How about soundproofing the room? Do this, and the noise will disappear immediately!

At present, urban noise has become an important part of environmental pollution, which not only interferes with people's normal life and work, but also seriously affects people's physical and mental health. Noise pollution mainly includes industrial noise, social noise and traffic noise. With the rapid expansion of urban motor vehicles, the rapid development of transportation facilities has been stimulated, resulting in the construction of urban expressway, traffic trunk lines and urban railways. These new transportation facilities make it difficult for people to find a quiet place in the city. Therefore, how to solve the problem of noise disturbing people has become a hot spot of concern. Let's take a look at the specific solutions!

Let's start with a wave of "simple and extensive" tricks.

1, wooden furniture has good sound absorption function.

Furniture is the most natural absorption and diffusion body indoors, especially wooden furniture has the best effect. It has the characteristics of porous fiber, which enables it to absorb noise and reduce noise pollution. Different kinds of wood have different sound absorption degrees, and softer wood has better sound absorption effect, such as pine. In addition, when placing, don't put large glass cabinets, metal paintings and lighting furnishings that are too reflective to sound waves. When placing books or CD discs, they should be ups and downs to increase the diffusion effect of the reflecting surface. If the bookcase is placed in front of the wall adjacent to the neighbor's house, it can properly block the sound coming from the neighbor's house.

2. The quality of the door panel determines the sound insulation effect.

Each door has a certain sound insulation effect, but the effect is very different. Whether the door partition is soundproof is not only the sealing performance after the door is closed, but also the quality of the door panel. The sound insulation effect of the door panel mainly depends on the filler in the door core. Generally speaking, the inner core of molded sound-proof door is filled with paper base with honeycomb structure, and the closed air layer formed by it can play a good sound-proof role. Inferior door panels are only roughly cut with cardboard in the hollow, and the sound insulation effect is very poor. In addition, the door with particleboard as the inner core has better sound insulation performance. For solid wood doors and solid wood composite doors, the higher the density and weight of wood itself, the better the sound insulation effect of doors with thick door panels, and the easier it is to reduce noise pollution.

3. Rough walls can reduce noise pollution.

If the wall is rough and too smooth, it is easy to produce echoes indoors, thus increasing the volume of noise. Therefore, you can choose decorative materials with good sound absorption effect such as wallpaper, and you can also use decorative materials such as cultural stones to reduce noise pollution, make the wall rough, refract sound waves many times, and reduce noise. In addition, the wall and ceiling can choose sound insulation materials, such as mineral wool sound-absorbing board. Large units can be installed with a layer of gypsum board to reduce noise. Small huxing households can first separate the walls with unequal geometric patterns of solid wood, and then cover them with cork.

4. Thick fabrics can also reduce noise.

Using cloth to eliminate noise pollution is also a common and effective method. The test shows that the sound absorption effect of suspended and flat fabrics is the same, such as curtains and carpets, and the sound insulation effect of curtains is the most important. In addition, the soft touch of the carpet can not only produce a comfortable and warm feeling, but also eliminate footsteps, which is conducive to people's rest. In the bedroom, choose thick curtain cloth to control light and external noise.

Second, the following are high-energy advanced areas.

1, sound insulation felt

Sound insulation felt is a good room sound insulation material on the market at present. Mainly used with gypsum board, it is used for wall sound insulation and ceiling sound insulation, as well as for sound insulation and damping vibration reduction of pipelines and mechanical equipment. The sound insulation felt is not felt, but the appearance is completely different. The felt is light and soft, and the soundproof felt is thin but heavy.

The soundproof felt is made of tasteless EPDM and more than a dozen organic minerals in a certain proportion. This product is black, environmentally friendly and tasteless. It is a good sound insulation material for low-frequency and high-frequency sounds, and can effectively suppress the spread of various vibrations. The thickness of this material varies from 1mm, 2mm and 3 mm. After testing by the National Building Materials Bureau, the weighted sound insulation Rw is 23dB, 27dB and 30dB respectively, and the material is also very flexible.

2. Polyester fiber sound-absorbing board

It is an ideal indoor sound insulation material. Its raw material is 100% polyester fiber, which has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, easy mosaic, simple construction, good stability, good impact resistance, good independence and high cost performance. There are a variety of colors to choose from, which can meet the needs of different styles and levels of sound absorption decoration. Mainly used in theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, gymnasiums, lecture halls, multi-function halls, hotel lobbies, hospitals, shopping malls, schools, piano rooms, conference rooms, studios, recording studios, KTV private rooms, bars, industrial workshops, computer rooms, family noise reduction and other places with high requirements on acoustic environment and high-grade decoration.

3. Wave peak sound absorption sponge

The indoor sound insulation material of peak sound absorption sponge is a kind of concave-convex wavy sponge formed by special treatment of equipment. Its interior is full of tiny gaps and semi-open structure, which can absorb a large amount of injected acoustic energy, attenuate sound waves, reduce the interference and echo of indoor reflected sound, and improve the purity of sound. The wave-peak sound-absorbing sponge is light, tasteless, high in sound absorption rate, good in heat insulation, flame retardant grade B 1, strong in water retention after soaking, harmless to human body and pollution-free to the environment.

Third, let's talk about those things that are "injected" with sound insulation during decoration.

1, wall top

Eliminate the footsteps overhead!

