Can the floor slab be 20 cm thick to achieve the effect of sound insulation?

The first trick: the wall.

Use wallpaper, or "soft pack" decoration, or cultural stone and other decoration materials to make the surface of the wall rougher, so that the sound waves are refracted many times, so as to reduce the noise. For larger households, a layer of gypsum board can be added to reduce noise. For smaller households, cork can be used to cover the walls, first separating the walls with solid wood in an unequal distance and geometrically, and then covering them with cork.

Noise reduction effect: After the wall is renovated, the noise can be reduced by more than 50 decibels.

Modification notice: Once the wall is remodeled, the indoor area will be relatively reduced.

The second trick: light.

If the color of the ceiling, floor, and wall is too bright, it will interfere with the central nervous system of the human body, make people feel upset, and be particularly sensitive to noise. Therefore, in the selection of various lamps and decorative materials for interior decoration, special attention should be paid to soft light.

The third trick: furniture.

The amount of furniture placed in the home should be moderate, less it is easy to make the sound resonate and resonate in the room, and more is easy to bump into each other. Wood furniture is well insulated, and wood fiber furniture is porous and absorbs noise. Different woods have different levels of sound absorption, and softer woods absorb more sound, such as pine.

Placing a bookcase in front of a wall adjacent to your neighbor's house can block out the sound coming from your neighbor's house.

The fourth trick: cloth art.

The sound-absorbing effect of fabric is well known, so the use of fabric to eliminate noise is also a more common and effective method. Tests have shown that the sound absorption effect and effect of draped and tiled fabrics are the same, such as curtains, carpets, etc., and the sound insulation effect of curtains is the most important.

The fifth trick: glass bricks.

Transparent glass bricks are applied to exterior walls or interior partitions to provide good lighting and a sense of continuity. Glass bricks are low-penetration acoustic elements that can be effectively used in busy streets or homes near factories to block noise distractions. The approximate vacuum state of about atmospheric pressure in the glass can make the glass brick become a better thermal insulation effect than double glazing, and it is the best building material to save energy.

Inquiries about purchasing materials.

To put it simply, the floor slab is a wooden material, the effect of sound insulation is not very good, there is a certain sound absorption effect, it is recommended that it is best to lay a layer of sound insulation material under the floor slab, the most important thing is to seal well, and glue the joints should be glued.

There seems to be a shop in Qingdao that sells soundproofing materials! You can check it out online!

It depends on what kind of material it is.

If it is a traditional material, of course, it is better to have a higher density, and if it is a new type of sound insulation material, 20 cm is wasted.

Summary. It is a cast-in-place floor slab that is better soundproofed than a prefabricated floor slab! Two common approaches:

1. Channel steel or I-beam construction. Under normal circumstances, channel steel is used, but the bending strength of I-beam will be higher, of course, the cost will be higher, and the space occupied by I-beam is also larger. The advantage of channel steel construction is that it is fast, ready to use, and does not need to wait.

The disadvantage is that when people walk on the attic made of channel steel, there will be a certain shaking sound, and the smaller the channel steel specification, the louder the shaking sound. The use of channel steel is a recommended practice. 2. Reinforced cement cast-in-situ.

The practice of reinforced concrete belongs to civil engineering practices, but there are additional conditions, that is, the original wall is required to have a steel plate interface or other reinforcement reinforcement connected with the structural reinforcement, otherwise the weight of reinforced concrete is not a general support or fixing piece can be fixed, and there will be a safety threat. The advantage of reinforced concrete floor slab is that when people walk on it, there is generally no shaking feeling, and there will be no sound (unless the floor slab is very thin), the disadvantage is that the cement floor slab is generally very time-consuming, after pouring, the pure maintenance time will have to be more than one month, plus the previous construction time, there must be 2 months before and after.

Hello, happy to answer your questions.

It is the cast-in-place floor slab that has better sound insulation than the prefabricated Zihuiliang floor slab! There are two common methods: 1. Channel steel or I-beam construction.

Under normal circumstances, channel steel is used, but the bending strength of I-beam will be higher, of course, the cost will be higher, and the space occupied by I-beam is also larger. The advantage of channel steel construction is that it is fast, and the trace is ready to use, and there is no need to wait. The disadvantage is that when people walk on the attic made of channel steel, there will be a certain shaking sound, and the smaller the channel steel specification, the louder the shaking sound.

The use of channel steel is a recommended practice. 2. Reinforced cement cast-in-situ. The practice of reinforced concrete belongs to civil engineering practices, but there are additional conditions, that is, the original wall is required to have a steel plate interface or other reinforcement reinforcement connected with the structural reinforcement, otherwise the weight of reinforced concrete is not a general support or fixing piece can be fixed, and there will be a safety threat.

