Acoustic energy as radiated from effective incremental cylindrical surfaces is considered, which during the course of initial propagation are assumed to become hemisperhical and divergent. These are summed along piping runs under chosen gradient conditions representing an intensity decay along the pipe. A computer program for scanning the geometry of these incremental radiating surfaces is provided to include the effect of barriers in the line of propagation. Printout is both octave-band and “A” weighted.
