The assessment of room acoustics commonly includes the calculation of relevant metrics by standard empirical equations or computational ray-tracing. These methods are not always sufficient for unusual shaped rooms, and can be supplemented with visualization and auralization techniques that improve our understanding of the behavior of sound in these spaces. Utilizing two- and three-dimensional room models with proprietary developed software, visualization of 360-deg particle emissions from a point source can provide useful information about sound propagation, spatial characteristics, and interactions with room boundaries. Following an iterative visualization process, design verification can be established using auralization techniques in a controlled listening environment. Such techniques facilitate better understanding of the acoustic phenomenon within the room and can help to refine acoustic solutions for room shapes or more efficient use of room surfaces for sound-absorbing finishes. Results from recent project studies show this approach to be useful to enhance communication with the architect and provides the acoustician with another useful analysis tool.
