Abstract : The propagation of sound from a point source situated at some height above a hard surface is studied. A solution is obtained for the intensity in the shadow zone as a function of the gradient of sound speed in a horizontally homogeneous atmosphere in which the speed of sound is linearly decreasing with altitude. The solution is obtained for the intensity as a function of frequency for both a monochromatic continuous source and a pulse (delta function) source. (Author)
