Due to the dynamic development of railway transport, it is necessary to supervise its impact on people and the surrounding environment. Noise is the main subject of this work, as it is the main railway transport factor that causes annoyance for the environment. Regarding increased speed railways, works are currently being conducted to fi nd the dominant sources of negative acoustic eff ects. Determining the motives that cause rising of the noise sources, indexing them as well as creating an

Th e authors have reviewed publications concerning the currently-utilized methods, described a noise assessment approach, and proposed a way to conduct fi eld tests on real objects. A location was chosen, required permissions were obtained, sophisticated measuring equipment was collected, and pilot experimental tests were performed, with the results being described in this work.
