The Creation of Realistic Sound in Virtual Environment

Sound environment is the important component of the whole virtual environment. The creation of realistic sound is one of the key technoques in virtual environment simulation. Users can enhance their perception of vision channel by using aural channel. Both fidelity and immersion of virtual environment can be affected by the effect of aural perception. This paper discusses spatial aural perception model, and two models of aural perception are introduced, such as physiology cognitive model and psychology cognitive model. Based on the discussion of mathematics model created by realistic sound, this paper shows several methods to build realistic sound under Windows environment.
