Official deliverable for general European Road Noise Sources[11 January 2006]
The first official deliverable for Road Noise Sources called "Assessment Programme for Parameters of the "general" European vehicle fleet" is downloadable here (bottom of the page).
Work package 5 of the IMAGINE project deals with Road noise sources and has the task “to provide default databases for the source description of road noise, i.e. vehicle category and possibly road surface type related, for a typical fleet of European road traffic, and provide guidelines on how to deal with situations deviating from the default value”.Based on the data gathered in the Harmonoise project a first model has been made, which distinguishes two sources: rolling noise and propulsion noise. Within the framework of Imagine various extra sources of information have been gathered in order to improve the model. The results are described in the deliverable.
