A good number of buildings are located very close to road junctions in Dhaka City. Due to poor setbacks, building edges hinder visibility. Traffic noise travelling from the main road to a secondary road and vice versa diffracts at building edges creating virtual images of the noise source. This may cause confusion and lead to accidents. It is established that noise threatens human health. But it is not much explored how this unique phenomenon of sound diffraction at road junctions, as a side effect of noise pollution, may create confusion and cause accidents. From instrumental measurements and practical observations, this study identifies evidence of sound diffraction, the virtual position of noise source and its effect on erroneous perception at road junctions. This paper suggests proper setbacks of buildings, appropriate geometry of building edge and suitable acoustical properties of finish materials to eliminate diffraction of sound at road junctions of Dhaka city.
