Abstract

V magistrski nalogi je obravnavano področje akustike, ki se ukvarja z okoljskim hrupom, bolj natančno s hrupom železniškega prometa. Te vrste hrup, takoj za hrupom cestnega prometa, prizadene največ ljudi. Predstavljeno je osnovno teoretično ozadje o zvoku in hrupu, aktualna zakonodaja na tem področju in načini za določevanje obremenitev s hrupom v okolju. Podrobno je predstavljen postopek ocenjevanja hrupa s pomočjo računskih metod. Dve od možnih računskih metod za izračun hrupa železniškega prometa sta tudi računski metodi RMR in CNOSSOS-EU. Uporaba metode RMR je bila do nedavnega predpisana v slovenskem pravnem redu, vendar je bila leta 2019 sprejeta Uredba o spremembah Uredbe o ocenjevanju in urejanju hrupa v okolju, ki predpisuje uporabo skupne evropske metode CNOSSOS-EU. Za obe računski metodi so predstavljene bistvene značilnosti in enačbe, ki vplivajo na ocenjevanje obremenitev s hrupom v okolju. V praktičnem delu magistrskega dela je izvedenih več primerjav med metodama, in sicer preveritev razlik v obremenitvi s hrupom na mestu ocenjevanja ob viru v odvisnosti od izbire kategorije tirnih vozil, preveritev vpliva izbire posameznih lastnosti tirnega vozila in železniškega tira na emisijo železniškega prometa in preveritev razlik v obremenitvi s hrupom med računskima metodama na območju Občine Krško. Namen primerjav je bilo ugotoviti, kakšne razlike v obremenitvi s hrupom je pričakovati pri uporabi nove računske metode CNOSSOS-EU napram prejšnji metodi RMR v praksi in kaj so razlogi za odstopanja.

Secondary title: ǂThe ǂ comparison of methods for calculating railway noise CNOSSOS-EU in RMR
Secondary abstract: The master thesis address the field of acoustics, which deals with environmental noise, more precisely with the noise of rail transport. This kind of noise, just behind the noise of road transport, affects most people. The basic theoretical background on sound and noise, current legislation in this area and methods for determining noise pollution in the environment are presented. The noise assessment process is presented in detail using computational methods. Two possible computational methods for calculating railway noise are the calculation methods RMR and CNOSSOS-EU. The use of the RMR method was until recently prescribed in the Slovenian legal order, but in 2019 Uredba o spremembah Uredbe o ocenjevanju in urejanju hrupa v okolju, which provides for the use of the common European method CNOSSOS-EU, was adopted. For both calculation methods, the essential characteristics and equations that influence the assessment of noise pollution in the environment are presented. In the practical part of the master's the following work, several comparisons were made between the two methods, namely checking the differences in noise pollution at the point of assessment at the source depending on the choice of rolling stock category, checking the impact of the selection of individual characteristics of the rolling stock and the rail track on the emission of rail traffic and checking the noise pollution differences between the calculation methods in the municipality of Krško. The purpose of the comparisons was to identify the differences in noise pollution expected when applying the new Calculation Method CNOSSOS-EU to the previous RMR method in practice and what are the reasons for the deviations.
