Noise-Level Reductions of Barriers

Doc Type: Journal Article

Abstract: The paper discusses the sound-level reductions of barriers such as solid walls and fences interposed between the source of noise and the point of observation. The formulas for the calculations are obtained from the optical case in which light is directed against a knife-edge and the light intensity is measured in the shadow (penumbra). The article contains curves showing the sound-level reduction as a function of frequency and wall height for constant distance from source to wall and from wall to observer, as well as curves showing level reduction at 100 cycles as a function of wall height and distance between noise source and wall, while the observation distance is kept constant.
