This problem consists of the three physical fields: a highly complex airflow\, a vibrating elastic structure (vocal folds) and acoustics and th eir mutual interactions. The general mathematical model of FSAI problem wi ll be described and the later simplifications of it will be discussed. Si nce the main sound source of the human phonation is generated by an unstea dy flow in the complex configuration of vocal tract the aeroacoustics as a separate branch of acoustics will be introduced. The ultimate goal of the aeroacoustics is to establish a well solvable simplification of the full description provided by the Navier-Stokes equations (for compressible flui d). Due to recent advantages the computational aeroacoustics has attained also a high interest in the field of technical applications. In the end th e numerical simulations of flow-induced vibrations of vocal folds and the propagation of sound through human vocal tract based on the previously men tioned approaches will be shown.\n LOCATION:https://researchseminars.org/talk/NSCM/188/ END:VEVENT END:VCALENDAR
