Abstract
Diplomová práce posuzuje vliv zeleně na šíření hluku v okolí železničních staveb na základě rozdílu naměřených hodnot ve stejné vzdálenosti od železniční trati s účinkem a bez účinku vegetace. Měření probíhalo na třech zvolených lokalitách v několika měřicích kampaních během roku. V teoretické části práce jsou popsány mechanismy útlumu hluku vlivem vegetace, dále jsou zde uvedeny studie zabývající se využitím vegetace v protihlukových opatřeních.
The diploma thesis assesses the effect of greenery on noise propagation in the vicinity of railway constructions based on the difference of measured values at the same distance from the railway line with and without the effect of vegetation. The measurement took place at three selected locations in several measurement campaigns during the year. In the theoretical part of the thesis, the mechanisms of noise attenuation due to the influence of vegetation are described, and studies dealing with the use of vegetation in anti-noise measures are also described here.
