Visualizing diffraction of a loudspeaker enclosure

With the image-source method the room acoustics can be visualized by plotting image sources around the listener, which yields an intuitive illustration of acoustics. Lately, the image-source method has been extended to also include edge diffraction. In this paper, a visualization method for diffraction phenomenon is presented, which illustrates how diffraction behaves in different conditions. As an example, firstand second-order diffraction in loudspeaker enclosure is visualized.
