Abstract
This thesis calculates the noise emission of an metro train and tram, according to a common noise assessment method developed in the European union. To validate the choice of model parameters an acoustical camera is used to identify the position from where the noise is emitted. The accuracy of the model is found by looking at the difference between the noise emission from the calculated model, and real world measurements on trams and metro trains in Oslo. Eight measurements series of the metro train and two series of the tram were examined. Further analysis were conducted on the impact of rail corrugation on the noise emission.

The comparison between the calculated model and measurements showed us that further analysis on the model is necessary to achieve improved accuracy on the model. The thesis found room for several improvements in different aspects of the model.
