Summary/National Benefit The flow velocity within a nearly cylindrical vessel is often measured using an external ultrasound transducer via the Doppler principle. Thick vessel walls may present acoustically mismatched structures. This project aims to determine how such walls redistribute the energy in an interrogating ultrasound beam, and how this in turn affects the measurement of flow velocities. This is a fundamental issue, especially important in vascular disease where blood flow and blood vessels are affected by wall irregularities and lesions. The new knowledge generated by this project will have practical importance and, by identifying achievable outcomes, potentially major cost savings, in medical ultrasound.

Summary/National Benefit We shall undertake a comprehensive experimental and theoretical study of the acoustics of the didjeridu-lips-vocal tract system. There is very little published technical literature on the dynamic acoustics of this important and uniquely Australian instrument, whose operation is surprisingly complex. A combination of stroboscopic measurements of lip motion, acoustic and vocal tract impedance measurements, MRI imaging of the vocal tract and computer modeling will be used to synthesize all components of the acoustic system into one quantitative model. The expected outcome will be an understanding of this instrument of unparalleled detail.

Summary/National Benefit Roads cover a significant and increasing proportion of the Australian landscape, but their ecological impact is poorly understood. Traffic noise from busy roads can disturb animals over long distances, and may interfere with acoustic communication. In addition, ground vibration caused by passing traffic may disturb sensitive terrestrial animals. This project aims to assess the impact of traffic noise and vibration on communities of birds and frogs. Results of this research will provide vital information on the effects of roads on vulnerable wildlife, and the potential benefits to conservation of noise mitigation measures such as construction of tunnels and sound barriers.

Summary/National Benefit Termites can affect any Australian: one third of all Australian homes are likely to be infested by termites during their lifespan, costing a damage bill of A$780 million annually. Despite this level of damage, our understanding of the underlying foraging behaviour of termites is poor. Termites, being blind, cannot use visual cues and chemical cues are insufficient to explain observed phenomena. Our preliminary work has identified vibro-acoustic signals used for information gathering and communication in foraging. The project aims to study vibro-acoustic mechanisms for communication in termite foraging behaviour. Anticipated outcomes include a significant impact on termite control.

Summary/National Benefit This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity. The challenges with lake acoustic tomography are the accuracy required in the travel time measurements over shorter distances, acoustic losses due to reflections and ensuring enough rays travel through the thermocline, the region of greatest interest in lakes. A pilot experiment in a deep lake will investigate the quality of travel time measurements computed from rays travelling through the thermocline of a strongly stratified lake. This has wide applications for the water quality management of lakes and reservoirs.

Summary/National Benefit The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level around the world, with devastating effects on the continental coasts and low-lying islands. The method of remote acoustic observations investigated in this project is a new approach to the problem of creating an efficient and cost effective system to monitor rifting and calving of the Antarctic ice shelves.

Summary/National Benefit Chronic ear infection blights the life of at least 50% of Aboriginal Australians. In a vicious cycle that extends from generation to generation, it leads to hearing loss, educational disadvantage, socio-economic disadvantage and environmental depredation, which once again leads to ear (and many other) infections. This is a unique attempt by researchers across academic disciplines to study the role of language in educational disadvantage and whether this disadvantage might be made worse for Aboriginal children by the early use of English at school. We ask whether, on purely acoustic or linguistic grounds, communicating in an Aboriginal language might offer improved educational and health outcomes for Aboriginal children in the early years.

Summary/National Benefit The voice is our oldest and most widely used musical instrument, but it is incompletely understood because of the difficulty of studying the vocal tract precisely during singing. We shall determine the main techniques used by singers to control and to adapt the acoustic resonances of their vocal tracts. This advance in understanding will enhance Australias scientific reputation in an area of wide public interest. Further, when combined with developments of our novel techniques to operate in real time, it will provide a new tool for students of singing to adjust their resonances and prevent damage to the vocal tract. We shall publish our work not only in the top scientific journals, but also on our popular, multi-award winning web site.

Summary/National Benefit We aim to create new Audio User Interfaces (AUIs) for the automatic separation and annotation of audio from complex sound scenes using acoustic vector sensor beamforming technology. Specifically, we will develop: speech AUIs for noisy, multi-talker, reverberant environments; and sound transcription AUIs for the deaf. Ultimately, users will be able to walk into a room, hold conversations and leave with a searchable, automatically-generated transcript of the audio events, tagged with metadata. The application of these technologies will create new possibilities for recording audio in the music, radio, TV industries, and future home based audio communication systems.

Summary/National Benefit The project represents cutting edge research in the field of soundfield recording, audio compression and reproduction. The introduction of explicit acoustic field theory to the field of audio compression is a substantive and innovative change that not only furthers the knowledge base in the field but also provides a framework for contributions in related fields such as auditory prosthetics and noise cancellation. The most obvious benefits will be international acclaim and the opportunity to patent, develop and ultimately export technology and systems. Outcomes from the project will benefit consumers and facilitate diverse industries within Australia ranging from health management to the consumer electronics and entertainment industry.

Summary/National Benefit The human voice lies at the very core of human culture. Yet the way in which the vocal folds (vocal cords) vibrate is only partly understood and the way in which sound waves within the vocal tract affect this vibration is almost unknown, beyond the fact that it is sometimes important. Using new and unique non-invasive techniques, we shall conduct acoustic experiments to measure properties of the vocal folds and their interaction with the sound they produce in the vocal tract. This knowledge will solve some of the remaining puzzles about the voice. Practical applications will include exercises in voice control (especially for singers and orators) and potential applications in clinical diagnosis techniques.
