What should I do if my neighbors are noisy upstairs?

You can write a note and stick it in front of the neighbor's house, telling him that it has interfered with your life, or directly negotiate with the neighbor who has disturbed the people.

Noise generally refers to noise. The standard usage of noise is noise. From the physiological point of view, any sound that interferes with people's rest, study and work and the sound that people want to hear, that is, unnecessary sound, are collectively called noise. When noise has a bad influence on people and the surrounding environment, noise pollution is formed.
