BEM simulations for noise barriers

Noise barriers are one of the primary means in noise abatement for traffic-related noise in proximity of roads and railways. The efficiency in noise absorption and noise insulation is evaluated with different experimental methods, with the standard measurement in reverberation room and with the in-situ Adrienne method. Simulations are a helpful and cost-saving tool in predicting and planning new noise barrier solutions. In the following paper Boundary Element Method (BEM) simulations have been performed in order to assess the influence of different shapes of noise barriers in their reflecting and diffracting features. Results are presented and some practical examples are shown.
