  1. What city are we talking about? I suspect that the reasons vary greatly depending on the region. Because in Perm, for example, this is due to a local decision of the local administration. After the crisis of ' 98, the question of an acute shortage of jobs arose, each region solved it in its own way, and in Perm, to increase jobs, a special administrative unit “manager for rolling balls in apartment buildings” was introduced (clay ones – with < 20 years of work experience, iron ones > 20 years). Since these people were constantly asked about the purpose and meaning of their work, and they could not answer anything, they gradually learned to perform their duties without being noticed by the inhabitants of the house. They get somewhere in the order of nine thousand (with clay) and eleven thousand (with iron), that is, they fit into the subsistence minimum.

  2. Gentlemen, everything is much simpler. These are not metal or clay balls, but empty glass bottles that once contained alcohol, and they roll around the apartment from above by a simple Providence that often visits people like me.

    Your neighbor from above.

  3. I know this sound well! In the panel house where we lived, the neighbors from above constantly ” dropped glass balls on the floor.” The “balls” rolled out with a characteristic sound and we, the children, really wanted to understand: why do they have so many of these balls and why do they constantly drop them? And when we asked our parents these questions, dad and mom (natural scientists, not techies and not humanities) laughed and said that the neighbors ' refrigerator is close to the wall. Therefore, when it is periodically turned off, it makes contact with nearby surfaces and gives this characteristic sound. But I still don't believe it and just see blue and green glass balls spilling out of the bag onto the floor and rolling around the apartment. For those who are young, I will add: to have a glass ball is the blue dream of any Soviet child. And to have a whole bag with such balls is a luxury that you can not even imagine! 🙂

  4. The rolling ball phenomenon. It is usually found in panel houses, less often in brick ones, and has nothing to do with something otherworldly.

    This effect is especially noticeable in homes made of reinforced concrete slabs, as well as other materials that have air voids. During the day, when the ambient temperature is higher, the structure heats up. During the evening and night hours, when the temperature drops, the materials give off heat, and the voids create a sound effect that resembles the sound of a rolling ball. This explains the fact that these sounds are usually heard at night.

  5. Sometimes my neighbors come to me with such complaints, and quite justified, I play petanque and I have a dozen steel balls on the floor, which are touched by livestock and they roll with a characteristic sound. The same applies to dumbbells on the floor.

  6. Diuzia, it's much easier than you might think: the sound of balloons rolling is caused by the heavy doors of your neighbors ' closet from above. The door with the help of special rollers rides along the guides, which are bolted directly to the floor. The door is heavy, usually mirrored, so you can hear the dull sound of its movement, so similar to the rolling of large balls on the floor. And this can happen, as you know, at any time of the day or night, when your neighbor needs something in the closet again. Good night.

  7. I can offer an addition to the answer above. Where I live, the metro has been under construction for several years. Explosives are used to build tunnels, but I do not know exactly how deep they blow up. The fact that an explosion is about to happen, I know by the sound of a siren, because the construction site is a couple of hundred meters away. If the explosion is not far away, it sounds as if the neighbor from above dropped a bag of heavy lead balls on the floor. I used to live further away from the metro construction site, and there the sounds were like someone moving furniture, and they always coincided with the time when the blasting works were being carried out.

    Perhaps the sounds described in this question are somehow related to the vibration transmitted to the ceilings from any construction work (from my experience, I can say that it is felt at a distance of about a kilometer).

  8. All the answers from the category “these are hallucinations”, as well as options with cabinets and furniture and the subway and elevators and temperatures and shrinkage and bottles and so on can only be offered by people who have never heard this sound.

    First the ball falls (!), it is quite heavy, then it jumps again or twice with fading intensity, and then it rolls and disappears.

    It doesn't crash into a wall, it doesn't change speed, the sound is always the same along the length, no one has ever interrupted the sound of the ball after the first impact on the floor(respectively, I have a ceiling where the sound comes from), no one has changed its trajectory(assuming that this is a real ball and a cat), the sound Then a break is required, sometimes this break can last several hours, sometimes months. The sound occurs at any time, both day and night, morning and evening, completely independent of the time of year and the temperature outside the window, from the wind and rain. At the same time, this sound is heard by everyone in the room, it occurs in any room in any place and direction.

    Just drops and rolls the ball.

  9. Oliver Sacks in Hallucinations describes examples of hallucinations similar to this one. The general message of the author is that such milky hallucinations are a fairly common phenomenon, and can occur in quite healthy people. In addition to rolling balls, there are also footsteps, the sound of phone rings and even the voices of friends. And all this is just a side effect of some brain function. Something like that. Of course, the steps can also be real, if, for example, relatives with children and animals came to the neighbors from above 😉

  10. Comrades, the fact is that this is the tricks of a reptilian domovenka. Reptilian brownies have independently managed the process of building buildings on the territory of Russia since the beginning of the XVII century. Let me remind you that the beginning of the XVII century was marked by the Time of Troubles, when Polish interventionists tried to seize power in our state. It was then that the reptilian brownies came to us together with the Polish interventionists and are still trying to destroy the Russian people by rolling balloons on the top floor.

