Why is the roof of my house ringing, ask the master 20

That's because when building a house; The wood is not too dry. Over time, the wood is constantly drawing moisture; The process of coming out will ring; When it rains, it's too humid, so it's not as loud. Don't be too superstitious, the so-called solitary soil is deceiving, don't believe it.

We have a superstitious way of burning paper in the corners of the house and saying goodbye.

Believe in science. Nothing can be explained by scientific evidence.

I've seen a program broadcast in the science column, which is to say that there is a family underground, and there are always voices for a few months every year, sometimes it sounds like crying, sometimes it sounds like the sound of running water, anyway, it is also a lot of uproar, and I also ask Mr. Feng Shui to watch it, everything has been done, and I still haven't found the reason. Later, many scientists went to see and check, but they didn't find out. In the end, an expert in geology went to find out, saying that there was an underground river under his house, which was connected to a river above his house, and that every year in the rainy season, there would be more water in the upper river, and it would flow along the river under his house.

That's probably what it means, I don't make it very clear, anyway, these are not principles that ordinary people can discover.

I want to tell you so much, don't believe in those gods and ghosts, has anyone really seen it in this world, this is just a guess in people's own hearts.

It's too scary to move, some things are unexplained by common sense.

It shouldn't be an accident, and there are many reasons why the roof rings:

First, after studying middle school physics, we all know that objects have their natural frequencies.

However, during the day, the sound is noisy, and there are many sound waves or other vibrations, some of which are the same as their frequencies and some of which are different, so that resonance occurs (resonance is the amplitude of an external frequency close to the natural frequency of an object.

The phenomenon of strengthening), forced vibration (the vibration of an object under the action of an external force, including sound), etc. But due to the noise during the day, it affects our sense of hearing At night, most of the people stop their activities and are quiet, while the sound waves are still there, and due to the frequency of the object, the frequency of the sound is different, the object has a weak motion (the movement of the earth can also be considered, gravitational force.

and so on), there is friction between objects, there is frequency, there are very small decibels.

People may not be able to hear the sound, and we can't hear it during the day, but many objects emit small decibels of sound accumulation, and at night it is very quiet, so it may be heard

Second, the wooden furniture is wet due to moisture in the air or other reasons, but the furniture is dry, and it may make a sound, and at night, it will be heard again

Thirdly, solids such as the earth and the floor are good mediums for the propagation of sound waves (the medium of propagating waves), and sounds from other places are heard

Fourth, I think it should be caused by dryness, and there is a phenomenon of cracking, not necessarily the roof, such as the ceiling.

Wooden materials, doors and windows may make sounds, and if the quality of the house is not good or the decoration materials do not match the building materials, the walls will also crack.

Hello, glad to answer for you. There is a sound on the roof of the pro is like this1There are cat-like animal activities in the house that make sounds2

There are gaps between the building cement materials, and there is a temperature difference between the day and night, which leads to the sound of thermal expansion and cold contraction, and the effect of thermal expansion and cold contraction of cement materials is actually hydration in the final analysis. Hydration is a chemical reaction, which makes the various ingredients of concrete closely combine after the reaction to meet the requirements of strong brother frankness. Theoretically, the wetter the place, the longer the time, the higher the strength of the concrete.

Another role is to play a role in heat dissipation, when the concrete is hydrated, the internal high temperature can reach more than 60 degrees, the ordinary thermometer can instantly, the water can take away the heat emitted by the concrete surface through evaporation, and the excessive heat of hydration will lead to cracks inside the concrete, I hope mine can help you! Do you have any other questions?

How many years will this sound on the roof last? Is there a way to fix it?

Do you often have this kind of noise here? Kiss.

I can't sleep well at night.

Is it a self-built house? Kiss.

6th floor, resettlement house.

Is there anyone living upstairs on your side? Kiss.

Hello dear! 1.There are two reasons why the roof of a rural bungalow always rings, one is that there are small animals on the roof, and the other is caused by the natural phenomenon of thermal expansion and cold contraction.

The solution to the renovation is to lay tiles and build more floors. 2.I believe that many people who have lived in the countryside have such an experience, that is, when sleeping at night, they always feel that something is jumping upstairs, and the sound is not loud, but it is enough to affect a person's sleep quality.

When I was a child, I probably watched too many ghost stories about Shouzhou, and wondered if those things were unclean. But when I grew up, I was exposed to a lot of science. There is a good explanation for these phenomena, that is, the reason for this phenomenon is, on the one hand, because the roofs of rural bungalows are prone to small animals on them.

In the countryside, it was originally a remote mountain village area, and the original geographical location determined that there would be more animals around the house. In this way, the small animals can jump on the roof and run around at night, making people sleepless. 3.

It's not that I can't understand the implications. Another reason is because of the phenomenon of thermal expansion and cold contraction. One thing that many people may not notice is the fact that sounds are heard more often at night in the summer than in the winter.

I live on the top floor.

To solve this problem, it is necessary to transform the knowledge of the world through Kemo. On the one hand, reducing the sound is to reduce the running of small animals, and if the house is built relatively high, this will effectively reduce the chance of small animals climbing to the roof. Another aspect is that the blind limbs need to be added to the bricks, so that the ventilation can be maintained so that the house is not fully heated.

Starting from these two halls, it will be easier to solve the problem of hearing sound when you sleep at night.

Probably. This is based on the material of construction, aging, or the movement of animals causing noise, the solution: add bricks and tiles to reduce the movement of animals.

First of all, there are many equipment on the top floor of the building, for example, the elevator elevator is generally built on the top floor, and the tap water pump may also be on the top floor.

