The excess attenuation by a barrier parallel to an incoherent line source is shown to be calculable from the excess attenuation of sound emanating from a few points on the line source. Engineering extimates for the required length of an efficient barrier parrallel to a line source yield an aspect angle for the barrier equal to 95% of the aspect angle of the line source. The sound transmission through a barrier is found to be negligible for a typical automomotive traffic noise spectrum if the mass per unit area of the barrier exceeds 4lb/ft2.
