Abstract

Sound enhances the sense of realism in the virtual world, gives additional information about the environment, for example engine speed in flight simulators. By means of sonification the information is presented in the form of an abstract sound. Unlike vision, it is not limited to the direction of view, but is present regardless of head orientation. It is also not possible to temporarily disable your hearing the way it is possible to temporarily disable vision by closing your eyes. Temporal and spatial characteristics of sound differ from those of visual perception. Although what we see exists in space and time, vision stresses the spatial component of the environment. In contrast, hearing stresses the temporal component of the environment. In the following sections, the process of creating a virtual acoustic environment will be shortly presented with basic acoustic principles, human audio perception and recording techniques.
