The aeroacoustic mechanisms in human voice production are complex coupled processes that are still not fully understood. In this article, a hybrid numerical approach to analyzing sound generation in human voice production is presented. First, the fluid flow problem is solved using a parallel finite-volume computational fluid dynamics (CFD) solver on a fine(More)
The human phonation process is an interaction of fluid dynamics, structural mechanics and acoustics. A fully coupled simulation is expensive concerning computational time. Simplifying the model to a pure fluid simulation and prescribing the vocal fold movement reduces these costs. The movement of the vocal folds may be gained by measurement. In this paper(More)

An advanced Finite Element Method is presented which is being applied to simulate fluid flow interacting with a soft structure. Furthermore, the generated sound from fluid flow and structural mechanics is also taken into account. To get a correct model for the acoustic source terms resulting from the fluid flow Lighthill's analogy is applied, while(More)
