Calculation of Sound Wave Propagation, Radiation andTransmission through Plate with Different BoundaryConditions

摘要

Sound wave propagation, radiation and transmission through plate are analysed usingintegral formulation of the solution. Investigation is based on Fourier transformation method for soundmultipole models and on equation of transverse displacement of plate which is driven by harmonicacoustic wave. Sound wave propagation is focused over impedance surface. Exact analytical solutionsare presented. The influence of the sound fields parameters and boundary conditions are investigated.Some examples show new features of vibroacoustical fields near plate surface.
