161. Didjeridu Acoustics Australian acoustics research on the didjeridu. Sound samples, spectrogram, and description of physics of didjeridu sound production. http://www.phys.unsw.edu.au/~jw/didjeridu.html

Didjeridu acoustics This page gives a brief introduction to the acoustics of the didjeridu (sometimes spelt didgeridoo, and known as yidaki or yiraki in the language of the Yolngu, one of the peoples of Northern Australia, where the instrument originated). The didjeridu/yidaki is a remarkable instrument because of the wide variety of timbres that it produces. Further, it is of more general interest because it is the most evident example of the interaction between a wind instrument and the vocal tract of the player. These interactions are important to good playing of any wind instrument, but to the didjeridu they are central, so this page concentrates on discussion them. We also use this page to report the results of a research project, so some preliminary scientific papers are linked below. The project involves five researchers from three institutions: Alex Tarnopolsky Neville Fletcher Lloyd Hollenberg John Smith [1] and Joe Wolfe The University of New South Wales The Australian National University and [3] The University of Melbourne Lloyd Hollenberg (left), physicist and didjeridu player, managing to play the didjeridu while having the acoustic properties of his vocal tract measured. In the sound clip below, Lloyd demonstrates several didjeridu effects produced by changes in the shape of the vocal tract configuration (moving tongue and jaw) and by vocalisations (vocal fold vibration) on top of a drone with a fundamental at 71 Hz (~C#2). Ben Lange (right), is a student and didjeridu player who is also working on this project.
