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.

Didjeridu的声学。我们将对didjeridu-lips-声道系统的声学进行全面的实验和理论研究。关于这种重要而独特的澳大利亚乐器的动态声学，其操作令人惊讶地复杂，发表的技术文献很少。唇运动频闪测量、声学和声道阻抗测量、声道MRI成像和计算机建模相结合，将声学系统的所有组成部分合成为一个定量模型。预期的结果将是对这一工具空前详细的了解。
