Imaging the inferior surface of synthetic and excised vibrating vocal folds

Quantifying the dynamic motion of the vocal folds is important for developing models of voice production as well as obtaining a general understanding of the physics involved in voicing. Previous research has focused on imaging and quantifying the dynamics of the superior surface and medial surfaces of the vocal folds using excised larynges, but very little has ever been done to image the inferior surface of the vocal folds during vibration. In this presentation a method for imaging the inferior surface using a mirror and multiple high-speed digital cameras is introduced. Results obtained using a self-oscillating silicone model are presented. Findings from the results as well as anticipated future work to apply the methodology to excised animal models will be discussed.
