AB  - Traditional image-source method for room acoustic modeling neglects both diffraction and diffusion. In this study the image-source method is evolved to also include edge diffraction as diffractive image sources. Methods to find diffracting edges from a geometric model of a room, and to visualize diffracted image sources are presented. Issues to limit computational complexity and memory usage in image-source method are reviewed and implemented. Diffractive image sources are visualized for two test cases, and impulse responses are calculated and compared with measured ones.
