The noise source of Corolla is mainly engine noise and wind noise on the way. If the noise is large, you can choose to soundproof the car. The whole car soundproofing is more suitable for those models with a long time, but there is no need for new cars and medium and high-end models. The double-layer soundproofing of the whole car is about 4,500 yuan, and the single-layer is about 3,000 yuan.

Generally, one square meter of soundproofing costs about 100 yuan per square meter: professional acoustic products are used in soundproofing projects to reduce body vibration, absorb the sound in the car, and isolate the noise transmission path.The sound insulation project of the system should be completed through three steps: shock absorption, noise reduction and sealing. Use vibration-dancing and soundproofing materials to achieve the purpose of soundproofing and noise reduction.

As of July 5, 2020, car soundproofing generally costs ranging from 2500 to 3900, and the specifics need to be decided according to the actual model.

The car hood is made of soundproof cotton, and the price of labor and materials in the store is generally about 200 yuan. You can also buy one on Taobao and install it by yourself. The material cost is about 120 yuan.

How much does it cost to soundproof the whole car with the engine sound of Volkswagen Touareg

1. But for those car enthusiasts who don't pay attention to the sound effect, it is not necessary to soundproofing, because The improvement of driving and engine noise is not helpful, and the phone bill is about 4,000 yuan. After the complete soundproofing of the car, the weight of the body will increase by about 40 kilograms, which may have a little impact on the power system and increase the weight.

2. The whole car soundproofing of Langyi is about 5 square meters of anti-vibration board, 7 square meters of soundproof cotton, and 5 square meters of white sound-absorbing cotton.The cost is about 1200-1,300 yuan. The construction method is roughly as follows: inside the door, bottom plate, bottom of the trunk, front wing plate. Stick the anti-vibration board first, and then apply the soundproof cotton. Both sides of the roof and trunk.

3. If the materials are imported, the construction cost of the whole car according to international standards is about 5,000 yuan.

4. The cost of car soundproofing: Car soundproofing is an improvement measure to improve comfort. First of all, by adding human shock absorption, sound absorption and sound insulation materials, the strength of the body metal plate is strengthened and resonance is reduced, so as to reduce noise.

How much is the sound insulation of the whole car of the BMW x1, the sound insulation process of the whole car of the BMW x1

The solution of the big noise of BMW x1: The biggest reason is the noise of the tires;Wind noise reduction method: most of them can be solved by installing door-side seals and door soundproofing; tire noise reduction (road noise) method: do soundproofing and reduce tire noise by blocking the propagation of tire noise to the driving compartment.

The four-door soundproofing picture of the BMW x1 is as follows: The final effect of the BMW x1 soundproofing modification is that the sound effect is 70%-80% less than that of the original car, and the tire noise is reduced by 60%-70% (my friend said that it feels like Michelin tires). The chassis noise is also much reduced, and I am very satisfied.

In order to reduce wind noise, door side seals and door soundproofing can be installed. This situation can not only reduce the wind noise and the impact force when closing the door very well, but also the wind noise heard when the original car drives at 120 kilometers per hour is equivalent to the noise at 80 kilometers per hour, and the sound of closing the door may also be further thickened.

Hello, the sound insulation effect of the BMW x1 is still good. Generally speaking, the cost of installing sound insulation in the whole car is about 800 yuan to 1,000 yuan.

The solution to BMW's loud noise is as follows: firewall soundproofing and engine cover soundproofing, the effect is obvious, but the project volume is huge and the working hours are expensive. Be mentally prepared. Second, only the engine cover is soundproof, which is effective, but the first one is not obvious! Third, check the engine to make sure it is normal.

The key source of noise is tire noise, which is likely to have a lot to do with the application of x1 to protect the lack of temperament tires. It can also be seen from the figure below that the faster the speed, the greater its noise increase.

FiveHow much does it cost for Ling Hongguang to soundproof the whole car

Hongguang does soundproofing, and the whole car is pasted with anti-vibration mats. The construction area is about 10 square meters (excluding the roof), which is equivalent to using 100 anti-vibration pads, and the price is 1600. The cost-effective practice is to focus on the chassis, that is, the construction of the inner bottom plate of the car, the outer four-wheel support body, about 70 anti-vibration pads, the price is 1120.

In summary, the whole vehicle is soundproofed, and then four silent tires are replaced. The price is at least 2,000 yuan. Finally, what you need to know is that due to cost reasons, the sound insulation effect of Wuling Hongguang s itself is not good. The above measures can only slightly reduce noise, and it is unrealistic to completely eliminate noise. After all, a car at this price can't have a good driving experience.

Wuling Hongguang s makes the whole car double-layer soundproofing, inThe physical store contract labor and materials are about 3,500 yuan. If you have strong hands-on ability, only use materials, and then build by yourself. The material fee is about 2,000 yuan. The whole car generally includes: hood part, front wing plate part, door, body side steel plate, whole vehicle bottom plate, rear door.

This car, construction of the whole car, cost-effective materials, the cost is about 1,200 yuan. The construction parts include the door, the whole chassis, the side circumference (both sides of the trunk) and the roof. The construction steps are as follows: four doors: the steel plate in the door cavity, first paste the small anti-vibration plate, and then paste the soundproof cotton on the small anti-vibration plate.
