Abstract: The contribution deals with the 2D vibro-acoustic model inspired by human phonation. Its aim is to demonstrate the in uence of vocal fold compliance on acoustic resonant frequencies. Vibro-acoustic coupling is highlighted under speci c conditions, particularly when elastic and acoustic frequencies coincide, as seen in phonation into tubes or straws of suitable lengths used in voice therapy. Here, vocal folds vibrations are modelled using linear elasticity theory and acoustics is described by wave equation. Both coupled subproblems are formulated in the frequency domain and numerically approximated by the nite element method. In the end the numerical results of the obtained resonant frequencies and their analysis are presented.
