A method is proposed and the simple analytical solutions are obtained for the diffraction problems of acoustic waves on a half-plane with the impedance boundary condition on its one side and the Neumann or Dirichlet condition on the opposite side. It is shown that the properties of these solutions are essential for the optimal design of sound barriers with sound-absorbing walls.

在阻抗边界条件下，声波在半平面上的衍射。声屏障的应用

提出了一种方法，针对半平面上的声波的衍射问题，给出了简单的解析解，其一侧为阻抗边界条件，另一侧为Neumann或Dirichlet条件。结果表明，这些解决方案的性能对于具有吸音壁的声屏障的最佳设计至关重要。
