The noise generated by the rolling contact of the tire on the road surface is mainly generated by the air pumping action between the tire and the road surface during high-speed running and the vibration action of the tire. When the tyre rolls, air between the tyre and the road surface acting surface is suddenly extruded from the compressed tyre pattern grooves and small gaps of the road surface, and partial cavities are compressed again in the closed and semi-closed cavities when the tyre is in contact with the road surface. At the moment when the tire is separated from the road surface at the ground-contacting rear edge of the tire, the volume of the tread pattern groove and the small gap of the road surface is rapidly expanded and recovered, air is sucked into the expanded cavity to form a noise similar to that of a vacuum cup which is rapidly uncovered, so that the air rapidly enters the cup to generate 'popping' noise, and meanwhile, compressed air in the closed or semi-closed cavity is sprayed out, and the noise generated in the process is called pumping noise.
Grooving on the cement concrete pavement can improve the friction coefficient of the pavement and play a good anti-skidding role. However, the driving of the grooves on the cement concrete road is very noisy, and the noise generated by the "air pumping effect" due to the grooves when the tires interact with the grooves on the road is called as the noise of the grooved road.