"Move every time ...", this is definitely not a B-box. The sound of footsteps and moving things upstairs makes people upset and crazy, especially when they fall asleep at night, they are easily awakened by sudden sounds, and it is difficult to fall asleep after waking up. Especially when there is a World Cup match, it is simply "tearing down the house" and it is really difficult to interfere with others. You can't help letting people walk in your own home.

Please be careful not to leave the ceiling empty, it would be a pity. In fact, the solution is very simple, that is, to make a special soundproof ceiling with professional soundproof materials. Of course, you must include the ceiling budget in the house decoration fee. Otherwise, the ceiling can be anywhere from 10,000 to 20,000, and the method of light steel skeleton and mineral fiberboard can be adopted. This is the simplest ceiling treatment and the most economical treatment.

Step 2: Windows

I have a plan to eliminate car noise!

Cars are an indispensable part of people's lives and play an irreplaceable role. However, when many people enjoy the convenience and speed brought by cars, they never thought that the noise of cars has caused many residents to suffer greatly.

At one time, most of the soundproof windows installed at home were ordinary hollow soundproof windows, and their sound insulation effect was far from "blocking" the big wave noise near the elevated and main roads. Nowadays, the appearance of vacuum soundproof window has completely defeated the traditional hollow soundproof window. The sound insulation capacity of hollow soundproof window is 15-22dB, and that of single-layer vacuum soundproof window is more than 45dB. Replacing doors and windows at home with vacuum soundproof windows can effectively isolate 75%-95% noise.

Sound insulation materials: plastic steel window frame, sound insulation glass, imported sealing strip.

Cost increase: thousands of dollars.

Step 3: walls

Leave the peace next door!

The concept of "sound insulation design" seems to be ignored by many architectural designs, but the fundamental solution is to use professional sound insulation materials, such as sound insulation blankets. This material has excellent broadband sound insulation characteristics and high damping, which can effectively isolate all kinds of air transmission. Combined with gypsum board and sound-absorbing cotton, the sound insulation effect is very good. In the wall decoration, it is best to make the wall a little concave and convex, such as using wallpaper, wall covering and other materials to do some decoration, and their noise reduction effect is very good.

Sound insulation materials: sound insulation blanket, thick curtain, sound-absorbing cotton, wallpaper.

Cost increase: less.

4, the ground

Don't let the floor creak!

Now the floor treatment at home is probably marble, tile or wooden floor. In order to reduce the sound reflected by the floor, it is necessary to spread a thick carpet on the floor, so that the sound absorption effect is enough. If you only want to use a small piece of thin carpet, it will only play a decorative role, but it will not have substantial sound absorption effect. There must be textile wholesale markets all over the world. As long as it is that kind of thick carpet and it is wool, you can buy cheaper woven fabrics instead of pure hand-woven fabrics, because it will be much more expensive.

In addition, the cork floor has the function of sound absorption and noise reduction. Because cork has excellent sound transmission characteristics and damping performance, cork floor can not only absorb the sound of stepping on the floor, but also play a sound insulation role on different floors, allowing you to release your personality and dance exaggeratedly without worrying about the visits of neighbors downstairs; Ultra-solid wood flooring (composed of solid wood and laminate flooring materials) can also bring new solid wood hearing, and its new wood fiber mute system can reduce indoor noise by half.

Sound insulation materials: cork floor, wood fiber silent floor, thick carpet.

Cost increase: less.

Step 5: doors

Keep the door quiet!

Doors are often a "main force" to make noise at home. Sometimes, even if you close the door gently, you can still hear heavy sounds. This is because the material of the door is not sound insulation material, which will cause such noise. "bridge opening Mechanical Panel" is a brand-new high-tech door core panel made in Germany. Its unique tubular structure can effectively sound insulation. The air retained in the tubular structure is similar to the principle of vacuum flask and sound insulation glass, and the sound insulation effect can reach 30-44dB.

Sound insulation material: mechanical plate of bridge hole.

Cost increase: less.

6. Pipes

Let the indoor pipes completely lose noise!

Using PVC water pipes, the drainage sound can reach 60-70dB. General method: wrap the pipe and fill it with some sound-absorbing materials. But the effect is very poor, basically can't play any role. The solution to this kind of problem can be sound insulation blanket. The process method is as follows: the soundproof blanket is cut into strips with the width of 100mm, one side is coated with glue, and it is spirally wound on a PVC water pipe as the first layer, then wrapped with sound-absorbing materials, and finally a layer of soundproof blanket is spirally wrapped outside the sound-absorbing. This method can completely solve the pipeline noise.

Construction difficulty: ★★★★★

Sound-proof ceiling and sound-proof wall, it is recommended to use sound-absorbing cotton+gypsum board, the inner surface of gypsum board is glued with sound-proof material, and the gap of keel is filled with some sound-absorbing cotton. Whether it is soundproof ceiling, wall soundproof or pipeline soundproof, it is a modest project for every family. The key to the application of sound insulation materials in sound insulation is to "spread" without leaving gaps, otherwise the effect is not good. Some homes have air conditioners on the walls, and some homes have cabinets from the ground to the top. Sometimes curtain boxes get in the way. These problems must have been arranged by the owner in advance, and some things may have to be removed or discarded for "sound insulation"!
