Abstract
Current methods of representing energy flows in rooms have been limited to stationary pressure contour maps or intensity vectors derived from finite-element modeling (FEM) software. Despite recent advances in FEM analysis, such models are at best approximations of real-world phenomena because of the assumptions made in obtaining these results. This paper presents an energy flow visualization tool that combines the well-accepted practice of scale modeling in performance venue acoustics design and recent advances in sensor technology to provide rapid and accurate real-time maps of intensity flows derived from simultaneously-measured pressure and velocity quantities in the studied space.
