Acoustics of the Didjeridu

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.
