Method 1, legal.
You should know that any noise from neighboring apartments is permissible from 7 am to 23 pm, at other times all tenants of apartment buildings are required to observe silence.
But there are also days off, and on weekdays it's difficult to radiate understanding if the neighbor's puncher works every day for a month. It is clear that all this is terribly hampering, especially those who work at home or are sitting with a small child.
You have the right to apply to the district militiaman with a request to influence the neighbors. If they are conscious people, they will take the words of the policeman and, possibly, reduce the sound of the TV or music center, try not to beat the dishes or drill the walls without breaks for lunch. In the event that your neighbors are "on your mind", you will have to act more strictly.
To start, call the SES and find out the permissible noise level in the living quarters of your city or district. If you are sure that it is significantly exceeded, ask to measure the noise level and draw up an act. With this act, you have the right to go to court and file a lawsuit against troubled tenants. On a large moral compensation should not be counted, but quieter, maybe, will.
If your neighbors smoke at night, feel free to call the police on 02. Your call must react, sometimes such departure does not end with a reprimand or a fine - depending on the situation.
If apart from you there are tenants who are also worried about the noise from the neighboring apartment, get their support - collective signatures and efforts are often more effective.
If there is a chairman in your house, any other responsible person, it makes sense to apply to him. It is unlikely that he will be able to influence the tenants, but to control them is perfectly capable, and in case of violation you will have another witness.
It is important to remain calm, getting involved in such a large-scale war. Do not write anonymous offensive or threatening notes, do not insult your neighbors. If you are not sure that you will be able to communicate in a civilized way or you doubt that your neighbors can adequately react to claims, reduce communication to a minimum in the presence of government officials.
Method 2, peaceful.
No matter how incredible this may sound, many neighbors manage to negotiate peacefully.
First, think about what exactly does not suit you, and what would you like to say to your neighbors. Do not go to understand the fuse, usually this leads to a quarrel, and not to solving the problem. If you have a really good reason to voice your claims, you have every right to do so. But think, do not carp at you? It's one thing to fight and loud music at night, another thing is too loud, as you think, talking on the phone.
Approach your neighbors when everything is quiet. Friendlyly explain that you do not like, for what reason and what way out of the situation you see. For example, if the neighbors started repairing, and you have a small child who goes to bed early, explain it. If you yourself are inclined to prevent other residents from sleeping, think about how your reproaches from the outside will look like.
Modern houses do not have good sound insulation, so it is often not clear from which side the noise comes from. Make sure that you are calling the right door when you are coming to an agreement.
Be ready to make concessions. Even if you consider yourself to be exemplary neighbors, do not be surprised if it turns out that you sometimes inconvenience someone. Therefore, agree to mutual concessions.
Do not threaten or insult your neighbors. This can push them to even more noisy behavior and the conflict will enter a new stage of the Cold War.
In the event that your attempts to make contact and inform the neighbors about the essence of the problem, did not have success, do not aggravate the situation, but contact the district militiaman. It is important not to bring the matter to mutual insults and the more so fights, then neighbors will have an occasion to file a complaint against you.
Of course, war with neighbors does not always end in your favor. There are people who do not respond to requests, do not happen to the district police, openly go to conflicts, even regularly pay fines, but continue to make noise. In these cases, you need to try as sound as possible to soundproof the ceilings and walls, do not give up and continue to fight. In an extreme situation, many people decide to move, but this does not give any guarantee that you will not be in a similar situation again. Try all ways to pacify your neighbors, one of them will surely work. Only do not descend to small dirty tricks and revenge, it can end badly and lead to unexpected consequences for which you will be responsible. And are you ready to meet furious neighbors on the threshold of your apartment every time you open the door?
If, however, you are in the role of abusers, apologize to your neighbors, eliminate the cause of the inconvenience and try not to repeat the mistake. In the event that you are undertaking noisy fun or repairs, it makes sense to ask the neighbors about patience for a certain time and apologize in an amicable way.
I'm glad that there are really difficult situations when there is no way out of the situation, there are far fewer of those who can change something.
