Among these noises, the most difficult one is car noise. Theoretically, the problem of domestic noise can be solved at the same time by dealing with car noise. Of course, low-intensity construction noise can also be solved. However, I can only say that the noise generated by piling is very difficult to deal with at present. Except that they stopped working within a limited time, we can't decorate our home into the sound insulation standard of the audition room.
First of all, we need to understand a basic concept: decibel, which is the unit of sound pressure level (symbol: db). Every time the sound pressure doubles, the sound pressure level increases by 6 decibels. 1 dB is the sound that the human ear can just hear. Generally speaking, sounds below 20 decibels are considered quiet. Of course, generally speaking, sounds below 15 dB can be considered dead. 20-40 decibels is about a whisper in a couple's ear. 40-60 decibels belong to our normal conversation voice. Above 60 decibels, it belongs to the noisy range. When it reaches 70 decibels, we can think it is very noisy and begin to damage the auditory nerve. Above 90 decibels will damage hearing, and stay in the space of 100- 120 decibels. Unless there is an accident, people will be deaf for a minute. Among them, the noise of cars varies from 80- 100 decibels. Take a car with a noise of 90 decibels as an example. At a distance of 100 meters, noise of 8 1 decibel can still be heard (the above standards will vary according to environmental differences, not absolute values).
The magnitude of traffic noise is affected by the following factors:
1. The higher the traffic volume of vehicles on adjacent roads, the greater the noise. The noise of the main road will definitely be much louder than that of the municipal roads in the community.
2. The higher the speed of the adjacent expressway, the greater the noise.
3. The higher the proportion of heavy vehicles, the greater the noise, such as container trucks (container trucks).
4. The lower the quality of highway pavement, the greater the noise. With the same pavement quality, the noise with speed bumps will be louder than that without speed bumps.
The closer to the road, the louder the noise. When the same heavy truck passes by, the residential building (plane linear distance) at a height of 5.5 meters from the highway at 10 meter will be attenuated by 0.3 dB, at 30 meters by 4 dB, at 50 meters by 6 dB, and at 100 meter by 8.9 dB.
6. At the same distance from the expressway, the higher the floors of ordinary houses, the greater the noise. (At present, there is no upper limit data, and the possibility of weakening after reaching a certain height is not ruled out, but at present, it is generally the case for the top 32 floors. It is wrong to think that living higher is far away from noise.
7. Those with road noise barriers are lighter than those without noise barriers.
8. The influence of buildings is lighter than that of no buildings.
To solve traffic noise, we have to solve it and see how many kinds of car noise there are. Generally speaking, they can be summarized as follows:
1, the sound of automobile tires rubbing against the ground. This kind of sound is basically bass, accompanied by vibration. This situation is especially adjacent to the fact that concrete roads are more serious than asphalt roads.
2. The sound of automobile engine, exhaust pipe and automobile transmission system. The greater the horsepower, the longer the car limit and the stronger the noise.
3. Load impact caused by car horns, wind resistance and brakes, speed bumps and the sound of vehicle vibration.
Knowing the main sources and classification of noise, I can solve them one by one.
1. The best way to deal with noise is to close the window. Whether you have a single window or a double window, sealing is the most important thing. The bearing capacity of a barrel is determined by the shortest sawdust, and the sound insulation effect is determined by the weakest link. From the current technical level, it is the most effective decoration scheme to use plastic steel windows as sealing means. For users who have adopted aluminum alloy, it is necessary to ensure that the aluminum alloy frame sealing strip is intact. Relatively speaking, the sealing performance of aluminum alloy windows is worse than that of plastic steel windows.
2, the window seal is solved, the next step is to make it more sealed, after all, sound insulation does not mean sealing, but also depends on sealing performance. It is a very effective method to use insulating glass in plastic steel windows. Because the loudest part is often the high-pitched part, and the high-pitched part travels in a straight line, most of it can be reflected by the glass, and the non-reflective part can be consumed by the insulating glass. However, we should pay attention to profiteers ... >>
Question 2: How to soundproof the room windows when living on the roadside? (Cheap and affordable) If you can't change the window glass, change the curtains. .
You see, in a hotel room near the airport, it's much quieter to close the curtains than not to close them. This makes use of the sound insulation effect of curtains.
Of course, this is related to the material composition of the curtains. Generally, this kind of curtain should be found in larger curtain shops.
Carpets also have sound absorption function.
