INTERRUPTED TRAFFIC NOISE

A one-parameter model (xi) for stop-and-go noise is developed. The phy sics of the phenomenon is based on the idea of the linear density of r adiated energy. The methodology of xi determination has been worked ou t and illustrated. The noise interaction with the surface of the groun d is considered to be the only wave phenomenon that disturbs geometric al spreading. The model makes possible the calculation of the correcti on term in the time-average sound level, L(AT), as an adjustment to th e constant speed model of traffic noise.