  11. I had a case here recently!

    We are sitting at home with a young man, going to sleep, and then we hear the balloons, and so loudly and clearly. Well, as you began to argue, they say why and why. And the sound doesn't stop.

    And then, about 20 minutes later, a balloon rolls out from under our bed, crosses a third of the room, and rolls back up. Then it rolls out again! It turned out that our cat is hanging out under the bed, playing football, and the floor in our room is very crooked – so the ball always rolls back to him 🙂 That's how cat fun made us break our heads

  12. Since Russian science has not solved this issue, I turned on the physicist and it seems that I have solved the riddle of the century. The answer lay on the surface. attention

    These are coins that fall to the floor and come to a stable equilibrium position for a while(tested empirically). There are two types of sound

    1. Crumbling Beads
    2. Rolling glass ball.
      �Therefore, the sound that you will hear depends on the material security of the neighbors. The loudness of this sound is due to the resonance of the armature, because in fact mechanical, not sound vibrations, are transmitted to it.

    The appearance of sound only in panel houses is explained by the fact that the plates have very high sound transmission due to the presence of reinforcement.

    The failure of the theory of temperature deformation of plates proves the audibility exclusively from the ceiling, and not from the floor and walls.

    P.S. There are no refutations of the theory of “neighbors who like to roll balls” yet(

  13. Surely many people have heard strange sounds from above, as if someone is rolling balls on the floor. So, the myth is destroyed! These are not balloons at all, but just people who move away from the table on a wheelchair. Exactly. If they do not have a carpet in their room, the sound will be heard by the neighbors.�

    Try it yourself, and everything will fall into place 🙂

  14. My family and I have also been asking ourselves this question for six months. Then it dawned on my father that it was the neighbors upstairs vacuuming, but it felt like something was being rolled on top. A bowling ball, for example.

  15. And in a private house, if someone ran loudly on the ceiling, is it a brownie? Or a cat (even though it's not there)? I live in a private house and sometimes notice this.

  16. I work as a mechanic in a bowling club, the track mechanisms are old, there is a lot of work, so I often have to take the work of debugging the mechanism at home and work at night. Please tell the owner of the club to buy a new oboroduvanie!

  17. I periodically, every night, lay out the sofa. I'm pretty sure the downstairs neighbor is also guessing …

    I also sometimes lean back in my chair and laugh out loud. at this point, the chair also rolls on the floor

  18. I heard that for money you can disable this bug or replace it with more pleasant sounds, for example, the noise of a drill, sounds of sex, surf, seagulls, shawarma beer pies….. oh that's me.

  19. This phenomenon can be observed in panel houses, mainly in new ones. We are talking about the temperature stress in the reinforcement of reinforced concrete structures, in particular, floors. The bottom line is this: during the day, building structures heat up and deform due to thermal expansion. In the reinforcement frame of the plates, stresses occur (roughly speaking, the reinforcement rods bend or contract quite a bit). There is nothing terrible in this for the strength of the building, moreover, these deformations are provided for by the project. At night, the temperature of the outside air, and, consequently, of concrete structures, falls, and at a certain moment the reinforcement relaxes (the very “ball drop”), followed by an oscillatory return of the reinforcement to its original position (and the “ball rolls”). Sound propagation is helped, firstly, by the material of the structures itself (reinforced concrete conducts sound very well, any resident of a panel house will confirm this to you), and secondly, by the abundance of voids both in the slabs and in the building itself, which generates acoustic resonance.

  20. This is just furniture on wheels, in particular – chairs with plastic wheels. Hydraulics soften the weight of a person and therefore the sound from a rolling wheel seems more voluminous and soft

  21. I think the most plausible version is the vibration propagation from the elevator.

    I have never seen anything like this in buildings without elevators, for example, in the three-story blocky private house in which I live, and in the four-story monolithic country house in which I live in the summer, in the five-story apartment building where I come to visit my sister, and in the five-story Stalinka, where I live during business trips.

    But when I visit houses with elevators, I often see this.

    I can also assume that this effect is observed only in panel houses.

  22. The phenomenon of balloons rolling over the ceiling is one of the main mysteries of our time. Unfortunately, Russian science is in a state of chronic underfunding, and in the West this phenomenon is not very well known, so local scientists spend money on all sorts of rubbish, like catching the Higgs boson, but real science is worth it. I hope that sooner or later Rusnano will allocate sufficient funds for the construction of the Bolshaya Andronnaya Khrushchevka in order to finally solve this painful issue for entire generations of Russian citizens.

    I have read many discussions of this phenomenon, for example livejournal.com or ixbt.com , but there is no reliable solution in them. The most plausible version seems to me about the relaxation of stresses in reinforced concrete floors, associated either with the daily temperature cycle, or with the subsidence of the building, or with the shrinkage of the floors themselves. In any case, these are not neighbors – they were reliably checked many times. And, most likely, not balloons.
