Abstract
The aim of this paper is to investigate the interest of a perturbation method to describe a screen effect in a room. The screen is described as an elastic plate and can vibrate. First , the sound pressure in the room is computed by using a boundary element method. Then, a perturbation method is developed taking advantage of a small parameter related to the ratio of the densities of the fluid and the plate. Numerical simulations are presented to examine the convergence of the method.
