“…Nevertheless, the weaknesses in terms of acoustic insulation of a façade remain mainly air inlets, shutter boxes, glazed parts and windows. 2,3 Unfortunately, for aesthetic reasons, large windows or even sections of glass walls are usually used in modern buildings. 4 Therefore, in order to have facades with satisfactory sound insulation, it is essential to know the acoustic performance of these elements.…”

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