Sound Transmission through Layered Media: A Simplified Method of Analysis.

Abstract

The four-pole method common to electrical circuit analysis is applied to analysis of sound transmission through layered media. This method provides a characterization of the system by means of a 2 x 2 matrix, called the four-pole matrix of the system. A general four-pole matrix is derived for a single viscoelastic layer. A sound transmission system consisting of many layers is analyzed by specializing this matrix for each layer, and multiplying the resulting matrices, giving an equivalent four-pole matrix for the system. Electrical analogs are easily computed from the terms of the four-pole matrices. (Author)
