What Are the Causes of Car Noise?
2 Answers
The causes of car noise are: 1. Engine noise due to carbon deposits, damaged damping components, or aging seals; 2. Tire noise from aging and hardening; 3. Noise caused by pressure changes from airflow separation around the car body; 4. Noise from the interaction between air intake through gaps in the cabin or body and the surrounding airflow; 5. Faulty shock absorbers causing abnormal sounds when driving on uneven roads. The solutions for car noise are: 1. Add lubricating oil and remove carbon deposits from the engine; 2. Replace or top up engine oil and check for valve leaks; 3. Replace tires; 4. Inspect shock absorbers for oil leaks.
There are many causes of car noise, and as someone who has been driving for many years, I think there are several common ones. A loose belt in the engine area will squeak; a leaking exhaust pipe makes a loud roaring sound when accelerating; uneven tire wear or low tire pressure causes a humming noise at high speeds, affecting driving comfort. Damaged bearings produce a creaking sound when turning; thin brake pads will screech when braking. Also, a stuck electronic fan makes a clicking sound; a loose suspension system clatters over speed bumps. These issues should be repaired promptly, as noise is a signal of minor problems that could lead to major failures if ignored. Regular maintenance can prevent these issues, especially by paying attention to changes in sound during idle and acceleration, and seeking a technician's help immediately.
