Engineering formulas for ground effects on broad-band noise

Abstract A simple approximation of ground effect is analyzed for two cases: (1) stationary point source and (2) moving line source (train). The approximation contains three adjustable parameters that are estimated from the exact theory (case 1) and from field measurements (case 2). Finally, the results of computation are used for noise prediction.
