There s always the sound of picking things up and putting them down at home, is it coming from downs

Now the sound insulation effect of the building is a little unsatisfactory The sound you said may not necessarily come from downstairs Generally, only the noise upstairs will let you hear more clearly Before my family lived on the top floor The noise of the children downstairs can still be heard There is no good way to avoid such a sound After all, there are too many neighbors around.

Some buildings occasionally have strange sounds due to plumbing problems, such as the sound of beads falling to the ground, or other sounds, and possibly the sound of the wind blowing. You can check if it's a human sound, these are quite normal.

It's usually uploaded downstairs, and it's hard for you to hear such a big movement downstairs.

I think in this case, you can install a surveillance camera to see if it's from your home. Now the camera is also very cheap, you can buy one for more than 100 yuan, you can buy one and install it, where you think there is a sound coming out, then you can monitor whether it is your home or not, because from your topic, you don't know whether it is from your home. So install a camera first to see if it's from your family, if not, that's the best, because if it's not from your family, you don't need to worry, as for whether he is downstairs or not, it's none of your business.

Not necessarily, maybe it's a sound from upstairs or outside.

There is always a clang of picking up something and putting it down, either from downstairs or from upstairs.

Most of the voices came from upstairs.

Because the conduction distance is closer upstairs than downstairs.

The sound in the building is transmitted from the walls.

So it could be a neighbor upstairs or left or right.

Because the voices that come out of life are not that loud.

So just look for the neighbors on the left and right.

What a big move from downstairs! Is it from upstairs, maybe from next door, your house is too poor soundproofing, if it is often so, it is too disturbing your life, it is recommended that you look for it and make a hint.

As you said, you often hear this kind of inexplicable sound in buildings, but you can't find that place to hear, sometimes in the dead of night, it also sounds, which is the sound caused by the uneven settlement and deformation of the building.

Follow the sound and take a look!

It may also be from the upstairs next door, sometimes the distance is relatively close, and you can't feel whether it's upstairs or upstairs.

The results are mainly due to the different mediums and paths of sound propagation.

Generally, the sound transmission of solid floor slabs is better than the conduction in the air, and any vibration of the upstairs floor can pass through the floor slab to the wall of your house to receive a relatively large area of sound, and then the distance you hear is relatively direct; The sound downstairs mainly acts on the floor, most of the vibration energy is lost through the wall, and the remaining part is transmitted to your floor through the air.

Yes, that's mechanical waves.

It's fluctuations, and there's a vibration, and the transmission of vibrations causes fluctuations, and high school will learn.

There was a vibrating sound, and I think that in this case, it must be a factor of its own existence, probably due to the transmission of sound vibrations from the upper floor.

When you stick it into the bed, you get a vibrating sound, is it coming from downstairs or upstairs?

It's annoying to fit, it's annoying a lot, a lot of the skin of the People's Liberation Army goes home to fight **.

There is a vibration sound coming close to the bed, which may come from both upstairs and downstairs at this time, and it is difficult to hear at home.

When you get close to the bed, there is a vibrating sound, is it from downstairs or upstairs? You have to see if it's upstairs or downstairs, and if it's upstairs, you can tell him, don't pause.

We all know that sound travels in the form of waves, and generally speaking, the clarity and magnitude of sound are usually determined by the distance between the sound source and the listener, as well as the obstacle in between. The obstacle between the upstairs and downstairs is the same, that is, it is determined by the distance.

Let's go back to your question, analyze it, we first have to look at the position of a large number of sounds in daily life, our noise in life is usually ** in people's mouths and hands, 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 listener, we can calculate, usually the current building floor height is about 3 meters, then the downstairs sound to the upstairs into the distance is the floor height - sound source height + human ear height. 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 significantly greater than the height of the sound source, it is obvious that the distance from the downstairs to the upstairs is smaller than that from the upstairs to the downstairs.

So is it possible to say that it is easier to hear downstairs upstairs?

Actually, what we feel in life is that it's easier to hear upstairs 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.

So it's easier to hear upstairs downstairs.

Theoretically it's the same, but in practice it's better to live upstairs, and the tables and chairs upstairs only touch the floor, and the floor is not very thick and can be heard downstairs.

This one is the same. The sound is diffused outward. It's not like air that goes up. Upstairs and downstairs are the same.

It's the same depending on the thickness of your partitions! Or see if you both can't open the window!

Now the sound insulation of the house is not good, you can install the sound insulation board, KTV is so loud is fine, but the general decoration company will not install, the amount of work is too small. Downstairs should mainly be annoying walking slippers sound, buy a kind of slippers with a cushion under it will be much better, spread a stall in a place that often walks, and your home is not.

Why do you always hear the sound of marbles falling on the ground in the middle of the night? In fact, there is a scientific basis.
