The world is rich and colorful. After living in a busy environment for a long time, you will inevitably want a quiet place of your own. Cars are a very suitable place to be alone, but not every car has such a good sound insulation effect. For those cars with poor sound insulation effect, it is really important to modify the sound insulation of cars.

The protagonist of this modification-Volkswagen Magotan

All of them are made of Japanese landscape sound insulation materials, including landscape sound insulation and shock absorption guard+low frequency guard+sound absorption guard. I don't want to talk about the above picture, let's talk about the range hood first.

The hood of the original car is very thin, baked by the engine and easy to age. There are also many holes, which are easy to cause wind noise and greatly affect the driver's mood. Professional and technical personnel use landscape shock absorber+sound absorber for sound insulation. Stick the sound insulation material on the hood with a special roller, and then compact it to stop the vibration of the hood. Silencing white cotton can effectively absorb the noise of range hood.

The front and rear fenders are the parts prone to tire noise, which are closest to the tire and are prone to tire noise when the tire is driving. Technicians should clean the leaves first to prevent the sound insulation material from falling off and let the sound insulation material play its greatest role.

We can see that the chassis sound insulation material of the original car is very old, dirty and has no sound insulation effect. Asphalt material is a kind of toxic environmental sound insulation material. The master removed the toxic asphalt shockproof board from the original car, cleaned it, and then cleaned up the dust particles. This can avoid the impact of particles left on the chassis, resulting in insufficient sealing of sound insulation materials and affecting the sound insulation effect.

The first floor of the chassis adopts mountain and water damping guard plate for sound insulation, which can not only effectively reduce vibration and noise, but also strengthen the sheet metal.

The second layer of landscape sound-absorbing shield has a sealed sound-absorbing effect. Chassis sound insulation is mainly to suppress the road noise caused by the friction between tire and road surface. After sound insulation, the road noise and tire noise are obviously reduced.

Four doors sound insulation is the most basic and important thing to do. Four-door landscape shock absorber+sound absorber sound insulation is to provide a good speaker, which can not only reduce the * * * vibration when the speaker sounds, but also form a * * * speaker inside the door panel.

Write at the end: poor sound insulation is a common problem of almost all cars, which has been seriously affecting the health of drivers and passengers. Eating less dinner and snacks can upgrade the sound insulation of mountains and rivers and give the whole family a healthy and comfortable interior environment. Why not?