Question 3: How to effectively solve the noise and sound insulation methods of building windows near the road? Last September, I bought a second-hand house on the eighth floor of a residential area in Zhengzhou CBD, and it was renovated in June 5438+ 10 this year. However, it is unbearable that I haven't slept well for several days since I moved in on the 2nd of this month. Because the house is located on the edge of the community and close to the road, it has to endure huge noise pollution, speakers and roar from morning till night. Moreover, when I decorated the room, I changed sound insulation glass and soundproof windows, but the effect was very general. Especially the engineering vehicles, with the vibration, make a huge "rumbling" sound, which is simply unbearable. Of course, the house has just been renovated and it is impossible to sell it. I blame myself for not thinking clearly. So I want to consult an expert to see what can be done to solve the road noise problem in my home. I am very grateful. Please. Now the buildings in the city are getting taller and taller, and there are more and more cars on the road. At present, the sound insulation problem of indoor decoration has become a very important thing, but the sound insulation problem is not a simple decoration problem, it also involves acoustic problems. To solve the problem of sound insulation, we should distinguish what kind of noise is caused and adopt different methods to solve it. Knowing the main sources of noise, we can solve them one by one. 1, the window seal has been solved, and the next step is to make it more sealed. After all, sound insulation is not equal to sealing, but also depends on sealing performance. It is a very effective method to install soundproof windows, fully consider the sealing and adopt special glass used in space vehicles. Because the loudest part is often the treble, which travels in a straight line, most of it can be reflected and absorbed by this glass. 2. For the vibration and friction of these bass, we can use carpets, fabrics and even sound-absorbing cotton to weaken their influence on the room. Rubber pads at the foot of the bed can also reduce vibration. At the same time, mattresses with palm pads are better than Simmons with springs, not to mention hard beds. 3, of course, no matter how to do sound insulation, don't forget proper ventilation, too closed environment is as unhealthy as sleep. The side facing the noise should prevent noise, and the opposite side should be properly ventilated. Of course, you don't necessarily have to open your windows properly, because noisy things have certain repercussions, which may affect the building behind you and spread back to your building. 4. Now some houses use light bricks (hollow bricks) as external walls, which have poor sealing performance. If your roadside has a great influence on you, you can also make a sandwich of wood square (light steel) and sound-absorbing (sound-insulating) cotton with gypsum board on the wall near the road, and then decorate the surface with wallpaper (of course, you can also treat the surface with ordinary wall paint). The best way to deal with noise is to close the window. Whether you have a single window or a double window, sealing is the most important thing. The bearing capacity of a barrel is determined by the shortest sawdust, and the sound insulation effect is determined by the weakest link. In addition, it is a simple way to use thick curtains to consume some sound energy, but it is certainly not a very effective way. The above practice is aimed at roadside noise, but it is also effective for other noises. But in general, traffic noise is the most important type of noise, so solving traffic noise will solve other noises. Of course, the noise caused by piling is long-term, but it can only be solved by complaining to the environmental protection bureau and other institutions. After all, the sound intensity of piling is too strong, and general sound insulation measures are difficult to prevent. In fact, it is not necessary for us to set standards for sound insulation and decoration of the audition room in order to prevent short-term noise. At the same time, when buying a house, noise should also be taken into account. Observe the noise environment of the house to be purchased at different times, and determine the degree of influence according to your actual situation. For example, most elderly people go to bed late and get up late, so I will never choose a house near the school or the vegetable market, because I don't like listening to the music of radio exercises and eye exercises from the tweeter, but it doesn't matter to the working class who get up early and leave early, because when the horn rings, my family has already gone to work. In view of the fact that more and more residents are disturbed by noise for a long time, it is difficult to get enough rest, which affects their work efficiency and leads a very uncomfortable life.
Question 4: My home is on the roadside. How can we achieve sound insulation? The house is by the road. What is the main noise outside?
If the wall is not soundproof, the bureau will make soundproof walls, and if the windows are not soundproof, they will make soundproof windows.
Chuangxiang soundproof window
Question 5: How to prevent noise from houses along the highway? At present, there are only these, using sound insulation walls or using the interior design of karaoke rooms. Windows use double glass, I mean single-layer windows use double glass, which is popular in the construction industry at present, and is also used in some high-rise buildings.
Question 6: How to soundproof the houses along the road? This is really difficult, because the foundation is shaking and the house is shaking. Thin walls, poor sound insulation effect.
Generally, you will see isolation zones on both sides of train lanes and viaducts. That kind of material can absorb a certain amount of noise and needs to be erected 2 meters outside the house to be enclosed.
Question 7: How do the doors and windows of roadside houses sound insulation? The main noise source of roadside houses is car noise, and most of the noise comes in through windows.
The landlord only needs to customize special soundproof doors and windows.
Question 8: How can a house near the road solve the problem of sound insulation? In addition to installing sound insulation glass, it is better to install soundproof windows, which can solve this problem. I live in a tall building, close to the road, and I am often awakened by those hateful noises when I sleep at night. Since installing the soundproof window, I can finally rest assured. I found this sound insulation company through a friend's introduction. I suggest you install the soundproof window of this company. The soundproof effect is very good and the service attitude is very good. The name of their company is Shanghai mute soundproof window!
Question 9: The house you just bought is very noisy near the road. How to do sound insulation and noise reduction? Complain with neighbors and ask the property to install a sound barrier. There are many examples of noise-proof wall information network, which are all solved in this way.
Question 10: If the house is bought on the roadside, how can the sound insulation effect be good? How to do sound insulation? I heard that there is a sound absorber, so you can check it online. Double-layer sound insulation glass sound insulation plus multi-layer windows, using plastic steel and installing double-layer curtains. The fabric is also double-layered, with a layer of shading cloth and a thick curtain cloth. In this case, the effect should be better. I hope I can help you.
