Next are engine noise and tire noise. When the car is running normally, the engine noise can reach over 90 decibels, and when the tire noise speed exceeds 90 kilometers per hour, it can reach around 95 decibels. So adding a muffler to the exhaust system can reduce the exhaust noise of a car by 20-30 decibels. In terms of engines, replacing diesel engines with gasoline engines can reduce engine noise by 6-8 decibels.
