Abstract
In the present study, acoustic wave propagation is simulated using Cellular Automata(CA) method. CA method has been attracted wide interest for modeling many physical processes which are described generally by partial differential equations, such as diffusion and wave propagation. CA is a discrete system which consists of finite state variables, arranged on a uniform grid (cell). CA dynamics is described by a local interaction rule, which is used for computation of new state of each cells from the present state at every time step. We report simulation results of wave propagation model using CA. Acoustic pipe was introduced as one dimentional model, and its pressure distribution was calculated. Furthermore, two dimentional wave propagation was simulated, where the acoustic field was driven by a point source. CA approach for such modeling is discussed, comparing with analytical solutions.
