Is your car soundproofed? There is no obvious effect on the sound insulation of the car

The sound insulation of my car is good, not particularly bad, but it is not particularly good, so-so, and it usually does not feel noisy.

My car is an Elysée. Good sound insulation. Better than Polo.

The sound insulation of my car is particularly bad, driving is very uncomfortable, buzzing, very noisy, and I have been planning to buy another car so that I don't have to worry about it anymore.

I think the sound insulation of my car is pretty good, compared to other cars. Of course my car's ** is very high.

The sound insulation of my car is very good, and it is generally great that I can't hear some noise and noise outside.

My car is Buick Yinglang, and I personally feel that the sound insulation effect is OK. If you close the windows and doors in the same way, you won't feel very loud when you sit outside the car.

My car is a Mercedes-Benz car, the sound insulation effect is very good, generally I can't hear some noise and the noise outside is still great.

The sound insulation of my car is still very good, if you close the window, you can't hear the inside of the car. Excellent.

The sound insulation of my car is very good, and I deliberately did a test on the sound insulation of the car when I bought it, and I bought it after the evaluation was successful.

The sound insulation of my car is very bad, I don't know what the reason is, maybe it's because of my car, the price is relatively cheap, and it feels good.

The sound insulation of my car is pretty good. When you put ** while driving, you basically can't hear it outside. It will not have any effect on others.

The sound insulation of the whole car must be effective, but whether the effect of the sound insulation modification of the whole car is obvious is mainly affected by two factors, namely:

1. Modification technology of auto repair shops.

2. The advantages and disadvantages of automobile sound insulation materials.

It is not recommended to do the whole car soundproofing. The first is that after the complete car sound insulation, the pollution will be very large, and it will also have an impact on people's health.

The second is that the effect does not meet your expectations after the sound insulation, and it does not have the effect you imagined.

The third is that after the complete car sound insulation, the weight of the car will increase, and the fuel consumption will also increase.

The fourth is to modify the car without authorization, which will be very troublesome in the follow-up car, and if something goes wrong with the car, you have to bear it yourself.

In the process of driving, the car will produce some noise more or less, for the general family car, there is no need to modify it aggressively, and for some noise that is too loud, it will not be tolerable. I can't stand it, but I can have the sealing strip on the door.

Common materials for car sound insulation:

1. Foam sound-absorbing material.

To put it simply, the physical properties of foam with low hardness and low rebound absorb the energy (heat) of sound waves and release them slowly. Of course, the heat of sound waves is very small.

2. Shock-absorbing composite materials.

Shock-absorbing composites are composite materials that can absorb and convert vibration energy into other forms of energy (such as heat energy) and dissipate them, thereby reducing mechanical vibration and reducing noise. In fact, the shock absorber plate we usually use is a shock-absorbing composite material!

3. Soundproof cotton (heat insulation cotton).

Sound insulation cotton is not only the role of sound absorption, more importantly, it has a relatively good heat insulation effect, after pasting in the hood of the car, it can avoid the high temperature generated by the engine directly to the hood, so that the paint on the hood can be protected, the speed of aging can be slowed down, and the rain can also avoid the rapid evaporation of rainwater on the hood when it rains, resulting in fog that affects the line of sight. Safety first, what should be done or what must be done!

It has obvious effects, you can use a decibel meter to do a test before you do it, and then do a test after doing it, there is still a big difference.

There is still a certain effect. But it is also limited to the local sound drop do not have too high expectations, wind noise, tire noise, engine noise, sound insulation good cars generally have superior manufacturing pliers tailored welding process, as well as some good sound insulation layout.

The car is definitely effective in soundproofing, to give a simple example, driving a van is compared with a million-dollar luxury car, sitting in the car, it is obvious that you can distinguish between soundproofing and not soundproofing.

Is the car soundproofed (is it necessary to do soundproofing in the car) The car does not do soundproofing. Car sound insulation is divided into local sound insulation and whole car sound insulation, some vehicles, the sound insulation effect itself is not bad, or just a local sound insulation is not in place, at this time there is no need to do the full pants source car with late sound insulation, as long as the sound insulation for a certain position will have a great effect. Car noise is divided into low, medium and high frequency, not all noise can be isolated as desired, such as the noise of the starting Hu Xing machine, sheet metal vibration and other noise belonging to the medium and high frequency, those can be separated by sound insulation, and like tire noise, especially the sound of the exhaust pipe, which belongs to the low frequency, it is often difficult to isolate.

Millions of car purchase subsidies.

Useful. The benefits of sound insulation for cars are:

1. Sound insulation: car sound insulation can reduce the noise of the car engine, and can also block the abnormal sound of the body, as well as the impact of the car's tire noise and wind noise, especially for passengers, the car sound insulation is not good, which will seriously affect the comfort of the car, and for the driver, the noise is too loud, which will affect the normal driving sleepiness.

2. The sound effect is better

People who like to modify will make some modifications to the audio of the car, after the car is soundproofed, it prevents the transmission of noise, makes the sound effect of the car better, and can provide the driver with a more comfortable driving environment, which is not easy to get sleepy.

3. Heat insulation: The heat insulation of the car can maintain the temperature in the car in the winter and will not let the heat in the car dissipate, and in the summer, it can avoid the damage to the precision parts in the car due to long-term exposure to the sun.

4. Body strengthening:

The car does sound insulation engineering, generally under the hood of the car, on the door and in the trunk, these are the places that are more likely to be damaged on the car.

Car soundproofing is useful. First, the car needs to be soundproofed, so you must choose a professional and reliable place, otherwise it will cost a lot of money, and it is very likely that people will just stick a few sticks with the so-called soundproof materials at will. To know that car sound insulation is a system engineering, we must know the best of car noise, and then step by step.

Car sound insulation can not only reduce the noise when driving in the car, but also improve the sound pressure and timbre of the car stereo. Now, after nearly 30 years of development, automotive sound insulation equipment is now mature and perfect, and then the best car sound insulation products can be accepted by most people. The location of the sound insulation structure of the whole vehicle is:

Car hoods, fenders, four-doors, cab floors. Vehicle sound insulation modification is divided into partial sound insulation and vehicle sound insulation, and sound insulation materials are also different. Some people think that the sound insulation effect of the whole vehicle will be significant, but specifically it is engine noise, sheet metal vibration, etc.

It is a medium and high frequency noise and can be isolated by sound insulation, while tire noise, especially the sound of the exhaust pipe, belongs to the low and medium frequencies and is usually difficult to isolate. Millions of car purchase subsidies.

【Pacific Automobile Network】Useful. According to the performance of the vehicle, the corresponding road conditions, and the requirements of use, the engine noise generated by the car, the resonance sound of the vibration between the tires and the road surface, and the friction sound generated by the extrusion of the components in the cabin due to clearance or aging are carefully treated.
