Sumario: | This paper investigates threshold conditions of the vocal fold oscillation in the presence of a natural frequency asymmetry. Theoretical expressions for the subglottal threshold pressure and frequency are derived from a simple dynamical model of the vocal folds, and compared to data measured from a mechanical replica of the larynx under both symmetrical and asymmetrical configurations. The results demonstrate good agreement between theory and experiments, and show that the oscillation threshold is sensitive to the asymmetry with distinct behaviors between regions of low vs. high asymmetry. |
