“…At the non-ideal level joint, with an 11 mm horizontal gap, the SPL recorded was 92.00 dB (A), for the same train speed. Studies show that the impact noise generated at joints is 5 to 8 dB greater than regular rolling noise (Sueki et al 2017). So, the results obtained in this case well agree with the ones found in the literature.…”

The noise generated by transportation systems is one of the most important causes of noise-induced annoyance, since exposure to high level noises for long periods of time can be detrimental to health. Amongst the different types of noise that originate from railroads, the squeal noise generated at curves, the impact noise generated at rail joints and the rolling noise stand out. To propose mitigation measures to this problem, noise generation must be understood as well as by which parameters it is influenced. To that end, analytical models have been developed to predict the generated Sound Pressure Level (SPL) and to verify which factors are related to noise generation. This paper aims to validate analytical models for impact noise, squeal noise and rolling noise, which were originally designed for urban railways, used for passenger transportation. In this work, the validation is made using SPL measurements taken at a Brazilian heavy-haul railway, and a railway which carries bulk cargo in general. The models are implemented on a numerical computation software considering vehicle and track characteristics, train speed and a reference SPL. The results obtained from the models were compared with SPL measurements performed at the railroad during regular operation for the three cases (rolling, squeal and impact), which, despite the measurement limitations imposed by practical constraints during regular traffic operation, showed good agreement.

“…2. Studies suggest that the main impact noise tones have frequencies of 250 Hz to 2 kHz, approximately, close to the frequency range in which human hearing is more sensible (Sueki et al 2017).…”

“…Os impactos nas rodas e trilhos podem aumentar a vibração e o ruído gerados (THOMPSON;GAUTIER, 2006). A descontinuidade mais comum nas rodas é o achatamento, causado pelo desgaste durante as frenagens, enquanto nos trilhos pode haver descontinuidades como degraus entre trilhos ou depressões nas talas de junção (SUEKI et al, 2017).…”

Atualmente, cresce o modal ferroviário no mundo inteiro devido a várias vantagens. No Brasil, com recentes incentivos a concessões de ferrovias e com o aumento da produção de commodities é esperado o desenvolvimento do transporte ferroviário de cargas no país. Contudo, com esse crescimento, é potencializado alguns impactos ambientais, dentre eles a vibração ferroviária, que pode afetar pessoas e edificações próximas às vias férreas. Desta forma, compreender causas e efeitos da vibração ferroviária é fundamental para buscar soluções que mitiguem seus efeitos negativos. Desta forma, este artigo tem como objetivo apresentar uma revisão de literatura dos principais aspectos relacionados à geração, efeitos, descritores normatizados e ações de mitigação da vibração ferroviária associada a trens de carga. Esta breve revisão serve como ponto de partida para que novos estudos e pesquisas sejam realizadas no tema com o intuito de que este tipo de impacto ambiental não traga prejuízos ao desenvolvimento desse importante meio de transporte.

“…This was done by measuring noise and rail vibrations on an inservice line, to investigate contributions of wheel noise, rail noise and sleeper noise to total impact noise, and the effects of noise abatement measures, etc. by building physical models [7]. Some case examples have been reported of a particularly high frequency noise of 10 kHz or more being generated by passing trains in some curved sections, adversely influencing overall noise along the railway line.…”
