Acoustic Scattering from a Rectangular Window or a Balcony in a Building Facade

摘要

In this paper we present a 2D mathematical model for the acoustic scattering from a rectangular window or balcony in a building facade. The model, inspired by a recent paper, is based on the Fourier transform and the mode matching methods. It allows to express the scattered and the transmitted field by a window (or a balcony) as series solutions which can be easily computed. Numerical applications are discussed and some examples are given.
