Abstract
This paper deals with the analysis of reflected sound field from an elastic plane plate by using Finite and Boundary Element Methods (FEM/BEM). In order to solve the vibro-acoustic problem with modest computational resources, an iterative approach using FEM for solving the plate vibration and BEM for solving acoustic field.
The effect of the acoustic load on the plate vibration, the change in the reflected sound field due to the plate vibration, and the impact of the parameters of the elastic plate on the solutions are investigated by using the proposed method. The results show that the elasticity of the plate can have an effect as much as several dBs on the reflected sound field even at frequencies which are neither resonance or anti-resonance frequencies.
