Matrix formulation in Acoustics: the Transfer Matrix Method

Abstract : Matrices are introduced in mathematical subjects related to vector spaces and linear Algebra, being disconnected with their applications in other fields of Science and Engineering studies. The transmission of this knowledge is done, in many occasions, in a purely theoretical manner and posing problems to students that are sometimes abstract, lacking application to real world. In this paper we present an application of matrix formalism in Acoustics: The Transfer Matrix Method. It is a simple method widely used in transmission problems. For a system composed of a waveguide and an aluminum plate, subjected to the pressure of an acoustic wave, we can establish a simple connection between the matrix formalism, the use of vectors and the physical magnitudes
