Brief description This project aims to resolve an environmental noise issue caused by the humming noise of KCGM haul trucks in the areas of Kalgoorlie, Boulder, and Williamstown. This solution utilises integrated passive and active control systems to attenuate the frequency components of humming noise from a truck’s exhaust and engine. A novel aspect of this technique is the use of passive micro-perforated structures to provide the necessary sound absorption capability and to alter the sound propagation and radiation properties of the truck exhaust and engine, and increase the effectiveness of active control.
