① Outside the window: the sound of traffic, the thunder of the construction site, shouts, the music of square dance, etc. Neighbors: the crying of neighbors' children, the sound of neighbors walking on the roof, etc. ③ In the room: the sound of relatives watching TV in the living room, the sound of water running in the bathroom, the sound of electrical equipment running, etc. It is not difficult to see that the main factors that endanger sound insulation are the quality of doors and windows, the thickness of walls and protective layers, sewer pipes and electrical equipment. We can start from these aspects and make a sound insulation design plan purposefully. Let's take a look at these four core sound insulation methods with Xiao Ai!
First, the quality of doors and windows Aluminum alloy doors and windows are the first line of defense for indoor sound insulation, which can isolate most indoor and outdoor noises. Therefore, we also need to pay attention to these two aspects when purchasing: material and sealing. Indoor wooden doors generally use solid wood doors, but the filling materials of the internal structure of solid wood doors are quite different, such as solid wood boards, honeycomb cardboard, high-density boards and bridge opening mechanical boards.
If you want good sound insulation, we recommend that you prefer solid wood doors filled with solid wood boards, which can be bought for one or two thousand, with high cost performance. Most windows use aluminum alloy window frames, and the broken bridge aluminum window has the best heat insulation and sound insulation effect. The choice of laminated glass is also very important for window sound insulation. It is recommended to use two layers of toughened insulating glass, the thickness of which is basically 5mm, or 6-8mm thick glass. If you want to have better sound insulation and heat preservation effect, you can also choose double-layer laminated glass or three-layer insulating glass. The effect of three layers is undoubtedly better than that of two layers.
It is often said that sealing is another key factor for sound insulation of doors and windows. What we are afraid of is the good goods bought at a high price. In the end, because of improper installation, it will leak air and water without sound insulation, which is so annoying ... Therefore, when installing doors and windows, we must do a good job of completion acceptance to prevent cracks from happening around us. The application of sound insulation strips can improve the sound insulation effect of doors and windows, so that the sound insulation effect is twice the result with half the effort ~ I suggest that you use cotton-wrapped sound insulation strips, which is the toughness of this material. Although we can't change the structural materials of the house, we can improve the sound insulation effect of the wall through design and decoration.
For the noise of the ceiling, when decorating the ceiling, you can add two kinds of sound insulation materials: silencing cotton and high-density foam board. They can reasonably and effectively improve the sound insulation effect, reduce the noise of neighbors on the roof, and are not easy to put pressure on the renovated ceiling. In the basic room type, the vast majority of houses are separated by a wall between two rooms. If there is no sound insulation effect, both sides can hear each other's heart-to-heart conversation. So when we solve the problem of wall sound insulation, we can add sound insulation felt. This kind of raw material can reasonably block the spread of sound and is not easy to damage the decorative design effect of the wall.
