Diffraction of Acoustic Waves on a Half-Plane in the Case of Impedance Boundary Conditions. Applications to Sound Barriers

摘要

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.
