Mechanisms of sound absorption at the nanoscale. Understanding the interaction of sound with nanoscale structures will guide the creation of novel carbon nanotube materials, optimised for sound absorption, which have potential application anywhere that noise exists and needs to be attenuated. Fuel savings from reduced drag and weight in applications such as jet aircraft engines are also expected.

Summary
National laser-based non-destructive evaluation system. This project aims to establish the first Australian national facility for non-destructive evaluation, consisting of a three-dimensional scanning laser vibrometer, laser shearography, and an optical de-rotator, to enable full-field characterisation of the deformation and damage state of materials and structures. This solution is expected to perform rapid, broad-area scans, characterise dynamic response and wave propagation in human-engineere ....National laser-based non-destructive evaluation system. This project aims to establish the first Australian national facility for non-destructive evaluation, consisting of a three-dimensional scanning laser vibrometer, laser shearography, and an optical de-rotator, to enable full-field characterisation of the deformation and damage state of materials and structures. This solution is expected to perform rapid, broad-area scans, characterise dynamic response and wave propagation in human-engineered or natural structures, and diagnose rotating systems. This will enhance experimental capabilities, with uses spanning many industry sectors including aerospace, naval, automotive and medical.Read moreRead less
Understanding and predicting submarine hydrofoil noise. Australia needs to develop a more sophisticated underwater flow-induced noise research and development capability if it is to achieve its ambitious naval plans set out under the Defence White Paper. This project will develop an experimentally validated model to predict submarine noise for the purposes of submarine design, operation and procurement.
Towards an event based model of combustion generated sound. This proposal will develop new tools for predicting combustion generated sound. Since combustion noise often limits system performance, these new tools could be used to significantly reduce emissions of greenhouse gases and other pollutants from power generation and transportation.
Ultrasonic production of skim milk. Milk will be skimmed using ultrasonic waves and tiny bubbles that separate the fat droplets from whole milk, saving energy and cleaning costs. It will also be possible to precisely select different nutritional compounds from the rich resource that is whole milk, enabling future health products.
Robust signal processing theory for synthesis and analysis of spatial wavefields. This project will develop breakthrough signal processing techniques applied to wireless communication, defence and surveillance, entertainment systems, and acoustic imaging. The outcomes will produce new products. The project will also provide high quality research training for gifted postgraduate students and postdoctoral researchers.
Discovering how termites use vibrations to make foraging decisions. Termites are pests affecting one third of Australian homes. The annual cost of treatment and damage repair is over $20 billion worldwide. Yet, little is known about how termites make foraging decisions based on vibrations. This project will study the key features in vibration signals produced by termites to unlock the secrets of their foraging behaviour.
