What Causes Excessive Car Noise?
2 Answers
Excessive car noise is primarily caused by issues with engine components and door components. The specific details are as follows: Engine-related components: It is not necessarily the engine itself that is problematic, but rather the external soundproofing equipment may be damaged. For example, the soundproofing cotton may be worn out, or the soundproofing components may have aged. Alternatively, the engine mounts may be damaged, whether due to normal wear and tear or abnormal damage. Another possibility is that a certain screw related to the engine is loose, or a rubber gasket is damaged. However, when the car is running at high speeds, the increase in noise becomes particularly noticeable. Door-related components: These include screws inside the door and sealing strips. Since the doors are very close to the cabin, any noise from them tends to be more noticeable. When the sealing strips age, their soundproofing effectiveness decreases, making it easier for external noise to enter the car.
That day while driving home, I suddenly noticed a buzzing sound in the car that was so loud it hurt my ears. I figured there could be several possible causes. The most common issue is tire problems – if the tread is worn down or the pressure is too low, the noise gets really loud at highway speeds; my old car had this issue and needed tire replacements several times because of it. Another possibility is an exhaust system leak – if there's a hole in the muffler, engine noise can directly enter the cabin. Then there's bearing failure – when the wheel bearings wear out, the noise increases significantly; I've experienced this before where stepping on the gas would cause a loud buzzing. Worn or loose engine belts are another culprit, creating squealing noises while driving, requiring inspection of the tensioner pulley. Lastly, don't overlook suspension components – loose shock absorbers or linkages can cause clunking sounds when going over bumps. I'd suggest doing some basic self-checks first, like listening for the noise source when starting the car in a quiet place. If the noise persists, get to a repair shop promptly to prevent minor issues from turning into major repairs that could compromise driving safety.
