Abstract:
The effect of urban street geometry on sound pressure level distribution is
numerically studied with the finite-difference time-domain method. The Cnossos
equivalent power spectra were used to approach road traffic noise sources along
two
traffic lanes. Receivers both along the buildings’ facades and the walkways have
been analyzed. Predictions indicate that street geometry, building shape and
street
furniture can have a strong impact on sound pressure levels. The presence of
such
urban elements in streets might lead to a reduction of up to 10 dBA, building-
façade design-benefits can also be found. It can therefore be concluded that
urban
canyon design may significantly contribute to reducing noise levels for people
directly exposed to roads as well as for pedestrians. Building façade and street
design is currently unexploited and should be considered in future urban
planning.
