the harm done...

What Makes a High Performance Acoustic Doorset?
Product Range There are a lot of technical considerations in the design, manufacture and installation of high performance acoustic doorsets with the acoustic range of Rw50dB to Rw63dB. This begins with material selection for doorset fabrication, both internally and externally, relative to the performance target. IAC Acoustics designs and manufactures steel acoustic doorset assemblies of various constructions. To achieve the high...

Acoustic Enclosures & Barriers for Industrial Equipment
Introduction Australia has many blessings and one is space. Thanks to this space, noise-producing industries such as mining and manufacturing rarely contend with the same levels of protest and planning objections they would face in more densely populated parts of the world, such as Europe. Most controversies here revolve around highways and traffic schemes rather than mining, industrial or service industries. ...

Acoustic Barriers for Data Centres
Australia’s dependency on data has long been on an upward curve. Thanks to driverless cars, 5G, the IoT, the Cloud, IP telephony and now the boom in e-commerce and remote working driven by COVID-19 restrictions, our data centre industry is about to enjoy another dramatic expansion. We already have some of the largest data centres in the world and there are major...
