Modelling of airflow in human vocal tract generated by oscillating vocal folds
Original language description
The contribution describes a complex physical model of the voice production that consist of simplified 1:1 scaled models of the trachea, the self-oscillating vocal folds and the vocal tract with acoustical spaces that correspond to the vowel /a:/. The measurement set-up enabled to use the PIV method for visualization of the airflow and to perform measurements of dynamic subglottal pressure, radiated acoustic pressure and vocal fold vibration. Finite element method (FEM) was used for numerical simulationof the airflow with prescribed periodic oscillations of the vocal folds.
