Abstract:

The objective of this paper is to show the variability of tire/pavement noise measured with the On-Board Sound Intensity (OBSI) method under different environmental conditions and vehicle speeds. Temperatures ranging from 40 to 90°F and speeds in the range in which tire/pavement noise becomes predominant for the overall vehicle noise were tested. The selected speeds were: 35, 45, and 60 mph. The paper presents a brief literature review identifying the gaps of knowledge about the effects of different variables (e.g., environment, vehicle speed) on tire/pavement noise. It presents a summary of different technologies used to determine noise measurements and introduces the OBSI methodology, its standards, and provides an overview of the system and software used for data acquisition. A series of seasonal field tests were conducted on a primary road in Virginia over several months. The results were analyzed to quantify the variation of tire/pavement noise with respect to the test temperature and speed. Findings confirm the previously observed trend that tire/pavement noise slightly decreases as air temperature increases. The model shows a gradient of approximately -0.05 dBA/°F. Regarding the influence of vehicle speed, the results showed that for the surface studied tire/pavement noise increases an average of 2.5 dBA for every 10 mph of increased speed.
