If there is a lot of noise upstairs, you can hear it every four or five floors, and some of it may spread throughout the corridor
The first place to transmit noise is the floor slab of the building.
At present, the floor slabs of the buildings are not very thick, most of them are about 120mm thick.
Therefore, it is difficult to isolate noise with such thin floor slabs. When there's noise upstairs, the noise is transmitted downstairs through these slabs.
The second part of the noise transmission is the wall. Due to the fact that at this stage of the building, in order to reduce its own weight, many partition walls in the interior are made very thin.
At this stage, the thinnest wall even reaches 100mm. Then this kind of very thin wall must have a very poor sound insulation effect, so when there is noise next door, it will be transmitted along the wall to our room.

Contemporary floor slabs may not be as soundproofed as they are desirable and may result in both upstairs and downstairs noises being heard. Among them, the thickness of the floor slab of the building, the sound insulation performance of the block partition wall and the sound insulation performance of the external windows are all important factors affecting the sound insulation effect.
Poor design of the thickness and size of the floor slabs, as well as the improper use of materials, can lead to poor sound insulation of the floor slabs. For example, if the floor slab is too thin, the bay is too large, or if you use soft shock-absorbing pads, it will be easy to hear sounds upstairs and downstairs.
The acoustic performance of the block partition wall is also a key factor. If a short-limb shear wall structure is used, and aerated concrete block partition walls are used for indoor segmentation, the sound insulation performance of these wall materials may not be sufficient to prevent the propagation of sound.
In addition, the soundproofing of exterior windows is also crucial. If the windows are not soundproofed well, it will cause outside noise to enter the room.
In general, the soundproofing of contemporary floor slabs may be compromised, but whether the upstairs and downstairs can be heard may depend on the design and construction. If you have questions about the soundproofing of your building, it is advisable to consult a professional building soundproofing consultant or have your building soundproofed test.

Can be heard. If you sing loudly in the middle of the night, you can hear it upstairs and downstairs, and the sound is circuitous and can spread through the cracks in doors and windows. The sound does not spread in one direction, but spreads in all directions, the doors and windows are not tightly sealed, and loud singing can be heard, and in today's newly built buildings, the floors are low, the floor slabs and partition walls are too thin, and the sound will even spread everywhere through vibration.

The floor slab is not soundproofed, and the sound insulation and shock absorption pad can be installed to greatly reduce the noise. Sound insulation and shock absorption pads can be used together with other sound insulation materials, the combination of the two can not only improve the effect of sound insulation and noise reduction, but also have a good coordination and decoration, we can reasonably match according to the environment during construction. >>>More
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. >>>More
