Numerical study of the human phonation process by the Finite Element Method

摘要

A computational scheme has been presented to simulate the human phonation process with all relevant physical fields. Realistic self-sustained vocal fold oscillation, which where induced by airflow through the larynx have been presented. Furthermore, an Eigenfrequency analysis of different vocal fold forms showed that the first Eigenfrequency is identical to the vibration frequency in a transient setup. The generated sound showed dominant peaks in the frequency domain, which vary with the vocal fold form.
