Surface Noise Monitoring and Analysis During Chassis Dynamometer Test

This paper presents an overview of the idea of measuring the road surface by measuring noise. Current developments show that the conventional measurement of road surface conditions in motor vehicles is by considering the outside temperature, which is relatively inaccurate, considering influencing factors such as humidity, season and so on. By measuring the noise from the tire contact of the vehicle with the road surface and analyzing the results, a system can be established to more accurately record the condition of the road surface.
