The compliance of the vocal tract walls changes the phonation threshold so that a very small airflow is sufficient to vibrate the vocal folds. Comparing the same flow rates, the subglottal and radiated sound pressures are higher in the yielding-walled model. The shift of acoustic resonances towards higher frequencies due to the yielding wall corresponds to earlier experimental and numerical simulations Workplace Institute of Thermomechanics Contact Marie Kajprová, kajprova@it.cas.cz, Tel.: 266 053 154 ; Jana Lahovská, jaja@it.cas.cz, Tel.: 266 053 823 Year of Publishing 2025 Electronic address https://www.engmech.cz/improc/2024/250.pdf
