In each situation we should act differently. For example, your neighbours are quite normal people who had not made a noise, and now they have some kind of celebration, a protracted late? To make trouble, to put forward a claim hardly. It is better to do the following: go to the neighbors, congratulate them on a triumph and politely ask them to turn down the music volume. With a probability of 99% you and willing to go forward, and even apologize for the inconvenience. It so happens that the people, excited joyful meeting and consumed the alcohol, just do not hit upon such a simple thing.

If night noise is repeated with unfortunate regularity, and to neighbors does not "get it" - write a complaint to the local police. He is obliged to respond. Unfortunately, our law is too loyal to the violators of peace and quiet, so at first the neighbors will be given a warning, then the case may go to penalty. Alas, its size hardly scare off ill-mannered people (particularly if they lead asocial way of life), but it's better than nothing.

Filed a lawsuit in court demanding compensation of moral damage. Get ready in advance to the fact that it is a difficult matter that requires time and nerves. Because under the law the burden of proof lies on you to ensure, for example, testimony. As witnesses there may be other neighbors also suffering from night noise. There have been cases in judicial practice where the lovers of loud music is not only pay very substantial fines, and carried a much more serious punishment. For example, in one Chinese city residents, driven "to distraction" restless neighbour DJ, who has been involved with the music at full volume, achieved his eviction. Harsh but fair lesson.
