What Causes Loud Noise When Driving at High Speeds?
1 Answers
When driving at speeds exceeding 100 km/h on highways, the noise inside the vehicle can become very loud, primarily due to the following reasons: 1. Wind noise: The intensity of wind noise is related to the vehicle's body shape, which is determined by design and does not change suddenly. If the wind noise suddenly increases during driving, it is mostly due to localized deformation or significant damage to the vehicle body. Apart from the body generating wind noise, at high speeds, air being sucked out through various gaps in the cabin can also produce loud sounds. If the wind noise fluctuates, it is advisable to check the rubber sealing strips around the doors for any air leaks. Reducing wind noise mainly involves improving the vehicle's sealing. 2. Tire noise: The level of tire noise is directly influenced by speed, load, and tire tread patterns. For passenger cars, 70% of tire noise comes from tread design. If tire noise is excessive, first ensure the tire pressure is within the appropriate range, the tires are not damaged or excessively worn, and the vehicle is not significantly overloaded. 3. Engine noise: This is related to the engine's design and operating condition, with the most critical factor being engine maintenance. Good lubrication and well-functioning components are prerequisites for smooth engine operation. When the engine is in optimal condition, its actual noise level reflects the vehicle's design standards.
