Abstract EN
The sound radiation from elastically restrained plates covered by a decoupling layer is studied using the Spectrogeometric Method (SGM), which is a meshless and parametric modeling technique.
By adopting the Rayleigh-Ritz procedure and the Rayleigh integral, a vibroacoustic coupling system is established.
This model studies the situation when the plate is immersed in heavy fluid, such as water, in which the strong coupling between the structure and sound field should be fully considered.
The influence of the boundary conditions on the radiated sound power and sound reduction provided by the decoupling layer based on the locally reacting model is studied.
The nonuniform distributed decoupling layer is also studied to analyze the sound reduction effect.
The sound intensity on the outer surface of the decoupling layer is investigated and tends to be uniform along the plate scale with increasing thickness of the decoupling layer.
