Abstract

A computer simulation for two-dimensional vibration of the vocal folds is presented. Free and forced oscillations are studied by imposing an impulse and time varying surface force. The solution is obtained by a semi-discrete numerical method. A finite element technique is used for the space-dependent solution and a Crank-Nicholson finite difference method is used for time integration. Horizontal and vertical displacements as a function of time, as well as x-y trajectories, are calculated for some points at the tip of fold. In addition, the response of the system due to a sinusoidally varying force was obtained and compared with experimental results of an excised larynx of similar loading. [Work supported by NINCDS.]
