Speed dependency of temperature effects on road traffic noise

Abstrakt

Recently, a new literature review on the influence of temperature on tire/road noise became available, based on a compilation of large amounts of data from empirical research. This review showed that the effect of temperature is roughly double of that previously assumed and taken account of in international standards. This makes temperature one of the main sources of error in measurement results. Furthermore, it suggested that an additional refinement of the correction approach may be required to improve the accuracy of measurements. As a first attempt for this refinement, this article focuses on the speed dependency of temperature effects. Some past work has detected an influence of speed on the temperature effect, but did not succeed in quantifying this influence or in describing the exact pattern of speed dependency. This work aims to fill this gap by (1) investigating speed dependency of temperature effects on tire/road noise, (2) estimating the temperature influence on noise generation mechanisms together with their change with speed, and (3) evaluating the speed influence on overall road traffic noise by including a propulsion noise component while using a new European traffic noise emission model. The article concludes by proposing a method to deal with speed dependency of temperature effects on both, CPX (or OBSI) and SPB measurements, with the ultimate goal of increasing the accuracy of measurement results.
