Macroscopic modeling of urban traffic noise influence of absorption and vehicle flow distribution
Journal article, 2005

Prediction of noise levels at shielded positions in urban areas is more difficult than on exposed positions. At shielded positions, the predictions method must include multiple reflections, and many sources must be taken into account. Using numerical methods that solve the wave equation is possible, but very computationally heavy. Here two methods have been used, a very simplified ray model and a statistical model. The results show that concentrating the traffic and introducing absorption onto building façades will give lower levels at shielded positions. © 2004 Elsevier Ltd. All rights reserved.
