Is it necessary to sound sound in a car? What are the advantages and disadvantages of doing it?

Whether it is necessary: It is very important for car enthusiasts who have installed car audio, especially those who emphasize the hearing effect, it is very important to do the whole car sound insulation, because car sound insulation can not only improve the sound quality of the speaker, but also play a role in preventing tire noise, road noise, wind noise, about 3 to 5 decibels.

Advantages: noise reduction, improved sound quality, and thermal insulation effect (when turning on the air conditioner, due to the good thermal insulation effect, it can save fuel consumption).

Disadvantages: After the complete car sound insulation, the weight of the body will increase by about 40 kg, which may have a little impact on the power system, and the weight will increase and fuel consumption will also increase. But the fuel consumption of this weight is far less than the amount of oil saved by the air conditioner.

Is it necessary to sound sound in a car?

Whether to do sound insulation, depends on the subjective feeling of the driver on the noise of the car, some people are not sensitive to noise, open Xiali, Qiyun these noisy cars, there is no discomfort. There are also people who are very sensitive to noise, and when they drive about 200,000 Magotan cars, Regal will also feel uncomfortable in their ears, and then they need to do sound insulation treatment.

What are the advantages and disadvantages of doing it?

Advantages: The noise level at a speed of 90 kilometers is equivalent to the sound at a speed of more than 50 kilometers now, and the car can feel much quieter;

The sound of the car has been improved (before listening to songs, you had to adjust the volume to 8, and after the sound isolation, you can adjust the volume to 5 or 6), and the bass is lower and the treble is purer;

At the same time, the sound insulation material has the effect of thermal insulation, which can make the car more energy-saving, and can be clearly felt when the air conditioner or heater is turned on;

Enhance the flexibility of the steel plate of the body and reduce the damage to the car in the event of an impact.

Disadvantages: After the whole car is completed, the weight will be increased by about 40 kg, which consumes some power to a certain extent, and the acceleration time of 0-100 kilometers may be extended by seconds.

Fuel consumption increased by 100 kilometers (running high-speed tests), and there was no increase in urban tests (because sometimes there were several traffic lights on the road, and fuel consumption was raised at idle).

Advantages: The previous noise problem will be solved, of course, it is to choose a professional brand, do not be greedy for cheap to choose some unprofessional products, not environmentally friendly. The driving is more comfortable, the original car audio is better, the original car sheet metal is more solid, heat insulation, etc.

Disadvantages: weight gain, some sound insulation contains asphalt, very heavy, choose light weight and efficient. To dismantle the car, find a professional shop, and do not be disassembled and assembled by the roadside store, which will cause abnormal noise and damage.

Take a look at Daneng sound insulation, there are stores online and offline. You can find out.

I agree with what I said upstairs, whether you need to do sound insulation or not, it all depends on your subjective feelings and pursuit of car noise.

The specific advantages and disadvantages are already very clear from what was said upstairs, and they will not be described here.

Talk to you about the common problems of car sound insulation? The principle of vibration and sound insulation of damping and damping plates, how should sound insulation be done?

All noise is produced by the vibration of objects, without vibration there is no sound, and the generation and propagation of sound are inseparable from vibration. Therefore, controlling vibration is one of the most important and basic ways to solve noise. The appearance of sound insulation and vibration damping materials does not represent the performance of the materials.

The actual effect of a material with a very fancy surface treatment is not necessarily better. The following is the principle of vibration and sound insulation of damping and damping pads** to help you understand the principle and performance of various damping and vibration blocking materials.

In order to create a quiet driving environment, many car owners will choose to do car soundproofing after buying a car. So is it necessary to do car soundproofing? What are the pros and cons?

First of all, some car owners are more sensitive to sound and are susceptible to noise. In this case, it is recommended to do car soundproofing. On the one hand, it can reduce noise, and on the other hand, it can improve the sound quality in the car and create a more comfortable driving environment.

And because of the better sealing, the insulation effect is also good, and the fuel consumption of the air conditioner is naturally lower. And the noise decibels generated by different models are not the same as Kai Lingling. If the engine noise is too loud, and it will even affect the normal driving, it is recommended to do car sound insulation.

Secondly, the disadvantages of sound insulation are also very obvious. First, the weight of the car will rise to a certain extent, affecting the power transmission of the car. The acceleration time of 100 kilometers will be extended by about a second.

If you pay more attention to the driving feeling of the car, it is still not recommended to do sound insulation. Second, to do sound insulation, you need to remove some car parts and then fill in some sound insulation materials. In the process of disassembly and assembly, if the operation is not professional, it is likely to affect the original overall performance of the car, and even the circuit of the whole vehicle, resulting in potential safety hazards.

Finally, car sound insulation is generally divided into vehicle sound insulation and local sound insulation. The two sound insulation methods have different effects and are very different. Generally speaking, the whole car is the best and the most expensive, but it is not recommended that all models do the whole car sound insulation.

