The reflection and refraction of a plane acoustic wave by a thermoelastic plane layer, non-uniform in thickness, bounded by non-viscous heat-conducting liquids, generally different, is considered. The system of equations for small perturbations of the thermoelastic medium is reduced to a system of o
A sound absorber usually consists of a perforated facing backed with a porous material, and is commonly used as a sound barrier, mufler in a vehicle or any other practical acoustic application. In this paper we discuss the calculation of sound transmission loss of a perforated screen at frequencies
