How much is the sound insulation of the whole car, my car is a Toyota Corolla, I think

Generally speaking, the sound insulation of the whole car depends on its materials and specific projects, generally speaking, it starts at 2000 yuan.

Use a little better of the material, that is, around 1500-2500, which depends on your personal needs.

Hello! For the sound insulation of the whole car of this car, it depends on what kind of sound insulation cotton you choose, like the general one is also about two or three thousand, this can also go to the modification shop to consult the specific sound insulation cotton**.

It also depends on what material you use, and the normal general cost is about 2,000 yuan.

Hello, if you consider doing the whole car sound insulation, ** is generally around two thousand. It's not too cheap, in fact, if the noise is not very loud, there is no need to do the whole car soundproofing. Of course, the effect after doing it is still very good.

Hello, the sound insulation of the whole car of Toyota Corolla is about 1500, you can go to the decoration city, you can do it directly.

Specifically, depending on what kind of soundproof cotton you use, there is a difference in **, generally speaking, the whole car is not less than 1500 yuan for sound insulation, plus the engine and wheels.

Generally speaking, if the whole car is soundproofed, the ** aspect is relatively high, and it will cost about 3,000 yuan if it is almost all down.

Hello, under normal circumstances, it is about 2000, and the whole car soundproofing cotton is done once, and it is recommended to go to the local professional store to do it

Hello, if the whole vehicle is soundproofed, it takes about 1500 to use the soundproofing cotton of ***, and the ordinary soundproofing cotton is about 1000, and the soundproofing effect is still good after the vehicle is soundproofed!

Hello, now the sound insulation of the whole car is generally about 2000 yuan, and it is very good to use 3m shock absorbing sound insulation cotton.

Hello, if this vehicle is soundproofed, it should be about 2,000 yuan. You can go to the 4S store first and ask**.

Hello, the sound insulation of this car is about 1000, depending on the material chosen, for reference.

The cost of sound insulation of the whole car depends on the specific materials, and generally it starts at 2000

For car owners who pursue first-class **, upgrading sound insulation should be synchronized with sound. A good layer of sound insulation can not only give you a quiet and comfortable driving environment, but more importantly, let your stereo play the most perfect effect. There are six main categories of car noise:

1.Engine noise: When the engine is running at high speed, the noise is continuously transmitted to the vehicle body through the firewall, chassis, etc.

2.Noise generated by body resonance: The body sheet metal is thin, which causes the car to produce iron sheet resonance when driving on bumpy roads or at high speeds.

3.Chassis noise: The noise generated by the suspension system on bumpy roads and at high speeds is quietly transmitted to the body through the chassis.

4.Tire noise: The noise caused by the friction between the tires and the ground when the car is driving at high speeds.

5.Wind noise: Generally speaking, the wind noise generated by different car models is different.

Wind noise varies depending on the speed of travel (the wind noise usually starts to increase after the car reaches 100 km/h). Due to design reasons, the drag coefficient of the car cannot be changed; Wind noise is introduced into the car body through the gap in the door, and it is difficult to reduce it completely and effectively.

6.In-box resonance: Resonance refers to the sound resonance void produced by two or more identical audio voices colliding with each other within a certain range. Due to the small space in the car, the noise cannot be effectively absorbed, and it collides with each other to produce resonance.

The rider chose a pilot with good soundproofing - car soundproofing (Daneng soundproofing), and then after audition, it was decided to install French 165VRS and 165A1. Immediately after that, the Toyota Corolla was retrofitted without damage. For car owners who pursue first-class **, the sound of the upgrade balance should be synchronized with the sound.

A good layer of sound insulation can not only give you a quiet and comfortable driving environment, but more importantly, let your stereo play the most perfect effect.

The soundproofing is divided into two layers. The first layer of sound insulation is mainly to thicken the door panels to reduce resonances.

The main function of the second layer of sound insulation is to reduce road noise, isolate external heat, and give full play to the best effect of the speaker.

The trunk is also two-tiered. The first layer of sound insulation reduces resonances and isolates exhaust pipe noise.

And then there's the hood. Many people say that the soundproofing in front of the car should be done inside the firewall. Here, I recommend not to do the soundproofing of the firewall.

The original car has been soundproofed by a firewall when it leaves the factory, and the original firewall is well sealed. If you take it apart and put it back on, you may not be able to achieve that level of sealing. Loose parts are more susceptible to vibration and noise.

So, in fact, it is enough to insulate the hood at the front. Hood sound insulation can be sound and heat insulation.

Soundproofing is done here.

The Corolla is a product of Toyota, and the domestic Corolla is already its ninth generation, especially its VVT-i engine, which is the first Toyota domestic model to use this engine. After domestic production, the performance of this car is still in full swing and has become a product of FAW Toyota. The Corolla is a classic model, it is always changing, constantly updated, and enduring.

Whether it's styling, handling, or comfort, the Corolla is unbiased. The little jasper is petite and cute, but the ladies are more relaxed and generous. As a result, the connotative Corolla has gained the most widespread recognition and ranks among the top 10 in the Beijing News Super Car Selection.
