Abstract
This paper presents the results of a noise study in the areas surrounding a railway line and a bridge, in a large municipal agglomeration. Sound characteristics were determined in the one-third octave bands and narrow frequency bands, and bridge vibration studies were carried out. The relationships between the vibrations of some elements of the structure and the acoustic pressure in its environment were revealed by applying a coherence function. The sources of excessive noise emissions to the surrounding environment were identified, and solutions for modernizing the railway infrastructure of the region were proposed.
