What Causes the Sound of Rain-Like Noise in a Car?

[DelElle]

Car rain-like noise may be caused by the last section of the exhaust pipe's muffler making noise or the shock absorber rubber sleeve being damaged. More details about mufflers and shock absorbers are as follows: 1. The car muffler is a device that prevents the sound emitted by the car from propagating while allowing airflow to pass. It is the main component for eliminating aerodynamic noise and the most important device in the car's exhaust system for reducing noise. When using a muffler, it is necessary to choose materials that are fireproof, moisture-proof, and corrosion-resistant. Generally, the greater the noise reduction of the muffler, the higher the pressure loss and price. 2. The car shock absorber can improve the smoothness and comfort of the car's ride and reduce the impact force on the car body. Shock absorbers are usually installed in the car's suspension system. The performance of the shock absorber directly affects the car's driving stability and the service life of other components. When the shock absorber rubber sleeve is damaged, the damping effect is reduced, leading to the appearance of noise.
