Abstract
There is a general lack of confidence in the noise barrier industry in the design and specification of effective noise barriers. There is also a need for clear guidance in the application of appropriate standards. The aim of this paper is to enable informed choices to be made using best practice in the detailed design and specification of noise barrier systems both for industrial and transport noise and to give an update of the latest developments in noise barrier design standards and technology to the benefit of the future Australasian Market.
