Laryngeal Dynamics Laboratory

Laryngeal Dynamics Laboratory

Under the direction of Dr. Berry, the Laryngeal Dynamics Laboratory utilizes excised larynx and physical and computational models of vocal fold vibration to systematically study the basic processes of phonation. A better understanding of the mechanisms of irregular vocal fold vibration, especially in terms of a simple, low-dimensional dynamical system, facilitates the development of improved treatment options for patients with voice disorders.

This laboratory is known for its study of the medial surface dynamics of the vocal folds using stereoscopic, high-speed imaging. Drs. Zhang and Neubauer are using high-speed, stereoscopic particle imaging velocimetry (PIV) to study the complex air patterns that emanate from the glottis during both regular and irregular phonation. The glottal airflow measurements performed in this laboratory are currently clarifying and challenging basic theories of voice production.
