In this paper the authors propose two dimensional sound pressure propagation simulation considering diffraction and reflection generated by CA method and Image source method. Because it is necessary we consider a reflection and diffraction in the vicinity of an obstacle to observe influence when there are obstacles such as people in speaker array in sound pressure spread simulation. This paper describes control of reflection using CA method and Image source method and diffraction by CA method and comparison of an approximation theory of Kichhoff.
