The brick wall has good sound insulation effect. Generally, there are many light body walls in the interior. The sound insulation effect of the light wall is far less than that of the load-bearing wall. 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 door and window 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 grooving on the slab wall may also damage the sound insulation effect.
Use thick curtains to reduce noise. 1. The best way to deal with noise is to seal the windows. Whether it is a single-story window or a double-story window, the seal is the most important. The load 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, the 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 linearly transmitted, and most of it can be reflected by 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 and 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 palm pad of the mattress is better than the Simmons with spring.
4, some wall treatment can be used to achieve the sound insulation effect, for example, some houses now use light bricks as the wall, these materials are poorly sealed, if the noise on the roadside is very large, you can rely on the wall of the road It is made of a light steel and paper gypsum board, and the interior is a sandwich of sound-absorbing cotton, which can solve the problem of sound insulation to a large extent.
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.
The solid wood composite door has a strong degree of adhesion and a relatively good sound insulation effect. 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. Need to be reminded that in the decoration process, many people are pursuing the better the wall paint, it is recommended that when choosing the wall paint, do not blindly pursue high-gloss paint, but should choose some paint with a little wrinkle texture after painting, this will absorb Part of the sound.
We have to admit that we are both the most innocent victim of all kinds of noise and the most powerful manufacturer. 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.
The night noise of the bedroom should not exceed 30 decibels. According to Yan Xiang, director of the Architectural Physics Laboratory of Tsinghua University and Dr. Yan Xiang, the acoustics of the building, the noise is no more than 30 decibels. The human body feels comfortable. If the indoor noise reaches 46 decibels or more, it will be serious. Affect people's life, work, and study. However, each person's sensitivity to noise varies, and the tolerance to noise changes with age and physical condition. According to medical experts, long-term low-frequency noise, it is easy to cause a variety of neurosis, such as neurasthenia, insomnia, headache, and even affect the fetus in the belly of pregnant women.
There are many types of noise, and there are four main sources of indoor noise. First, traffic noise, some buildings facing the street, the damage is extremely heavy; second, urban construction noise, building construction site noise is generally above 90 decibels, up to 130 decibels; third is social life and public places noise. Finally, household appliances directly cause indoor noise pollution.
According to Yan Xiang, according to the relevant provisions of the relevant national standards, the night noise of residential bedrooms should not exceed 30 decibels, and no more than 40 decibels during the day. Yan Xiang also hinted that consumers can judge whether the noise of the room is excessive according to the standard when purchasing the property. If the standard exceeds the standard, the sound insulation can be properly performed.
Sound insulation and noise reduction requires architectural acoustics and the wall of the house. For indoor sound insulation, it is only necessary to solve the sealing problem. Since sealing is necessary, it must be started from many aspects, and the ventilation should be paid attention to 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.
It is reported that the sound insulation of professional sound insulation windows ranges from 30 decibels to 40 decibels, which can better solve the noise pollution problem under normal circumstances. For the sound insulation and noise reduction in different situations, it is 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.
It should be noted that professional sound insulation solutions should include several key steps: first, to detect the noise source, and to develop a noise control plan according to the owner's sensitive situation; secondly, select the appropriate sound insulation window or other solution according to the noise situation. Finally, the specific design can be carried out.
