With the foam pad, can you still hear downstairs? It is covered with foam floor mats. I can hardly hear it downstairs. If the situation is not very serious, please communicate with your neighbors upstairs and downstairs first and pay attention. If the situation is serious, we can only start with window decoration. If there is no sound insulation layer, please use insulating glass with good sound insulation effect instead. Because of the quality problems of the house, we can only start with the ceiling, walls and floors, fix the keel first, and then add sound-absorbing cotton.
Sound insulation felt: made of elastic materials such as rubber, it has high density, is environment-friendly, does not emit pungent smell after use, can effectively isolate high-frequency and low-frequency noise, and inhibit the spread of sound vibration, and is usually used for roof sound insulation.
Acoustic board: It can isolate noise above 30dB, and has good waterproof and heat resistance and long service life. However, because there are many similar products on the market, the quality varies greatly, so you must pay attention to the quality inspection report when buying. Sound insulation cotton: it is a kind of sponge made by special technology. Because there are many small gaps in it, the sound absorption effect is good, which can isolate external noise and reduce the reverberation of indoor reflected sound. Easy to use and harmless to human body. ?
Afraid of affecting the sound insulation downstairs 1. Carpet carpet can be placed on the floor of the house. The short blanket is not only decorative, but also comfortable to step on. The key is that they can also absorb sound. But the blanket should be big enough, and too small a blanket will not have this sound insulation effect.
Install a soundproof ceiling on the floor of the room. We can make noise downstairs, but the noise upstairs can't be ignored. Installing a soundproof ceiling can reduce noise. Open about 5cm of plastic, or stick it directly on the ceiling, drill some irregular holes, and the sound absorption effect is also very good.
3. Install sound-proof plywood on the wall of the room In recent years, many families have installed sound-proof plywood. If the economy is enough, you can buy insulating glass according to its decoration budget. This material has the best sound insulation effect. The same is true for soundproof windows, which can reduce the noise by 50 decibels. The casement window is selected as the window opening mode to obtain the best noise reduction effect.
4. Choosing wooden furniture Wood furniture is superior to other materials in sound absorption. The main reason is that wood is made of porous fibers. This function enables him to absorb noise and reduce noise transmission.
5. Rough texture walls Rough walls are quieter than smooth walls, and rough walls can reduce the spread of sound to some extent.
The upper and lower floors are not soundproof. If your own floor is enough, you can install a ceiling on the ceiling, which can not only prevent the noise of users upstairs, but also make the room more beautiful. In addition, you can also use a soundproof pad, which is mainly used to isolate the noise of neighbors and users downstairs.
