Purpose: Paper presents the results of the simulation of acoustic wave propagation in quasi one-dimensional multi-layered structure. The purpose was to examine the influence of the thickness of two materials forming the transmission system, depending on the acoustic wave source frequency. Design/methodology/approach: To perform simulation, the FDTD (finite difference time domain) algorithm was used. An acoustic wave propagated through the system consisting of ten alternating layers of equal thickness, surrounded on both sides by air. On the edges of the simulation space Neumann boundary conditions were provided. Findings: Changing the layer thickness affects the position of the SPL minima and causes narrowing of the area of the total acoustic pressure curves. Research limitations/implications: The influence of changes in the thickness of the layers forming the quasi one-dimensional multilayer system on transmission was investigated. In order to better know the transmission characteristics of the system consisting of two different materials, the effect of changing the physical size of heterogeneous layers should be examined. It would be also important to compare the simulation results with those obtained experimentally. Practical implications: Simulation of quasi one-dimensional multi-layer systems allows to design new materials adapted to the requirements of specific applications without the need to carry experiment. Multilayer systems can be operated in a variety of applications, primarily as a filter with adjustable band gap frequency intermittently, and also as a material for absorbing incident acoustic waves. Originality/value: The available literature contains a limited information on the propagation of acoustic waves in quasi one-dimensional multi-layer systems. This paper responds to the demand caused by the lack of available articles in this topic and enables view the findings of research for one of the simpler periodic structures.
