Acoustics of the Didjeridu. 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 use ....Acoustics of the Didjeridu. 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.Read moreRead less
Beyond linear source-filter theory: how does the vocal tract affect the motion of the vocal folds? 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 ....Beyond linear source-filter theory: how does the vocal tract affect the motion of the vocal folds? 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.Read moreRead less
Understanding and overcoming technical difficulties in woodwind musical instruments. A large minority of Australians play musical instruments, and even more enjoy listening. Wind instruments predominate in school bands. This project will provide knowledge and resources that will improve teaching and playing techniques. It will also provide understanding and information useful to instrument makers, of which Australia has several. The information will be made available in both technical and non-te ....Understanding and overcoming technical difficulties in woodwind musical instruments. A large minority of Australians play musical instruments, and even more enjoy listening. Wind instruments predominate in school bands. This project will provide knowledge and resources that will improve teaching and playing techniques. It will also provide understanding and information useful to instrument makers, of which Australia has several. The information will be made available in both technical and non-technical forms via our widely used web site.
The quality of this research, its useful application to practical problems, and the rapid and easy communication to a wide and very interested subset of the public will enhance Australia's reputation for research and music.Read moreRead less
Flute properties without players, and without flutes. This project will measure how the acoustic impedance spectra of some flutes depend upon the detailed shape of the bore and the size, shape and position of the holes. It will develop a model to predict, for the benefit of instrument makers, the effect of proposed changes in the geometry of the instrument on the pitches and ease of playing of notes played on the instrument. Importantly, it will allow museum curators to determine tunings and (un ....Flute properties without players, and without flutes. This project will measure how the acoustic impedance spectra of some flutes depend upon the detailed shape of the bore and the size, shape and position of the holes. It will develop a model to predict, for the benefit of instrument makers, the effect of proposed changes in the geometry of the instrument on the pitches and ease of playing of notes played on the instrument. Importantly, it will allow museum curators to determine tunings and (uncompensated) temperaments of historic instruments that cannot readily be played.Read moreRead less
A study of vocal tract resonances in the singing voice to develop tools for teaching singing. 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 Australia's scientific reputation in an area of wide publi ....A study of vocal tract resonances in the singing voice to develop tools for teaching singing. 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 Australia's 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.Read moreRead less
