This study, presented in this paper, analyzes the primary noise in Brazilian railroads, especially in freight transport, the damage caused to the population along the railway line and proposes mitigation alternatives. The types of noise due to the passage of trains are insufficient to cause structural damage to the permanent way, but cause great inconvenience to wayside neighborhoods (residents, workers and passers-by neighborhoods located in the vicinity of the railroad), the environment, users (in if passenger transport) and the operators themselves of the composition. Brazilian standards of acoustic comfort, NBR 10151 and NBR 10152, limit noise levels in urban areas for outdoor and indoor, adopting the evaluation criteria levels in decibels (dB), but are not enough to measure the damage caused by noise of railways and neither are specific to railways. Therefore, Brazilian railways are based on the European standard, such as those developed by the International Union of Railways (UIC). Thus, this paper considers standards and the present mitigating alternatives, to improve the quality of life of neighboring communities, from the human and environmental point of view. Thus, it reinforces the need for specific Brazilian standards development on the subject.
