Why Can Engine Noise Be Heard Inside the Car?
1 Answers
Excessive engine noise in a car can be caused by exhaust pipe leaks, tire noise, wind noise, and other factors. Exhaust pipe leaks: When there is a leak in the intake or exhaust pipe, gases escape from the leak during engine startup, causing vibrations and generating noise. Tire noise: Tire noise is produced by the friction between the tires and the road surface during high-speed driving. The level of tire noise depends on road and vehicle conditions—poorer road conditions result in louder noise. Additionally, there is a significant difference in tire noise between asphalt and concrete roads. Wind noise: Wind noise occurs when the pressure of oncoming wind exceeds the sealing resistance of the car doors and enters the cabin during high-speed driving. The faster the speed, the louder the wind noise.
