The fundamental sound is created by the mutual\ninteraction of the flowing air with vibrations of vocal folds(VFs). The\narising fundamenta l sound is enriched by aeroacoustic sound sources and\npropagated through the vocal tract. In this talk\, mathematical models of a\nsimplified fluid -structure-acoustic interaction problem shall be\,\nnumerically discretize d and numerical results will be presented. In\nparticular the deformation of an elastic body representing the model of\nvocal folds will be consider ed in the interaction with the complex fluid\nflow and aeroacoustics. In p articular the attention will be paid to several\nimportant issues of such a modelling as the inclusion of the VFs contact\,\nchoice of suitable boun dary conditions\, the influence of pre-stressed vocal\nfold on the fundame ntal frequency\, etc. For the flow model the realization\nof the variation al multiscale method is discussed. The numerical\napproximation of the pro blem is presented and numerical results are shown.\n LOCATION:https://researchseminars.org/talk/NSCM/90/ END:VEVENT END:VCALENDAR
