The Effect of Temperature on the Tire-Pavement Noise

온도가 타이어 소음에 미치는 영향

Tire-pavement noise is a significant portion of noise coming from road vehicles and is therefore a logical focus of efforts to reduce overall traffic noise. A small but significant reduction of noise level with positive temperature increases was observed for some tires. The reduction was evident in two of the tires at 53 km/h and five of the tires at 80 km/h. The temperature gradient of the different tires at 80 km/h range from -0.07 to +0.01 dB/$^{\circ}C$. Frequency analysis of the tire noise identified that noise content in the range of 1,300 to 1,900 Hz is particularly sensitive to temperature changes.
