Abstract

V magistrskem delu smo proučevali obremenjenost okolice Ceste proletarskih brigad v Mariboru s hrupom cestnega prometa. Izračune hrupa smo opravili po metodah NMPB 1996 in CNOSSOS ob uporabi realnih in modelskih vhodnih podatkov. Pozornost smo namenili postopku pridobivanja vhodnih podatkov, njihovi kakovosti in analizi rezultatov različnih metod. Za različne scenarije smo izračunali zvočno moč cestnega prometa in izdelali karte hrupa. Pridobljeni podatki o površinah raziskovalnega območja, na katerih so kazalci hrupa prekoračeni, so bili osnova za izračun števila stavb in prebivalcev, ki so obremenjenih s hrupom cestnega prometa, in predloge omilitvenih ukrepov. Rezultati so pokazali, da je metoda NMPB 1996 primernejša za uporabo, saj ima metoda CNOSSOS pomanjkljivosti v zvezi s širjenjem hrupa. Z realnimi vhodnimi podatki se bolje opiše stanje okolja kot z modelskimi, vendar je njihovo pridobivanje kompleksnejše, dolgotrajnejše in dražje, zato se njihova raba priporoča v primeru študij na manjših in gosto poseljenih območij z močno obremenjenimi cestami.

Secondary title:	Comparison of the noise calculation methods NMPB 1996 and CNOSSOS using real and model input data
Secondary abstract:	In this master's thesis, we studied the exposure to road traffic noise in the vicinity of Cesta proletarskih brigad in Maribor. Noise calculations were performed using the NMPB 1996 and CNOSSOS methods with real and model input data. We paid attention to the process of obtaining input data, their quality, and analysing the results of different methods. For different scenarios we calculated the sound power of road traffic and produced noise maps. The data obtained on the surface area of the study area where noise indicators are exceeded were the basis for the calculation of the number of buildings and residents exposed to road traffic noise and for mitigation suggestions. The results showed that the NMPB 1996 method is more suitable for use because the CNOSSOS method has disadvantages related to noise propagation. Real input data describes the state of the environment better than model data, but obtaining real data is more complex, time consuming, and more expensive, so it is recommended in studies in smaller, densely populated areas with heavily congested roads.
