What causes the noise when hackers are running?

Introduction to the causes of noise caused by hackers: 1. Noise of intake system: When high-speed gas enters the cylinder through air cleaner, intake pipe and valve, it will produce strong aerodynamic noise. Engine noise is mainly transmitted to the cabin through the automobile noise generated by the front fender, the hood firewall and the exhaust pipe. 2. Road noise: Road noise refers to the car noise caused by the wind cutting in at high speed, the chassis vibration caused by driving, and the road noise caused by the impact of sand on the car chassis. Road noise is mainly transmitted to the compartment through the noise generated by the four doors, trunk, front and rear fenders and front wheel arc. 3. Tire noise: Tire noise refers to the tire noise caused by the friction between the tire and the road surface when the vehicle is driving at high speed, depending on the road conditions and tire tread. The worse the road conditions, the louder the tire noise. In addition, the tire noise generated by asphalt pavement and concrete pavement mainly passes through the trunk and front and rear fenders, which is very different.
