Abstract
Measurements of air pressure and flow were made using an in vivo canine model of the larynx. Subglottic and supraglottic pressures at varying flow rates were taken during phonation, induced by laryngeal nerve stimulation. Results shows that, during constant vocal fold stiffness, subglottic pressure did not rise significantly with increased airflow. Increasing flow rate was associated with an increase in the open quotient as measured glottographically. Data from this experiment were compared with the theoretical two‐mass model of the larynx. Model parameters were adjusted to approximate the canine vocal folds and the in vivo experimental pressure‐flow relationships were simulated. The larynx in the in uivo canine model exhibits flow‐dependent decreasing impedance during phonation in that increasing flow rate is not accompanied by increases in subglottal and transglottal pressure.
