What Are the Reasons for Loud Car Noise?
2 Answers
Car noise is loud for the following reasons and solutions: Reasons for loud car noise: Engine carbon buildup; shock absorber failure; spark plug carbon buildup; tire aging; internal damage to the valve guide; cooling system failure; poor oil quality; engine misfire; large gaps in the cabin or vehicle body. Solutions for loud car noise: Apply sound-absorbing foam material under the engine hood; install sound-absorbing cotton material in the trunk, the bottom of the trunk, and the wheel arches on both sides of the trunk; install professional damping plates in areas prone to noise; install sealing strips inside the doors; replace tires.
Having driven for decades, I've frequently encountered issues with excessive car noise, which mainly stem from mechanical component failures. For instance, the engine may roar when it's aging or lacks lubrication, and a leaking exhaust pipe can produce a popping sound. If tires are unbalanced or severely worn, they'll hum noticeably at high speeds. Additionally, loose suspension components, such as worn-out shock absorbers, can creak over bumps. Interior parts like the glove compartment or under-seat fixtures may also rattle when loose, creating noise on rough roads. Wind noise becomes prominent at high speeds if window seals are damaged. For maintenance, I recommend regular checks of engine oil, tire pressure, and exhaust pipe seals, and visiting a professional shop for part replacements when necessary—these steps significantly reduce noise interference and enhance driving comfort.
