How to solve the problem of poor sound insulation in buildings

Treatment of houses without sound insulation: installing a ceiling with sound insulation effect at the top of the house can reduce the impact from upstairs; Installing floor or carpet on the ground can make your daily life not affect the downstairs residents; Installing sound insulation materials on the wall can appropriately reduce the influence of neighbors on their homes; By installing double glazing, outdoor noise can be reduced.

Wall sound insulation material: sound insulation board: this kind of material is common, widely used and has excellent sound insulation effect. It is usually used for wall construction. In order to ensure its sound insulation effect, it is necessary to carefully check whether the test report is qualified before buying, so as to avoid buying inferior sound insulation boards and achieving the expected sound insulation effect.

Damping pad: mainly made of olefin damping pad foaming. It has unique structure, special technology and good noise reduction effect, and can effectively control and buffer the spread of sound. It is one of the most widely used ground sound insulation materials.

Sound-absorbing cotton: This material is waterproof, moisture-proof, breathable, sound-absorbing and noise-reducing, and it is convenient to construct, so it is also widely used in ktv, hotels, dance halls, recording studios and other places. However, this kind of material has poor flame retardancy and weak fire prevention, and once a fire breaks out, it is difficult to stop the fire from spreading.

Doors and windows are the main way for outdoor noise to enter the room. The gap and material between the window and the door will affect the noise, so it is a better method to use plastic steel as sealing strip. On the other hand, there are windows and doors. At present, the better soundproof windows are all composed of three layers of glass with different thicknesses. You can replace the old glass decorative materials or sealing strips to achieve the purpose of noise reduction.

Wall is the main component of the building, occupying four sides of the building, and it is the main source of noise transmission. Due to the large area and variety of indoor wall decoration materials, noise enters through the wall, which makes us unavoidable. Generally, the walls of buildings will be made of concrete and solid bricks, which can better isolate noise.

For some hollow walls or partitions, it will naturally have a greater impact. We can tear down the original wall and directly replace it with a soundproof wall if conditions permit. If conditions do not allow, you can add another layer of sound insulation wall outside the original wall. We can replace the indoor decorative wallpaper with thick and uneven surface during the decoration design or later.
