Individuals can learn something from this news.
Recently, many readers called and said that living at home in the city or along the main traffic road like the Third Ring Road was deeply affected by traffic noise, so they couldn't sleep well at night and were listless during the day. I hope the reporter can investigate and find some good ways to reduce the noise at home. Subsequently, the reporter found that the residents of these houses were more or less affected by different degrees of noise in some communities next to the main roads such as the Second Ring Road and the Third Ring Road. So, how to prevent noise when living in downtown?
Measure 1: closed noise reduction windows are used for doors and windows.
Doors, windows, corridors, terraces and other parts are the direct incoming channels of noise. After these parts are handled, the first line of defense against noise and noise reduction is constructed.
The best way to deal with noise is to close the window tightly. Whether you have a single window or a double window, sealing is the most important thing. The sound insulation effect is determined by the weakest link. To some extent, doors and windows are the weak link of noise reduction. Therefore, it is an effective scheme to use plastic steel window as sealing means. For households that have adopted aluminum alloy, ensure that the sealing strip of aluminum alloy frame is intact. If the economy permits, noise reduction windows can also be installed. The glass of the noise-reducing window is similar to double-layer glass, except that the two pieces of glass on the window are not parallel, but at a certain angle, which is conducive to reducing noise. In addition, the noise reduction window is more tightly closed than ordinary windows, so the noise reduction effect is very good.
In order to fully reduce the noise, it is necessary to deal with it from outside and close the balcony. If there are balconies and terraces outside the house, it is best to close them. According to calculation, if the balcony is 3m long, the guardrail is 1m high and overhanging 1m, the noise can be effectively reduced by about 6 decibels after closure. Finally, by using thick curtains, some sound energy can be consumed, which is also a relatively simple method and can be used as the final supplement of doors and windows.
The second trick:
Rough interior wall materials are used for interior wall treatment.
The wall is too smooth, any sound will echo, which will increase the noise. Therefore, when dealing with external walls and internal walls, you can choose some uneven ways to decorate the facade. Generally speaking, the facade of the house is handled by the developer in a unified way, and the owner has no right to handle it separately in the later period. Therefore, developers should consider noise reduction when planning and designing, and use rough exterior wall materials when building the facade of the house. Because the reflection and refraction of sound waves are somewhat similar to light, hitting a smooth plane, such as a ceramic tile, will make the reflected energy more concentrated and directional. If hitting a rough plane, it will spread and have much less impact on people.
It is more convenient to treat the interior wall with soft decoration such as wallpaper, or with decorative materials such as cultural stones. Cultural stone is a new material that has appeared in recent years. It is used for decoration and embellishment of some sketches and ancient pavilions at home or outdoors, and it is beautiful and generous after decoration. Make the wall as rough as possible, so that sound waves can be refracted many times, thus reducing noise. Large units can be installed with a layer of gypsum board to reduce noise. Small families can cover their walls with cork. Firstly, the wall is geometrically divided with solid wood, and then covered with cork.
Finally, you can hang some pictures or calligraphy works on the inner wall according to your own preferences, which can beautify the house and reduce noise.
The third measure:
Processing suspended ceiling, installing sound-absorbing suspended ceiling to reduce noise.
At present, traffic noise is the main source of urban low-frequency noise. It can attack and penetrate walls from a distance. Even if your home is a few hundred meters away from the road, it is difficult to guarantee that you will not be disturbed by it. Low-frequency noise can pass through the wall. Even if the owner closes the doors and windows, the feeling of low-frequency sound reduction is endless. Mr. Jiang, who lives in the Third Ring Road in the west of the city, is 0/50 meters away from the Third Ring Road/KLOC-,but the reporter also felt a dull sound in his home, which experts call "low-frequency noise". We can't use the method of "isolation" to deal with low-frequency noise. The most effective means is to install a "sound-absorbing ceiling", which can reduce the low-frequency noise from 80 decibels outdoors to less than 30 decibels indoors, which means that even if you live next to the main traffic road, you can have a villa-like quiet environment.
The fourth measure:
Chen Qiao furniture adopts wooden furniture and fabric sofa.
If the ceiling, floor and walls in the room are too bright, it will interfere with the central nervous system of the human body, making people feel irritable and particularly sensitive to noise. Therefore, when choosing various lamps and decorative materials for interior decoration, special attention should be paid to soft light. So when decorating indoors, try to use the same color.
The amount of furniture placed at home should be moderate. Without it, it is easy to make the sound ring in the room. With it, it is easy to bump into the west. Choosing wood furniture will get a good sound insulation effect. Wood fiber furniture is porous and can absorb noise. Different kinds of wood have different sound absorption degrees, and softer wood absorbs more sound, such as pine. Putting the bookcase in front of the wall adjacent to the neighbor's house can properly block the voice of the neighbor's house. In addition, the experiment shows that the suspended and tiled textiles have good sound absorption effect, so as long as you use fabric products indoors, you can also play a certain sound absorption effect. Among many fabric products, curtains have the best sound attenuation effect, followed by fiber products such as tapestries on the wall.
Experts from Chengdu Environmental Protection Bureau said that traffic noise prevention is a systematic project. In order to treat both the symptoms and root causes, systematic engineering must be adopted for comprehensive treatment, and synchronous control measures should be taken in the stage of urban planning and construction. It is necessary to install sound insulation walls from the original sources such as traffic roads to reduce the speed and noise of cars. When developers develop houses, they require sound-absorbing and sound-insulating materials for external walls, and then the owners adopt the above practical methods for indoor decoration in the later period. Only through such a set of perfect and systematic noise prevention and reduction measures, and each link is handled well, then even if the house is built in a humanized environment, we will enjoy a brand-new "quiet" living space.
