Description
  • A mathematical model for simulating the self-sustained vocal fold oscillations in time domain is presented. The oscillations occur when the phonation thresholds given by the critical flow velocities needed for loosing the system stability are crossed. Non-linear aerodynamic terms, fluid viscosity and contact forces for collisions of between the vocal folds are taken into account. The resulting vibratory patterns and flow values are similar to those of the real vocal folds.

  • V příspěvku je prezentován matematický model pro simulace samobuzených kmitů lidských hlasivek v časové oblasti. Samobuzené kmity nastávají po překročení tzv. hranic fonace daných kritickými rychlostmi proudění pro ztrátu stability systému. Uvažovány jsou nelineární aerodynamické členy, viskozita tekutiny a kontaktní síly při rázovém zatížení hlasivek během jejich kontaktu. Výsledné vibrační charakteristiky a parametry proudění odpovídají chování skutečných lidských hlasivek. (cs)
