Abstract

This paper concerns a combined use of BEM and cellular automata to some shape optimization in the acoustic fields. Attempt is made to find novel optimal shapes of the sound-insulating wall for reduction of noise from auto-highways. The optimization procedure is briefly explained, while emphasis is placed on demonstrating versatility of the present optimization procedure and also applicability to some topological shape optimization of the sound-insulating wall under several important situations. 1 Introduction This paper presents a combined use of BEM and cellular automata [1] [2] [3] [4] to some shape optimization in the acoustic fields. Cellular automata have been widely applied to various pr
