摘要：
The acoustics of a room can be visualized by plotting image sources at the positions where they occur. Recently, the image-source method has been extended to include edge diffraction. A visualization technique for image source method including diffraction is presented. As examples, first-order diffraction in a stage-house, and second-order diffraction around a loudspeaker enclosure are visualized. (C) 2003 Acoustical Society of America.
