Acoustics of the Didjeridu

迪杰里杜的声学。我们将对DidJeridu-嘴唇-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方面发表的技术文献很少，其操作令人惊讶地复杂。将结合频闪测量嘴唇运动、声学和声道阻抗测量、声道MRI成像和计算机建模，将声学系统的所有组件合成到一个定量模型中。预期的结果将是对这一具有无与伦比细节的工具的理解。

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.
