Název v původním jazyce
Airflow visualization in a model of human glottis near the self-oscillating vocal folds model
Popis výsledku v původním jazyce
The contribution describes a complex physical models of the voice production that consist of simplified 1:1 scaled models of the trachea, the self-oscillating vocal folds tract with acoustical spaces that correspond to the vowels /a:/, /u:/ and /i:/. Thetime-resolved PIV (Particle Image Velocimetry) method was used for visualization of the airflow simultaneously with measurements of subglottal pressure radiated acoustic pressure and vocal fold vibrations. Large vortices with dimensions comparable withthe channel cross-section were identified above the epilaryngeal part of the vocal tract model. The basic features of the coherent structures identified in the laryngeal cavity models in the interval of the measured airflow rates were qualitatively similar for all three vowels investigated.
