Numerical analyses of the sound transmission at low frequencies of a calibrated domestic wooden window

This work focuses on the numerical prediction of sound transmission wooden windows in low frequency range. In this context, finite element method is used to solve multiphysics problem. choice justified by fact that approach suitable for resolution fluid-structure interaction problems frequencies, due particular its flexibility taking into account coupling between domains and geometrical material complexities structures. To reach desired objective, experimental modal analyses main components a window, then complete one, are performed order calibrate models. Then, configuration combines free-fields both sides structure employed evaluate intrinsic acoustic response window. The results symmetric an asymmetric glazing compared ones efficiency validity developed
