I heard the sound of knocking all the time in the middle of the night is why the windowsill

There are many reasons that could cause you to hear a window knock in the middle of the night, and here are some possible reasons:

1.Thermal expansion and contraction - The sound of thermal expansion and contraction of the wall and concrete, or the imbalance of forces due to temperature changes.

2.Reasons for the window material - The reason for the window material, it can also cause the window to make a clattering sound when the force is uneven.

3.Windows are not properly installed - If the windows are not installed properly, it can also cause the windows to be stressed unevenly, resulting in a clanging sound.

4.It could be a rat grinding its paws on a window – A rat may grind its paws on a window, making a knock-knock sound.

5.Wind Sounds - Wind sounds can also cause windows to make a knocking sound. Especially in high-rise buildings, the higher the wind speed, the louder the sound.

6.Noise from buildings - Noise from buildings, such as mechanical vibrations, equipment operation, etc., can also cause windows to rattle.

It is necessary to analyze the situation according to the specific situation, find out the ** of the sound, and take corresponding measures to solve the problem.

Because when the wind blows, there is power, the windows vibrate, and the sound is produced by the vibration. Just set a resistance where the wind is blowing.

1. Under normal circumstances, the wind blows the window and the sound is caused by the gap in the window, so you can check whether the window has been closed tightly. If the window is closed tightly, there will be such a sound, be sure to check whether there is a gap in the window, the tightness is not good, if there is a gap, you can use a sealing strip to plug the gap, so that there will be no sound.

2. When the wind is particularly strong, there will be a little noise when the wind beats on the window. Since we didn't have a way to control the wind, we were able to install some soundproofing materials. Install some heavy curtains on the windows, because the heavy fabric has a certain soundproof effect, so that the sound of the window can not be heard.

3. It may be the reason for the window material, and there are also some older window materials, which are easier to shake and make noise when the golden wind blows.

The sound of thermal expansion and contraction of building materials may also be the sound of water pipes laid in the wall, because it is separated by the wall, it is not like the sound of thermal expansion and contraction, and it will be a dull sound

Landlord: The situation of my house is the same as yours, my house has been built for more than three years, and there is a sound of vibration in the wall late at night, and the sound is loud and sometimes small, and it has been ringing for three months, and it started to ring in August 2019, and now I don't know what to do, can anyone explain it from a scientific point of view? Thank you.

Yes, it's just the fucking bad guy smashing the wall with a hammer, this thing can't be solved by ordinary people, you have to find a miracle doctor to see v.

Mr. Feng Shui watched the time, and so did the explosion of my house. It's not good that the house doesn't ring.

Whether it's the sound from upstairs or something else, pay attention to yourself.

My house is like this now, ask the witch and you will know, really.

There is a lot of noise upstairs for the following reasons:

1. Sounds caused by cracking or other changes in the building itself due to air flow or temperature changes. An incomplete fungus that mainly corrodes industrial materials and cement, and is better to grow on porous surfaces and feed on the minerals in cement.

2. Generally, the ceiling is supported by two layers of fine steel bars, in fact, the steel bars are not straight and are stuck in the cement, and the flow and weight of the cement slurry may have upward or left and right stress accumulation.

Upstairs noise

According to the statistics of the China Property Management Association, the number of neighborhood noise complaints is increasing year by year, accounting for more than 40% of the complaints of property owners, of which the upstairs noise accounts for the highest proportion, accounting for more than 80% of the noise complaints. Factors such as thin floor slabs, high population density, and lightweight walls of high-rise residential buildings are the objective reasons for poor sound insulation of houses.

Poor living habits, irregular work and rest schedules, improper child discipline and personal qualities are the direct causes of noise problems in the neighborhood. When dealing with the problem of noise in the neighbourhood, the first consideration is communication, but the noise occurs in our own homes and is not directly felt by the residents upstairs, so the noise communication effect is generally not satisfactory.

With the help of a third party such as a property management company and a community neighborhood committee, mediation is usually adopted, but mediation is often fruitless because the noise maker lacks a sense of noise. The bright chain of alarm processing is the last resort, but in actual implementation, it is difficult to collect evidence of neighborhood noise and imperfect laws and regulations, which makes it very difficult for the police to handle the case.

If you're a materialist, it's the sound next door, transmitted to your home. If you believe that anything is possible, it can be considered a paranormal phenomenon. No matter what the situation is, it has little to do with you, and sleeping peacefully is king.

The things inside the wall are cement, water pipes, steel bars, and wires, and the cold shrinkage of the hot tent has been eliminated, so this is the only logical solution.

I have it at home, and it's so noisy that I can't sleep, and I'm almost annoyed to death!!

One is artificial, or walking around or doing other tapping.

The second is caused by family-raised animals.

The third is caused by the water pipe, due to the unstable pressure, when there is a nozzle waterproof, it is easy to cause the pipe to vibrate and cause sound.
