Description	The impact stress is one of the possible loading factors in phonation and it is considered as the main traumatizing mechanism in voice production and the main cause of vocal fold nodules. The contribution presents in vitro measurement of impact stress in a vocal folds replica made of silicon rubber excited by airflow with synchronous registration of the flow induced vocal fold vibrations using a high speed camera, measurement of the subglottal dynamic and mean air pressures and the radiated acoustic pressure. The airflow coming to the 1:1 scaled model of trachea was increasing from the phonation threshold up to the airflow rate 0.6 l/s and subglottal pressure 2.3 kPa, which is in the range of physiologically relevant values for a normal human voice production.
