| Abstract: | The sound modes in a plane fluid layer with sound-absorbing walls at different temperatures are evaluated. The eigenvalue problem is solved by means of a singular perturbation theory and the WKB method. The bending of sound, the nonexponential damping, and the roie of the wall admittance are discussed. |
