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.