In addition, there are some rain pipes, or some chimneys, and some solar water heaters, etc., which will be placed on the top floor, so sometimes the chimney will fall down or some water pipes will make a sound.

The top floor is close to the floor slab, and there are steel bars and concrete in the floor slab, and there may be a collision sound, which can be heard like a knocking sound, and it may also be caused by the aging of some parts on the top floor, or because the top floor is under construction. Penthouse has certain advantages, but it also has disadvantages, the view is relatively wide, but it is also prone to water leakage.

We suggest that when buying a high-rise building, it is best not to buy the top floor, first of all, the waterproof work on the top floor may not be particularly good, then it will leak after a long time, and secondly, a lot of equipment will be on the top floor, which will make a little noise.

The next time you ask a question, can you be more detailed? Your sentence with no beginning or end makes it difficult for me to answer. I don't know if you're talking about an old house or a new house, and I don't know what the situation is like on your site. I'll tell you all the reasons why I think it's possible!

One: New house.

The roof of the new house generally does not make a sound, after all, the current houses are made of reinforced concrete, even if it is a mouse, there is no way to make a rat nest in it, so how can there be a sound? Could it be that you heard it wrong, or that it was a noise from somewhere else?

Of course, it does not mean that there is no sound in the complete new house, some half a bucket of water master to you when the decoration, not done, may be buried water pipes, or bad wiring, resulting in the sound, it is recommended that you see when you built the house did not ask the master for the water and electricity circuit diagram at home, if there is, take it out and take a look, check everywhere. (Note: Some houses have buried water and electricity underground, and some have buried roofs.)

If there is nothing wrong with it, burn incense and worship the Buddha! Although this is a feudal superstitious idea, most people nowadays don't believe it, including myself. But sometimes it seems that I have to believe it, in short, I want to have peace of mind!

When my house was built, I also heard a strange "click" from the door day and night. But every time I opened the door, no one ......It's a little scary, but then I went to call the letter girl or Mr. Feng Shui to come and see, and I did a Dharma service or something, and then I don't know how, it's really gone!

Two: Old house.

In the past, the roof of some old houses was tiled, many people may not have seen it, there is still that kind of house in our village, whether it is windy or rainy or sunny, as long as something falls on the tiles, there will be a sound, this is very normal, there is no problem. After all, the tiles are relatively light, even if it is a bird, or if it rains, there will be a sound, so don't worry about this.

And whether the old house is a stone roof or a tile roof, there will be mice on it to make a nest, usually there is a sound is really normal, don't worry, it's not a big problem. However, I would recommend that if the family lives in an old-fashioned tiled house or a stone house, it is better to move out. That kind of house has abnormal noise, or it may be in disrepair and has the possibility of collapse.

There is an abnormal noise in the house, which is said to be big or small. I don't know what the situation is if you don't see the roof of your house, so it is recommended that you check it yourself first to see if there is a water leak somewhere, or if the circuit is in poor contact, or if it is in disrepair. If you can't find out the reason and you're scared, find a way to live in a different place!

To be honest, I've been thinking about this for a long time, but I have a result.

After studying middle school physics, we all know that objects have their natural frequencies, but in the daytime, the sound is noisy, there are many sound waves or other vibrations, some of which are the same as their frequencies, and some are different, so there will be resonance (resonance is a phenomenon in which the external frequency is close to the natural frequency of the object, and the amplitude is strengthened), forced vibration (the vibration of the object under the action of external forces, including sound), etc.

However, due to the noisy sound during the day, it affects our hearing. At night, most of the people have stopped their activities, quiet, and the sound waves still exist, due to the frequency of the object, the frequency of the sound is different, the object has a weak movement (you can also consider the movement of the earth, gravitational force and other factors), there is friction between the objects, there is a frequency, there is a very small decibel sound, people may not be able to hear, in addition to the daytime sound mix, we can not hear it during the day, but many objects emit small decibel sound accumulation is large, and the night is very quiet, so it may be heard.

The roof in the house often thinks whether there is moisture in it or the ceiling is not done well and there are gaps, and it should be checked in time to take a look.

I think it's the roof that is making a noise due to the temperature change.

Do you have a ceiling in your house? If you hang the ceiling, there may be a small transmitter installed inside, which is convenient for mobile phones to receive signals, you can find a way to get close to see it yourself, if there is, please ask the property to help you remove.

If you live in a neighborhood, it's rats on the top floor or something, and if you're in the middle, there's a problem with the people living on top.

If you live in a bungalow in your hometown, eighty percent of them are cats or mice.

There are several factors to consider about sound:

1.Sound travels in a straight line. Therefore, a certain amount of blocking can greatly reduce the sound, the higher the place, the less blocking, and of course the more noise sources can be heard.

2.The sound is attenuated, the higher the frequency attenuation, the more powerful the attenuation, for the sound of the normal auditory range, a few levels away, the attenuation is, but it is not as powerful as everyone thinks, otherwise you shout loudly, and the people upstairs will not hear it.

3.Greening can have a certain blocking effect, but it is limited.

As far as personal experience is concerned:

1.Houses on the ground floor are generally noisy, especially old-fashioned neighborhoods. There will be the sound of pedestrians at the window.

2.3-7 floors in the general new community sound is relatively small, 3It will be noisy above the 10th floor, if it is leaning on the elevated or light rail. Floors 10-20 are not suitable.

4.Above the 20th floor due to attenuation, the sound is better.

It depends on the orientation of the house and the surrounding environment. Every house is different. If you are sensitive to sound, you must choose a different time to listen to it when you buy a house.
