摘要: In the present study, characteristics of acoustic field in an enclosure bounded by fractal walls are investigated using Cellular Automata (CA). CA is a discrete system which consists finite state variables arranged on uniform grid. The dynamics expressed temporary updating states cells according to local interaction rules, defined among cell and its neighbors. this paper, effect shaped boundary structure reverberation sound absorption for two dimensional wave propagation model described CA. Local rules provided construction patterns as well representation phenomena. It known numerical simulations that damping enhancement also frequency-selective absorbing behavior seen specific stage numbers.
