The fluid flow within a human larynx plays an essential role in the fluid-structure-acoustic interaction during phonation (Kniesburges et al., 2011). This study quantifies the flow field downstream of synthetic vocal folds in the supraglottal region in order to complement already published findings (Kniesburges et al., 2013). An experimental setup for(More)
Within the human larynx, the ventricular folds serve primarily as a protecting valve during swallowing. They are located directly above the sound-generating vocal folds. During normal phonation, the ventricular folds are passive structures that are not excited to periodical oscillations. However, the impact of the ventricular folds on the phonation process(More)
The sound spectra obtained in a synthetic larynx exhibited subharmonic tones that are characteristic for diplophonia. Although the generation of subharmonics is commonly associated with asymmetrically oscillating vocal folds, the synthetic elastic vocal folds showed symmetrical oscillations. The amplitudes of the subharmonics decreased with an increasing(More)
