Pressure and flow measurements in a dynamic mechanical model of the larynx and vocal tract
Pressure and flow measurements in a dynamic mechanical model of the larynx and vocal tract
A dynamic mechanical model of the vocal folds and tract has been developed. The model has moving shutters representing the vocal folds, which intersect with a uniform rectangular duct representing the sub- and supra- vocal tract. The dimensions of the model are those of a typical adult male and the shutters can be driven sinusoidally at frequencies up to 80 Hz. Duct-wall pressure measurements and velocity measurements obtained within the duct by a hotwire anemometer have been obtained. The development of the jet at the glottal exit is discussed for two different upstream boundary conditions: with and without a large compliant volume representing the lungs.

Abstract
A dynamic mechanical model of the vocal folds and tract has been developed. The model has moving shutters representing the vocal folds, which intersect with a uniform rectangular duct representing the sub- and supra- vocal tract. The dimensions of the model are those of a typical adult male and the shutters can be driven sinusoidally at frequencies up to 80 Hz. Duct-wall pressure measurements and velocity measurements obtained within the duct by a hotwire anemometer have been obtained. The development of the jet at the glottal exit is discussed for two different upstream boundary conditions: with and without a large compliant volume representing the lungs.
