This paper exposes, and analyzes the validity of, a novel hybrid acoustic modeling system created through complementary assimilation of 3D geometric and 2D numerical modeling techniques. It is demonstrated that multiple 2D Finite Difference Time Domain schemes may be employed to simulate low-frequency sound wave propagation throughout a simplistic 3D(More)
