The propagation of acoustic wave in viscoelastic media is of extremely important in seismic exploration, seismology and so on. This paper propose a novel difference scheme for acoustic wave equation in viscoelastic media simulation, named Optimal approximate analytic discretization method (ONADM). This is a new method which can suppress numerical dispersion effectively in larger space step in recent years. The purpose of this paper is to study the propagation of acoustic wave in viscoelastic media by using ONADM method. Finally, The numerical results demonstrate that the ONAD method for acoustic wave equation in viscoelastic media has obvious advantages.
