摘要： 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.
摘要翻译：用于确定声音的强度值的方法首先通过确定听众位置是否在环境椭圆区域和局部椭圆形区域之一内，环境椭圆区域和局部椭圆形区域在声音原点共享公共焦点并共享共同的中轴。当听众位置在环境椭圆区域内时，声音的强度值被设置为环境强度值。当听众位置在局部椭圆区域内时，声音的强度值被设置为局部强度值，当收听者位置不在局部椭圆区域或环境椭圆内时，声音的强度值被设置为零地区。
