EVALUATION OF NOISE ATTENUATION OF BARRIERS WITH GREENERY IN THE CZECH REPUBLIC
The article is focused on the measurements of different types of “environmental” built noise barriers (semi-vegetation, green
belt, barriers with vegetation) which were measured in the different places in the Czech Republic. In situ measuring was carried out in accordance with the standard ISO 1996. Short-term synchronous measurements were carried out in front of and behind the noise barrier and the effectiveness of noise barriers was determined. The measurement results show a slight increase in acute attenuation in anti-noise elements using vegetation. During the growing season, when greening occurs, a more pronounced acoustic attenuation compared to dormancy has been clearly demonstrated. This research was supported by the Ministry of Transport of the Czech Republic.
