Influence of Meteorological Conditions on Effectiveness of Acoustic Screens – Measurements and Computations

The paper presents the results of simulation and field studies of the effectiveness of road
acoustic screens. In the simulation studies the influence of the declared weather conditions
on the predicted acoustic screen effectiveness determined for different field conditions by
different methods is analyzed. A comparative analysis of the results of screen effectiveness
computations and measurements for three real systems of acoustic screens located by national
roads in urbanized areas for different times of day is made.
