Discrete Simulation of Sound Propagation in the City Based on Cellular Automaton

Abstract : This paper deals with the problem of sound propagation in urban areas. It begins by investigating the propagation of sound in order to determine and extract the physical parameters that direct this propagation. The formalism of cellular automata (CA) is presented, as well as its use for the specification of physical phenomena, with discrete events, such as sound propagation. The use of cellular automata in a smart city context, to model the propagation of sound is presented. The proposed model takes into account buildings and other city obstacles. A CUDA Implementation of this model is described. This implementation is used to simulate sound propagation on shapefile cards. The proposed model makes it possible to determine the sound power in a given location and the geographic area covered by the sound wave.