The advantage of reinforced concrete floor slab is that when people walk around on it, there is generally no sense of shaking, and there will be no sound (unless the floor slab is very thin), the disadvantage is that the cement floor slab is generally very time-consuming, after pouring the blue slowly, the pure maintenance time will have more than one month, plus the previous construction time, there must be 2 months before and after.

1. Put a carpet. It is also possible to lay a thick carpet on the floor to achieve a sound-absorbing effect. If only small pieces of thin carpet were used, it would only have a decorative effect, but no real sound absorption effect.

2. Install soundproof ceilings on the floor of the room. You can install a soundproof ceiling on the floor of the room, and the soundproof ceiling of the general floor is made of plastic foam of about five centimeters, which is directly glued to the ceiling of the room.

On the top of the plastic foam board on the ceiling, you can also pierce some irregular holes, so that you can have a certain sound absorption effect.

3. Install soundproof plywood on the wall of the room. You can make a wooden keel of one to two centimeters on the top of the wall, and then lay asbestos on the inside of the wooden keel, and plasterboard on the outside of the wooden keel.

Then go to the top of the plasterboard to putty.

Brush paint, so that it can also play a good sound insulation effect.

4. Soundproof windows. PVB laminated glass.

The gum can effectively dissipate noise and vibration, can effectively filter low-frequency noise, and is suitable for unobstructed middle and high floors close to roads, airports and railway stations. Among them, the maximum noise reduction of the infusion sound insulation damping glue is 50 decibels, but be careful to buy the middle tank glue, using DEV film instead of PVB, the effect will be greatly reduced, and it will be yellowed in a few years. In addition, the window frame is made of plastic steel windows.

Compared with aluminum alloy glass sound insulation, it can reduce the noise by 5 to 15 decibels, and the window opening method is the best sealing casement window.

way, to achieve the best sound insulation.

5. Choose wooden furniture. Among the furniture, wooden furniture has the best sound absorption. The porosity of its fibers allows it to absorb noise and reduce noise pollution.

6. Rough textured walls. Compared to glossy wallpaper or smooth walls, a rough-textured wall can mute the sound as it propagated.

Sound insulation must see common sense.

If your home is not soundproofed, noise is inevitable. Especially in the frame-cut room, unscrupulous people make loud noises, which will resonate. If the floor and walls are thick, it is estimated that they can be muted, but this is not possible.

The top floor can avoid nearly a third of the noise, if it is a staircase... Unless you're planning to exercise. The top floor is ridged, and there is little chance of leakage. The flat top is worrying, and if the recent rainy season does not miss the year, it should be fine.

1. The floor slab is generally about 15 cm, and the sound insulation effect of the floor is not good. If you don't do sound insulation, the thickness of the floor slab does not play a big role in sound insulation.

2. The floor slab is a kind of separation load-bearing member. The load-bearing part of the floor layer, which divides the house vertically into several layers, and transmits the vertical loads such as people and furniture and the self-weight of the floor slab to the foundation through walls, beams or columns. According to the materials used, it can be divided into several forms, such as wooden floor slabs, brick arch floor slabs, reinforced concrete floor slabs and steel lined floor slabs.

About 15 cm, and a layer of floor level on top can be soundproofed.

This situation is now more common because the floor or wall panels are too thin and the materials used are of low grade. If there is a wooden floor upstairs, it is even more noisy, and this noise is transmitted through two ways: air and resonance. Consider using high-density panels or specialized acoustic panels to block out airborne noise, and vibration isolation to block solid-propagated resonances.

That is, the roof is first isolated from vibration, and high-density panels can be used for sound insulation. The principle of construction of the walls is the same. At the same time, the construction method is also important.

If it is a floor, it will be a floating building, and the principle is the same as vibration isolation and then sound insulation.

The question is both simple and complex. It mainly depends on whether you are willing to invest. The sound insulation of buildings is a construction problem, such as poor sound insulation of walls and floors. If you want to improve it when you renovate, it will cost you a lot of money.

The first step is to check the heating, water pipes and other wall pipes, and seal them if there is an air attack.

The second step is to check the bathroom vents, which are generally the weak links of sound insulation, and it is best to use an exhaust fan (there are shutters that are cheaper), and it is recommended to use wooden doors in the bathroom.

Clause. Third, this is expensive, and the sound insulation of the house is so poor that it is unbearable. Wooden keel (2-3cm) bulky board filling 2 3cm, MDF wall full package.

It's extravagant, right, I'm in the north, and I don't know how it will work after completion, so it should be good. ）
