Propagation From a Line Source Above an Impedance Plane

The problem of acoustic propagation from an isotropic monofrequency point source in a homogeneous fluid half-space above a locally reacting plane boundary of uniform surface impedance is one of the basic theoretical problems arising from a study of outdoor sound propagation.Good recent treatments of this problem are given in 15.16.11.The related.and simpler problem, of propagation from a horizontal coherent line source above a horizontal plane of uniform surface impedance, has received relatively little attention, perhaps because of its less obvious practical