Because some vehicles have very good sound insulation, but because the local sound insulation is not in place, there will be noise and laughter. At this time, we only need to do sound insulation treatment on a certain part, and the effect will be very obvious. And of all the noise generated by the car, only a part of it can be isolated, such as the engine noise and the noise caused by the vibration of car parts, while the tire noise does not seem to be completely isolated.

Therefore, if you choose to do car noise isolation, you still need to have a comprehensive understanding of car noise. To sum up, there are pros and cons to car sound insulation, and you have to choose according to your actual needs. If you choose to do sound insulation, it is recommended to go to some more formal and professional stores, which can reduce the damage to the car.

I believe that many car owners have a certain understanding of car sound insulation, but for the highest car sound insulation known as the best, many car owners have concerns when doing it, because there are many car owners around them who regret doing the whole car sound insulation, because the effect is not obvious. Car sound insulation is not all good, so what are the disadvantages of car sound insulation? First of all, the car should be soundproofed in a professional and regular place.

Otherwise, it will cost a lot of money, and it is likely that people will just put a few layers of so-called soundproofing materials on it. Obviously, car sound insulation is a system engineering, and it is necessary to know the best of car noise, and then step by step. Otherwise, if your car is soundproofed, people will immediately dismantle it for you and paste a few layers of soundproof materials, which is very unprofessional.

Automobile sound insulation is divided into local sound insulation and vehicle sound insulation. Not all cars are suitable for full car soundproofing. Some cars have good sound insulation, or just some local sound insulation is not in place.

At this time, there is no need to do the whole car soundproofing. Just do it in a targeted way. Some people think that the sound insulation effect of the whole vehicle will be obvious, but in fact, engine noise, sheet metal vibration and other noises belong to medium and high frequencies, which can be isolated through sound insulation, while tire noise, especially exhaust pipe noise and other noises, belong to medium and low frequencies, which are often difficult to isolate.

In addition, in order to pursue height, it is necessary to remove the door panels of the four doors, four wheel arches, seats, and even the center console, and then lay various sound insulation materials and shockproof panels. , and then put the removed items back, which is equivalent to a major operation on your vehicle. If it is an unprofessional tuning shop, it is likely to bring sequelae to your vehicle, and it will be troublesome at that time.

So is it necessary to do sound insulation for the whole car? Bian Xiao thinks that new cars don't need to be done, mid-to-high-end models don't need to be done, and old models can be done, but they must go to a professional and regular modification shop, otherwise it will be a waste of money in the end. Of course, this is just Bian Xiao's personal opinion, for reference only, the decision is still in your hands.

In summer, when the temperature is relatively high, the glue begins to flow, and the car is full of flow, and it is not easy to clean, and after high temperature exposure, it will also produce peculiar smells.

To do sound insulation for cars, you must choose a professional and regular place, otherwise it will cost a lot of money.

It is likely that people just casually put a few layers of so-called soundproofing materials on it and it will be done. To be clear, car sound insulation is a system engineering, you need to understand the car noise, and then step by step. Otherwise, if your car is soundproofed, people will immediately help you dismantle the vehicle, and then paste several layers of soundproof materials, which is very unprofessional.

Car sound insulation is divided into local sound insulation and whole car sound insulation, not all vehicles are suitable for the whole car sound insulation, some cars their own sound insulation effect is not bad, or just a local sound insulation is not in place, at this time there is no need to do the whole car sound insulation, as long as it is targeted to do it.

The sound insulation of the whole car needs to remove the door panels of the four doors, the wheel arches of the four wheels, the seats, and even the center console in pursuit of height, and then lay various sound insulation materials, shock absorbers, etc., and then put the disassembled things back on, which is equivalent to a major operation on the vehicle. New cars don't have to be done, mid-to-high-end models don't have to be done, and older models can be done, but you must go to a professional and regular modification shop, otherwise it will be a waste of money in the end.

There is no need for the car to do sound insulation, reasons: 1. Most of the current car interior parts are snapped, and they are loose after disassembly, which means that there will be a little more or less abnormal noise when driving on bumpy roads, so it can only be counterproductive;

2. If the connection part is not installed to the original standard, it will lead to ash leakage, for example: the plastic paper inside the door trim panel is used to prevent dust from entering, if it is not properly disassembled and assembled, it will cause the glass regulator to lift unsmoothly, the door lock hairpin, etc., replaced with a so-called soundproof paper, the sealing effect is definitely not as good as the original plastic paper;

3. The so-called sound insulation material is just made of asphalt for paving, the temperature in the car is higher in summer, sometimes the vehicle can not avoid parking under the scorching sun, and the vehicle is parked in a small bush under the scorching sun in summer, and the temperature in the car is at least about 60 degrees;

4. It is conceivable that the heat insulation material will release how much poisonous gas will be released by the action of high temperature, and if a pregnant woman sits in such a car for a long time, how much impact will it have on the fetus, and the possibility of causing malformations is also there.

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.
