Abstract
The work aimed to analyze the noise behavior in the railways in the city of Santa Maria/RS, through the development of an expression that shows the individual contribution of the variables studied. Is possible to note that field measurements and data from similar researches were used, aiming to increase reliability in the results and enabling the expansion of the use of the proposed model. As in Brazil there aren't specific standards for the study, the NBR 10151 normative and the Code of Postures of Santa Maria were used for the data collection procedure and analysis of results. Data were collected at the station GARE and level crossing RuaSete de Setembro. Among the values it was noted that all were above the limits specified by existing regulations, 72.88 dB and 83.42 dB the lowest and the highest found, respectively. The results from the studies were analyzed together with the data from Specht et al. (2012)Specht, L. P. ; Kohler, R. ; Bronzatti, G.(2012) . Ruído causado pelo transporte ferroviário em um segmento urbano: estudo do caso da cidade de Ijuí-RS. Teoria e Prática na Engenharia Civil (Online), v. 19, p. 13-23., setting up noise curves that were relevant and reliable for train speeds from 0 to 25 km/h 0 receptor distances 20m.
