Abstract
Considering the great variety of railway noise prediction models, there is a problem regarding the choice of a standard in a country without its own model Thus, a real case in a very specific and well characterized context has been studied and several European models have been compared. All the necessary parameters for each model have been introduced and the variations between these models have been analyzed. In order to make a qualitative and quantitative comparison, experimental measures have been made, characterizing the simulated source of noise Besides comparing several European prediction models, the existing differences between the models implemented in both Lima and SoundPLAN simulation programs have been studied The aspects compared are the accuracy of each model, the input data required by the simulation programs and the difference of results between programs. In addition, the necessary adaptations to each model with respect to the real scene have been made to obtain the most precise results. Thus, an attempt has been made to draw up a comparative study of the small deviations and necessary adjustments when using a model created with conditions different from those of the real scene.
