- Railway noise in towns and city centres is one of the environmental problems. Defining the noise level is possible in two ways - via in situ measurement or via calculation (prediction). For the comparison of objectively measured values of sound pressure levels from railroads two methods used in the Slovak Republic were chosen - Schall 03 and the Czech prediction method. Track number 170: Zvolen-Vrútky in the town Zvolen was selected as the measurement location of noise exposure. Method Schall 03 overestimates the measurement values by approximately 1 dB and the Czech method by 4 dB. Both prediction methods, in spite of the systematic overestimating, describe the real noise situation very well; the calculated Pearson coefficient of correlation with Schall 03 method was 0.94 and with the Czech method 0.90.
