1. The application of the HARMONOISE - IMAGINE source model on Swedish trains
Paper i proceeding, 2006

The European “HARMONOISE” project has provided a best-in-existence engineering model for the propagation of road and rail traffic noise. Its successor project “IMAGINE” is aiming at developing new methods also for industrial noise and aircraft noise, standardizing the HARMONOISE methods, and providing guidelines on how to use these methods for noise mapping. A measurement campaign has been carried out in Sweden to collect the necessary input parameters data for determining railway rolling noise emission complying with the HARMONOISE-IMAGINE source model. In this paper the HARMONOISE-IMAGINE source model for railway noise will briefly be described and the practical methods to determine the model-input parameters will be presented. For the time being only the model parameters for rolling noise have been handled, because it is the most important noise source. Traction noise will be important at low speeds and around stations and switchyards. Aerodynamic noise will become a concern when high speed trains will have been introduced in Sweden in future. The HARMONOISE-IMAGINE model has provided the guidelines for handling these noise sources.
