Název v původním jazyce

Experimental investigation of air pressure, acoustic characteristics and vibrations of vocal folds on a complex physical model of phonation in humans.

Popis výsledku v původním jazyce

The contribution aims to provide material that can be used in development of more realistic physical as well as theoretical models of voice production. The experimental set-up, methodology and the results of measurement of airflow rate, subglottal, oraland generated acoustic air pressures are presented together with the simultaneously measured flow-induced vibrations of a vocal folds replica, made of soft silicon rubber, and recorded by a high speed camera. The data were measured during a soft? phonation just above the phonation onset, given by the phonation threshold airflow rate, and during a normal? phonation for the airflow rate of about three times higher. A model of the human vocal tract in the position for production of vowel [u:] was used andthe flow resistance was raised by phonating into a glass resonance tube either in the air or having the other end of the tube submerged under water, and by phonating into a narrow straw. The results for the pressures presented in time and
