A modified 3D algorithm for road traffic noise attenuation calculations in large urban areas
H Wang, M Cai, Y Yao - Journal of environmental management, 2017 - Elsevier
The primary objective of this study is the development and application of a 3D road traffic
noise attenuation calculation algorithm. First, the traditional empirical method does not
address problems caused by non-direct occlusion by buildings and the different building
heights. In contrast, this study considers the volume ratio of the buildings and the area ratio
of the projection of buildings adjacent to the road. The influence of the ground affection is
analyzed. The insertion loss due to barriers (infinite length and finite barriers) is also …
