• Resumen

  • Currently there is no consensus for the assessment of the human response to indoor vibrations.

    Also, the methodology used by several countries is different, as can be seen from the publication and use of different normative documents. This paper presents a proposal for the preliminary evaluation of railway projects, through the calculation of transfer functions and their corresponding validation when the line begins operating. For this purpose, an admissibility criteria, and corresponding equivalence in terms of human response to vibrations, is also presented. Additionally, this paper presents a proposal for the measurement of vibration and noise induced by the passage of rail traffic inside the buildings.
