Despite its advantages for sustainable development, railways have great potential of noise generation. This is the main source of annoyance for railroads’ neighboring communities. Among the many types of noise that exist on a railway system, the impact noise generated at rail joints is one that stands out. To propose mitigation measures in order to solve this problem, it is necessary to understand how this noise is generated and by which parameters it is influenced. To that end, analytical models have been developed over the years. They are useful tools to verify which factors are more important to noise emission, and also can be used to predict the sound pressure level (SPL) generated and test possible solutions. This paper aims to validate an analytical model for impact noise which was originally designed for urban railways, used for passenger transportation. In this work, the validation is made using SPL measurements made at a Brazilian freight railway. The model is implemented on a software used for numerical computations and takes into account the vehicle and track characteristics, the train speed and a reference SPL. The predicted values are compared with noise levels measured at the railroad for three different joints, during railway regular operation. Besides the limitations that performing measurements during regular traffic brought to the study, the results showed good agreement with previous works.
