Raytracing is used in commercial graphics engines most commonly for lighting effects, but it also has many uses when it comes to acoustic simulation. Adopted directly from these computer graphics programs, the formulas presented herein enable the visualization of acoustic intensity levels throughout a 3D space using Python 3 and the OpenGL library. In addition to visualization, they also provide the ability to calculate the reverberation time and critical distance of an enclosed space in relation to its size and material makeup. The described application bundles all of these components together in a Qt5 application that allows users to view …

This paper offers a review of two types of acoustic oddity caused by periodic architecture. These periodic structures of interest are brick plazas and staircases with special dimensions. When an observer stands by one of these periodic structures and produces a percussive white noise, a high-pitched sound can be heard. The frequency of the returned sound is unrelated to the initial sound, and completely determined by the architecture of the structures themselves. This phenomenon is called repetition pitch. Comparative work done at James Madison University is offered to show the relationship between brick plazas at JMU and the repetition pitch …
