Prediction of noise from trams

An improved calculation model for the prediction of levels of noise from trams is presented. The model is based on current calculation models for noise from trams and the measurements of equivalent noise levels from trams carried out in Kos̆ice, Slovakia. The data were processed using correlation and regression analysis and besides already known factors (the number of tram sets passing a certain location per hour, tram speed, the type of tram rail, the tramline gradient), several new factors (wavelength of rail corrugations and rail grinding, the age of the tramcars and tramlines and the detailed composition of tram sets) have been included in the presented calculation model for the prediction of levels of noise from trams.
