The Genuine Sound of Electric Vehicles: Road Noise

The sound of a vehicle is composed of several noise sources, such as drivetrain noise, road noise, and wind noise. The conventional vehicle’s interior sound is mainly dominated by drivetrain noise, especially the internal combustion engine (ICE). In the process of electrification, the road noise generated through the rolling contact of tire threads and roadway is becoming more prominent and even the primary noise source due to the elimination of ICE. Furthermore, the road noise dictates the traffic noise in the urban area. Thus, there is a need to reduce road noise further. In this talk, we will discuss the generation mechanisms of road noise and the associated measures for reduction purposes in the automotive industry, focusing on the latest approach.
