One: How to deal with the poor sound insulation of the floor?
1, put the carpet
You can also spread a thick carpet on the floor to achieve sound absorption effect. 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.
2. Install soundproof ceiling on the floor of the room.
In addition to the external noise, some voices of the upstairs residents will also bring trouble to our home. Therefore, we can install soundproof ceiling on the floor of the room. Generally, the soundproof ceiling of the floor is made of plastic foam of about 5 cm, which can be directly attached to the ceiling of our room. On the plastic foam board on one side of the ceiling, some irregular holes can be punched. As we all know, this will have a certain sound absorption effect.
3. Install soundproof plywood on the wall of the room.
We can stick a wooden keel of one or two centimeters on the wall, then spread asbestos inside the wooden keel, spread gypsum board outside the wooden keel, and then put putty and paint on the gypsum board, which can also have a good sound insulation effect.
Change the soundproof window. The soundproof window is made of laminated glass. Use several layers. Look at your own budget, vacuum glass is available, but you can't buy it. Because the sealing of vacuum glass is a big problem. Whether vacuum sealing or inert gas is used, the cost is too high. Most of what we can buy is insulating glass, not vacuum glass.
The process of insulating glass is actually very simple. Just put some desiccant in the interlayer to get rid of the fog. Insulated glass is suitable for the middle and low floors without shelter, which can effectively isolate high-frequency noise such as dog barking, square dance divine comedy and big speakers. Noise reduction of 25 to 35 decibels, the sound insulation effect is actually very general.
4, soundproof window
PVB laminated glass is much better. The glue in laminated glass can effectively lose noise and vibration, and can effectively filter low-frequency noise. Suitable for middle and high floors near roads, airports and railway stations. Among them, the sound insulation and damping glue can reduce the noise by 50 decibels, but it is necessary to pay attention to buying the glue in the middle tank and replacing PVB with DEV film, which will greatly reduce the effect and turn yellow in a few years.
In addition, compared with aluminum alloy glass, plastic steel window frame can reduce the noise by 5 to 15 decibels, and sealing casement window can achieve sound insulation effect.
Step 5 choose wooden furniture
In furniture, the sound absorption effect of wooden furniture is there. The porous characteristics of its fibers enable it to absorb noise and reduce noise pollution.
6, the wall texture is rough
Compared with smooth wallpaper or smooth wall, the rough texture of the wall can weaken the role of sound in the transmission process, thus achieving the effect of silence.
Poor sound insulation at home If the poor sound insulation at home affects our life, then we can set up sound insulation materials in different parts of the home, so that the home will become much quieter and the quality of sleep will be higher. In interior decoration, don't forget the key point of sound insulation when choosing materials, especially for indoor doors, the sound insulation effect must be good. Choose indoor materials with good sound insulation effect to make your home much more comfortable.
