Sound propagation around rigid barriers laterally confined by tall buildings

摘要: Abstract This paper focuses on the propagation of sound waves in presence acoustic barriers placed close to very tall buildings. The boundary element method (BEM) is used model barrier, while buildings taken into account by using image source method. Different geometries are analyzed, representing cases a single building, two forming corner and three defining laterally confined space. barrier assumed be non-absorbing, all ground modeled as infinite rigid plane surfaces. Calculations performed frequency domain time signals then obtained means Inverse Fourier Transforms. pressure loss provided computed, illustrating importance lateral confinements.
