Abstract

In the second volume of his Theory of Sound, Lord Rayleigh presents a method for determining mathematically the intensity of sound at very great distances from a rigid sphere, the source of sound being confined to a small area on its surface. Prof. G.W. Stewart has extended the work of Rayleigh and has calculated the relative sound intensities for sets of points lying on circles concentric with the sphere, the planes of these circles also passing through the source of sound. The points on any one circle were 15 degrees apart and the diameters of the four circles used were respectively 2, 3, 4, and 5 times the diameter of the sphere.
