As we all know, the city is awkward and noisy, especially in the crowds living in the downtown area, home noise has become a big problem. For indoor sound insulation, it is only to solve the sealing problem, and since it is necessary to seal, it must start from many aspects, and also pay attention to ventilation while sealing.
First, the brick wall has good sound insulation effect
Generally, there are many light-weight walls in the interior, and the sound insulation effect of the light-weight walls is far less than that of the load-bearing walls. In terms of walls, brick walls have the best sound insulation, followed by reinforced concrete cast walls, partition walls and plaster walls. The load-bearing wall with internal and external insulation layers will be treated with sound insulation, so the sound insulation effect is also good.
In addition, the material of the doors and windows is also an important part of the sound insulation effect. The single-layer glass that was originally widely used has the worst sound insulation effect. Some irregular constructions such as savage operations such as squeezing and slotting on the slab wall may also damage the sound insulation effect.
Second, the use of thick curtains can reduce noise
1. The best way to deal with noise is to seal the window. Whether it is a single-story window or a double-story window, the seal is the most important.
The carrying capacity of the barrel is determined by the shortest piece of wood, and the sound insulation effect is determined by the weakest link.
From the current state of the art, the use of plastic steel windows as a means of sealing is the most effective decoration. For users who have already used aluminum alloys, it should be ensured that the aluminum alloy frame seals are intact. Relatively speaking, the sealing of aluminum alloy windows is worse than that of plastic steel windows.
2, sound insulation is not to say that it is sealed, but also depends on the sealing performance.
The use of insulating glass in plastic-steel windows is a very effective method, because the pollution of noise is often the high-pitched part, while the high-pitched sound is transmitted in a straight line, and most of the reflection can be made by using glass, and the insulating glass can be partially consumed without reflection. Exhausted.
It is also a simpler way to use part of the sound energy by using thick curtains, but it is not a very effective method.
3. For the middle and low bass generated by vibration friction, carpet or sound-absorbing cotton can be used to reduce their influence on the room.
Adding a rubber pad to the foot of the bed can also alleviate a certain sense of vibration. At the same time, the mattress is better than the spring mattress.
4, some wall treatment can be used to achieve the sound insulation effect.
For sound insulation, you can put a layer of rubber and plastic board on the wall, then put a layer of rubber and plastic board in the middle of the keel, and make the wall surface uneven. This method has the best sound insulation effect, but the indoor space will change. small. For example, some houses now use light bricks as walls. These materials have poor sealing. If the noise on the roadside is very large, you can make a light steel and paper gypsum board on the wall of the road. The interior is sound-absorbing. The interlayer of cotton can solve the problem of sound insulation to a large extent.
Third, the solid wood composite door has a strong degree of adhesion and sound insulation effect is relatively good.
The thickness of the door is preferably 42 mm or more, and the thinner the sound, the worse the sound insulation effect. The sliding door is not as soundproof as the swing door. Remember to use a sealing strip in the groove between the door and the door frame. In addition, in the ceiling of the kitchen and bathroom, the soundproof effect of the waterproof gypsum board is much better than that of the aluminum gusset. Therefore, when the sound quality of the house is generally poor, how to get a quiet and comfortable home environment in the noisy season is particularly important.
Fourth, sound insulation and noise reduction requires architectural acoustics and housing wall coordination
For indoor sound insulation, it is only to solve the sealing problem, and since it is necessary to seal, it must start from many aspects, and also pay attention to ventilation while sealing. It should be said that indoor sound insulation should be a systematic project, and the choice of doors and windows is only one part of it. For the sound insulation and noise reduction in different situations, it is also necessary to cooperate with the building acoustics and the wall of the house. If only relying on the sound insulation window, it will not solve the problem. For the sound transmission of pipes, it can be treated with sound absorbing materials; for the household walls and the sound of the floor slabs, there are also professional sound insulation methods such as paving acoustic boards.
