WebPart 1: Distance Modeling and Early Reflections. Part 2: Diffraction. Part 3: Beyond Early Reflections. Sound propagates as a wave and is subject to its behaviors. One of them is diffraction, which refers to “the bending of waves around the corners of an obstacle or through an aperture” [14]. “The amount of diffraction depends on the ... WebMar 27, 2024 · In conventional ray tracing methods, diffraction calculations for wedges are typically based on the uniform theory of diffraction (UTD). However, UTD is both inaccurate and computationally expensive in the calculation of multiple diffractions. In order to mitigate these shortcomings, a Huygens' principle based method is proposed as an alternative or …
