【 摘 要 】

Traffic noise is an important evaluation index of urban environmental quality. The level of traffic noise is affected by many environmental factors. Compared with close proximity method (CPX method) in measurement for calculating temperature coefficient, using statistical pass-by method (SPB method) is more suitable for traffic noise evaluation. In order to verify the influence of temperature on road traffic noise, we use SPB method and light vehicles to track and test different types of road noise in a period of time, and record the road temperature and air temperature at the same time. The experimental results show that the vehicle pass-by noise decreases with the increase of temperature, and the noise level of porous asphalt pavement changes little with temperature compared to dense graded pavement.
