Voice Lab Research Equipment

Kay Elemetrics Video Stroboscopy System

Stroboscopy provides a slow-motion view of the vocal folds as they vibrate. It is critical to observe the vibratory characteristics of the vocal folds in order to accurately assess phonatory function, and, in some cases, to detect and/or differentiate lesions. Stroboscopy is the only practical tool for observing vocal fold symmetry, amplitude, periodicity, completeness of vibratory closure, and the diagnostically important mucosal wave.
