A comparison of computer modeling auralization and binaural room recordings for a multipurpose high school auditorium utilizing an orchestral shell, overhead panels, and clouds.

Abstract

The development of auralization techniques has provided a new method to demonstrate potential acoustical benefits of changes in design or the application of acoustic treatments in specific spaces. It’s useful to compare the results from the auralization process with actual binaural recordings in the physical space to discover similarities and differences. A typical high school proscenium-style, multipurpose auditorium was modeled, including an orchestral shell, overhead panels, and clouds. Auralizations were made of the auditorium at various locations in the audience area and on stage, with and without the shell and overhead panels, in place. These were compared with binaural recordings made at the same locations within the auditorium. Auralization metrics will be compared with the binaural recordings, highlighting the changes made with the shell and overhead panels in place, along with the similarities and differences between the two methods.
