\nFang-Bao Tian, Siyuan Chang, Haoxiang Luo, and Bernard Rousseau<\/p>\n
Wave propagation on the vocal fold surface during phonation has been observed in clinical and physical experiments of vocal fold vibration, but it has not been well captured or studied in numerical simulations.\u00a0 Being able to reproduce the wave motion in a computer model would allow the vibration pattern of the vocal folds to be better analyzed for quantifying the vocal fold dynamics.\u00a0 In this work, we couple an immersed-boundary method and a finite-element method to compute the 3D vibration of a pair of vocal folds whose tissue is modeled as a hyperelastic material.\u00a0 With such a nonlinear material behavior, the simulation may incorporate large deformations of the tissue without the assumption for linear elasticity.\u00a0 From the 3D simulation, we observe not only wave motions in the transverse plane, i.e., along the inferior-superior and lateral directions, but also wave propagation along the longitudinal (i.e., anterior-posterior) direction in which the vocal fold model assumes a uniform cross section.\u00a0 Such longitudinal waves are also observed during human vocal fold vibration. The details of these observations and their implication on vocal fold dynamics will be discussed.<\/p>\n","protected":false},"excerpt":{"rendered":"
