A simple method is proposed for solving the problems of diffraction of plane sound waves on a half-plane with different-type boundary conditions on its surfaces (the Neumann condition on one surface and the Dirichlet condition on the opposite surface). In contrast to existing techniques, the proposed method allows one to obtain analytical solutions valid near the half-plane edge and at far distances from the edge.

硬-软半平面上平面声波的衍射

提出了一种简单的方法来解决平面声波在其平面上具有不同类型边界条件的半平面上的衍射问题（一个表面上的诺伊曼条件和相对表面上的Dirichlet条件）。与现有技术相反，所提出的方法允许人们获得在半平面边缘附近和距边缘很远的距离处有效的解析解。
