Baojun 730 Noise Solution?

[DiSebastian]

The main sources of car noise include engine noise, tire noise, wind noise, and body resonance. The solutions for Baojun 730 are as follows: 1. Install trunk soundproofing materials. Since Baojun 730 is an MPV model, the trunk space is very large, and when the trunk is empty, it is prone to resonance. The solution is to install soundproofing materials in the trunk, such as soundproof cotton or soundproof strips. 2. Replace with quiet tires and install soundproof materials on the wheel arches, which can significantly reduce tire noise. Replacing the sealing strips around the car can also help block some noise. 3. Install heat-resistant soundproof cotton in the engine compartment. It is important to choose high-quality soundproof cotton, as inferior soundproof cotton can become brittle under prolonged high temperatures and may even catch fire.
