How to solve the noise problem of Soueast DX3?
1 Answers
Soueast DX3 noise is mainly caused by the lack of sound insulation cotton in the engine compartment. It is recommended to add heat insulation cotton to the engine compartment cover and other areas to reduce the noise to a certain extent. The following are the corresponding solutions for car noise: 1. Engine noise: The vehicle engine is a source of noise, and its noise varies with the engine speed. Advanced sound-absorbing foam materials can be installed on the engine cover, which not only suppresses vibrations caused by the hood but also absorbs a large amount of noise, with noticeable effects. 2. Tire noise: Tire noise is generated by the friction between the tires and the road surface during high-speed driving. The level of tire noise depends on road conditions and vehicle conditions. Poor road conditions result in greater tire noise, and there is a significant difference between asphalt and concrete roads. Tire noise is a type of structural noise, mainly caused by vibrations. The most reasonable solution is vibration damping. Adding damping plates combined with sound-absorbing pads can effectively reduce road and tire noise. 3. Wind noise: Wind noise occurs when the pressure of the oncoming wind exceeds the sealing resistance of the car doors during high-speed driving, entering the cabin. The faster the driving speed, the greater the wind noise. You can install or replace the door sealing strips, as they are rubber products that age over time, leading to reduced sound insulation and sealing effects.
