这项工作的重点是人类喉部的物理模型，该模型复制了其主要组成部分和功能。该原型再现了多层声带和外展/内收运动。特别是，声带原型由软材料制成，其机械性能在粘弹性方面与天然组织相似。使用计算模型来研究声带和气流之间的流体结构相互作用。该工具使我们能够对理论结果和实验结果进行比较。测量是在一个实验平台上使用该原型进行的，该平台包括受控气流、压力传感器和用于测量声带振动的高速摄像机。数据包括起始压力时的振荡频率和声门宽度。结果表明，声带几何形状、机械特性和尺寸的组合表现出接近人类声带的振荡频率。此外，计算结果与实验结果显示出高度相关性。
This work focuses on a physical model of the human larynx that replicates its main components and functions. The prototype reproduces the multilayer vocal folds and the ab/adduction movements. In particular, the vocal folds prototype is made with soft materials whose mechanical properties have been obtained to be similar to the natural tissue in terms of viscoelasticity. A computational model was used to study fluid-structure interaction between vocal folds and the airflow. This tool allowed us to make a comparison between theoretical and experimental results. Measurements were performed with this prototype in an experimental platform comprising a controlled air flow, pressure sensors and a high-speed camera for measuring vocal fold vibrations. Data included oscillation frequency at the onset pressure and glottal width. Results show that the combination between vocal fold geometry, mechanical properties and dimensions exhibits an oscillation frequency close to that of the human vocal fold. Moreover, computational results show a high correlation with the experimental one.
