Acoustical diffraction modeling utilizing the Huygens-Fresnel principle

This paper describes the application of the Huygens-Fresnel principle to acoustical diffraction modeling. A theoretical formulation of the optics-based Huygens-Fresnel principle is presented followed by a discussion regarding the modifications necessary to apply the Huygens-Fresnel principle to acoustical diffraction modeling. Experimental results indicate the method is capable of modeling acoustical diffraction phenomena in a simple and efficient manner, making it attractive for interactive virtual environments.
