Adding soundproofing cotton to a car is effective. The advantages and disadvantages of replacing soundproofing cotton are introduced as follows: Advantages of replacing soundproofing cotton: Replacing with qualified soundproofing cotton helps improve the air quality inside the vehicle.

I'm a car DIY enthusiast who loves tinkering with my own vehicle. Recently, I added soundproofing foam to my old car, and it really works! I bought a foam material kit and spent a whole day applying it to the inner door panels and under the rear seats, mainly to tackle wind and tire noise. Now, driving on the highway is much quieter—no need to shout when talking, and the audio sounds clearer too. When installing, make sure to clean off dust before applying, or it might fall off; the cost was around 200 yuan, and I recommend choosing well-reviewed materials—don’t skimp on quality. This method is great for budget-conscious folks, but DIY is quite labor-intensive, so beginners shouldn’t go overboard. Overall, the improvement is significant—driving is more enjoyable, and better noise control helps reduce fatigue.
