Abstract

Urban elements like lanes, junctions and obstacles have sound attenuation or enhancement capabilities, which effect propagation of acoustic transients in urban premises. This phenomenon is investigated and analyzed here by using BEM transients theory and formulation. The analysis simulates in time steps the changes in a sound field caused by short acoustic signals, and influenced by the configuration and boundary conditions of the domain of the investigated urban element. The analysis leads to practical conclusions concerning acoustic design and illustrates ways against the acoustic impact in residential areas. Special phenomena that are indicated in the paper are explained by solved examples. Here, in addition to Rosenhouse
