In the present study, experimental analysis of this vibration was made to clarify phonation mechanism and seek better modeling of vocal folds, focusing on direct measurement of subglottal pressure and glottal velocity and simultaneous observation of vocal fold movement by means of a high-speed digital camera. The experimental results prove that subglottal pressure increases in closing phase of vocal folds and decreases in opening phase and high speed airflow just above glottis results in closing of vocal folds.

本研究通过对声门下压和声门速度的直接测量以及利用高速数码相机同步观察声带运动，对这种振动进行实验分析，以阐明发声机制，并寻求更好的声带模型。实验结果表明，声门下压在声带关闭期升高，在声带开放期降低，声门上方高速气流导致声带关闭。
