The way is simple and visual, the physical thinking of Huygens-Fresnelprinciple is incarnated fully, it helps to understand the quiddity of single slit Fraunhofer diffraction .
In this model, the noise field in sound shadow region is deduced by applying Huygens-Fresnelprinciple. It provides a new ideal for deducing the diffraction sound of complicated…
