Sound is very important element to enhance and reinforce reality and immersion of users in virtual reality and computer animation. Recently, significant researches about sound modeling are presented in computer graphics community. In this article, main subjects are explained and major researches are reviewed based on the sound papers presented in computer graphics community. Specially, several papers about following two subjects are reviewed in this paper: 1) synthesing sound using physically-based laws and generating sound synchronized with graphics. 2) spatializing sound and modeling sonic environment. Many research about sound modeling have been focused on more efficient modeling of real physical law and generate realistic sound with limited resources. Based on this concept, various papers are introduced and the relationship between researches about sound and graphics is discussed.
