ABSTRACT:
A method for determining the intensity value of a sound begins by determining if a listener location is within one of an ambient ellipse region and a localized ellipse region, the ambient ellipse region and the localized ellipse region sharing a common focus at an origin of the sound and sharing a common medial axis. The intensity value of the sound is set to an ambient intensity value when the listener location is within the ambient ellipse region. The intensity value of the sound is set to a localized intensity value when the listener location is within the localized ellipse region, and the intensity value of the sound is set to zero when the listener location is not within the localized ellipse region or the ambient ellipse region.
