Resolving the mechanics of turbulent noise production. This project aims to dramatically develop our capacity to quieten modern transport, energy and defence technologies through a better understanding of how fluid turbulence creates sound. The outcome of the project will be a quieter modern environment leading to improved public health, an improved environment and a more secure nation.
INTEGRATED PASSIVE AND ACTIVE CONTROL OF HUMMING NOISE FROM KCGM’S HAUL TRUCKS. This project aims to resolve an environmental noise issue caused by the humming noise of Kalgoorlie Consolidated Gold Mines 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-perforate ....INTEGRATED PASSIVE AND ACTIVE CONTROL OF HUMMING NOISE FROM KCGM’S HAUL TRUCKS. This project aims to resolve an environmental noise issue caused by the humming noise of Kalgoorlie Consolidated Gold Mines 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.Read moreRead less
A sentinel network for vibration-based termite control. Termite damage is costly and eradication via chemicals is hazardous to environment and health. As termites use vibrations to make foraging decisions and eavesdrop on competitors/predators, it is feasible but not attempted hitherto to detect and control termites using vibrations. A smart sentinel network will be developed to enable timber infrastructure to be continuously monitored for termites and for termites to be repelled using specific ....A sentinel network for vibration-based termite control. Termite damage is costly and eradication via chemicals is hazardous to environment and health. As termites use vibrations to make foraging decisions and eavesdrop on competitors/predators, it is feasible but not attempted hitherto to detect and control termites using vibrations. A smart sentinel network will be developed to enable timber infrastructure to be continuously monitored for termites and for termites to be repelled using specific vibration signals and manipulated structures, with minimal environmental and health impacts. For this network to be efficient and effective, an improved understanding on how vibrations influence termite sociality will be obtained by studying habituation and signal adaptation on collective behaviour.Read moreRead less
Discovering how termites use vibrations to thrive in a predators' world. Our recent research revealed termites use vibrations to avoid predators/competitors for survival. However, the enabling mechanisms of this amazing ability remain unknown. The project aims at unlocking the secrets of these mechanisms by relating the mechanical properties of termite, legs, antennae and sensing organs (measured with advanced micro measurement techniques) to vibration signatures of ants and termites (extracted ....Discovering how termites use vibrations to thrive in a predators' world. Our recent research revealed termites use vibrations to avoid predators/competitors for survival. However, the enabling mechanisms of this amazing ability remain unknown. The project aims at unlocking the secrets of these mechanisms by relating the mechanical properties of termite, legs, antennae and sensing organs (measured with advanced micro measurement techniques) to vibration signatures of ants and termites (extracted using innovative signal processing techniques and nonlinear dynamics). We will develop novel bio-dynamics models that incorporate machine learning. We will test the models’ ability to manipulate termites foraging behaviour, with the ultimate objective of developing chemical-free, vibration-based pest control devices. Read moreRead less
