The sound of deliberate knocking upstairs will affect the downstairs floors

If the noise from the upper floors penetrates the structure of the building, it may affect several floors below. But the specific impact will vary on a case-by-case basis, and here are some possible scenarios:

1.If the building is poorly insulated, then the noise from the upper floors may affect several floors below. The exact number of layers affected depends on the intensity of the noise and the degree of poor sound insulation. If the soundproofing is poor, then the downstairs floors may be affected.

2.If the structure of the building is open-plan, such as large bays or rooms with no partitions, noise may be more likely to spread to other rooms or floors. In this case, the sound of deliberate banging upstairs may affect several floors below.

3.If the structure of the building is airtight, for example there are good soundproofing materials and partitions, then the impact of noise may be limited. In this case, the sound of deliberate banging upstairs may only affect one floor downstairs or the next room.

In summary, the exact number of floors affected depends on a variety of factors, such as the intensity of the noise, the quality of the sound insulation, and the structure of the building. If you feel affected by the noise, you can try to contact the relevant authorities or professional bodies for help and solutions.

Three floors.

Construction noise is highly penetrating, and noise can pass through the building structure.

Spread to other spaces, especially in a relatively quiet environment at night, the noise is more obvious and the weakening speed is slower, so if there is a bump or slide sound upstairs, it can be heard clearly downstairs.

The floor slabs are now so thin that even the first floor can hear the third floor. Especially in the current high-rise buildings, the steel bars in the cast-in-place structure are all connected together, especially the kind of vibrational noise, which will drive the entire floor and several floors can be heard.

audible.

The ceiling is connected to the roof, when you knock on the ceiling, the sound will spread to the ground upstairs, you can hear it, the solid is the medium of sound propagation, it is recommended not to knock on the ceiling casually.

1. Knocking on the ceiling downstairs and upstairs can be heard Upstairs and downstairs are separated by a layer of boards, the sound can be transmitted through objects, downstairs and upstairs are very close to each other, and all downstairs knocking on the ceiling can be heard upstairs.

2. This depends on how far the interval is, and whether the structure of the house is good or not, the sound insulation effect of a good house is good, and there is no way to say a bad house. Generally, knocking on the wall downstairs, you can hear it upstairs, and you will feel a little bit of shock if you don't hear it, after all, the building is one.

3. Solid is the medium of sound propagation, the ceiling is connected to the roof, and when you knock on the ceiling, the sound will spread to the ground upstairs.

Upstairs ceiling how to do a suspended ceiling:

1. Pre-construction preparation.

Pre-construction preparation is a must for every decoration link. First of all, we need to check whether the overall structure size is consistent with the preset drawings, and whether the equipment piping is installed clearly. Whether the ceiling installation materials and tools are complete.

2. Smallpox base treatment.

Grassroots treatment is the guarantee of the quality of later construction. Before construction, we should clean the top surface of the ceiling so that it can meet the requirements of construction. If there is a problem, we can take immediate remedial action.

3. Ceiling elastic line positioning.

The elastic line is the first step in the construction of the ceiling, and its main role is to mark the ceiling elevation line and keel line, so that you can have a clear understanding of the coverage of the ceiling. The positioning of the keel should be arranged according to the size of the veneer and the position of the keel. When you are arranging the keel grid, try to ensure the uniformity and integrity of the keel grid, so that the ceiling has a more regular decorative effect in the later stage.

This must be heard, because there is a 12-15 cm floor slab between the upstairs and the downstairs, and you knock on the wall in the same room, and the next room will definitely be able to hear it.

This depends on how far the interval is, and whether the structure of the house is good or not, the sound insulation effect of a good house is good, and I can't say if the house is bad. Personally, generally knocking on the wall downstairs, the upstairs can be heard, and if you can't hear it, you will feel a little bit of shock, after all, the building is one.

Hello, you can hear me.

Solid is the medium of sound propagation, the ceiling is connected to the roof, when you knock on the ceiling, the sound will spread to the ground upstairs, it is recommended that you do not knock on the ceiling casually, so as not to affect the normal work and rest of others.

Knocking on the ceiling downstairs can be heard upstairs.

Upstairs and downstairs are separated by a board, sound can be transmitted through objects, downstairs and upstairs are very close to each other, all downstairs knocking on the ceiling can be heard upstairs.

It can be heard, sometimes the whole building can hear it.

People downstairs can hear it, people upstairs basically can't hear it, basically this is the induction is very much, because the night is very quiet, if it rings like this, the whole building may hear the sound, the impact is quite large,

It's easier to hear upstairs downstairs.

Analysis, we first have to look at the daily life of a large number of shouting sound from what position, life our noise is usually ** in the mouth and hands of people, that is, at a height of 1-2 meters from the ground, these sounds are emitted, through the window or floor to the ears of the listeners, we can calculate, usually the current building floor height is about 3 meters, then the sound downstairs to the upstairs into the distance is the height of the floor - the height of the sound source + the height of the human ear. And the distance from the sound upstairs to the downstairs is the height of the sound source + the height of the floor - the height of the human ear. Because the height of the human ear is obviously greater than the height of the sound source, it can be clearly seen that the distance from the downstairs to the upstairs is smaller than that of the upstairs infiltration and delivery downstairs.

Our feelings in life are usually that it is easier to hear the sound of the downstairs downstairs, why is that? In fact, the reason is very simple, our buildings now have sound insulation indicators, that is to say, most of the noise generated by our normal daily life can be absorbed and isolated by the building itself, only the particularly loud sound and the sound of direct knocking on the building are easy to spread out and be heard by neighbors, what is the reason for the particularly loud sound and the sound of directly knocking on the building in our lives? "Phew!

Either move furniture or smash things. Then the height of this sound source is on the floor, which is equal to 0, and the distance from the downstairs is much smaller than that upstairs.
