ABSTRACT:
In a system for describing directional sounds in virtual environments, a user creates a sound projection map that constitutes a two-dimensional array of sound intensities for each sound source associated with the virtual environment. At run-time, when a user selects a particular view for a scene in the environment, a hearing area corresponding to that view is calculated. The average intensity for each sound represented within the hearing area is determined from the array, to establish a level at which the sound is to be played. The sound associated with the sound source is then reproduced from a sound track at the determined level, to produce an output sound that creates a sense of place within the environment.
