Numerical Analysis of Noise Barriers with Novel Caps

Popis výsledku v původním jazyce

Paper presents a comprehensive analysis of the insertion loss of noise barriers with novel caps (partially inclined barrier, T barrier, Y barrier, arrow barrier, Y barrier with edges, trident barrier and fir tree barrier). The boundary element method isused in order to model the scattered sound field and calculate the insertion loss of noise barriers with various novel caps for one-third octave frequency bands. Special emphasize is put on the partially inclined barrier which is analyzed from the perspective of orthogonal distance of the receiver and the sound source from the axis of noise barrier. Influence of the partially inclined barrier height on the resulting insertion loss is also investigated. Furthermore, different variants of the flow resistivity of upper horizontal edge of T barrier are modelled. Paper contains a graphical comparison of the insertion loss of several noise barriers with novel caps. Suitability of different noise barriers with novel caps for practical purposes
