One of the main factors involved in the laryngeal dynamic's non-linearity is the coupling between the two vocal folds. Evaluation of the different coupling elements requires various investigations. The present work evaluate the non-linearity effects in clinical situations such as unilateral laryngeal paralysis using Lyapunov's coefficients. It also demonstrate the coupling effects on excised larynx made experimentally asymmetrical, using a specially designed device to measure vibrations from each vocal fold (opto-reflectometer).
喉动力学非线性所涉及的主要因素之一是双侧声带之间的耦合。对不同耦合元件的评估需要进行各种研究。本研究使用李雅普诺夫系数评估单侧喉麻痹等临床情况下的非线性效应。它还使用专门设计的装置（光反射计）测量每个声带的振动，展示了对实验性不对称切除喉的耦合效应。
