This semester project examines whether there is a potential of reducing road noise emissions with electrically powered passenger cars, and how knowledge of the effects can be used in future efforts against road noise. WHO estimates emissions from road noise as one of the biggest health problems we have, not just in Denmark, but in the entire EU, which makes this a field of interest. By examining the primary sources of road noise, being motor and rolling noise, as well as examining the noise from the electric engine and the combustion engine, it is possible to establish some criteria to be used in creating area typologies. These typologies can be used in the identification of the character of the road noise from cars driving in urban areas. Subsequently the area typologies are used in the analysis of some selected road sections and areas in Frederiksberg Kommune, to determine the character of the road noise emissions at these places. Even though this project only processes the potential effects on a theoretical level, the analysis shows that there is a possible potential of reducing the road noise with electrically powered passenger cars. This knowledge can be used in the further work with reducing road noise in urban areas
