On December 24,2021, the 32nd Session of the Standing Committee of the 13th National People?s Congress voted to adopt the Law of the People?s Republic of China on the Prevention and Control of Noise Pollution, which shall come into force on June 5,2022, and the Law on the Prevention and Control of Environmental Noise Pollution shall be repealed at the same time.

Article 41 of the Noise Pollution Law of the People?s Republic of China on the People?s Prevention and Control of Noise Pollution stipulates: " Except for industrial noise, building noise and traffic noise, the noise caused to the living environment of surrounding residents refers to the noise caused by human activities."Therefore, any sound, as long as it is artificial, will affect the life around it, and can be regarded as the noise of human life.

Therefore, the scope of social life noise is especially wide, such as commercial activities, cultural and recreational activities, the noise generated by the use of fixed devices in sports, the noise generated by crowd activities (for example, the sound of the vegetable market, the noise during meals) and so on. To judge whether a sound is noise, we should not simply use physical indicators such as loudness and audio. For example, songs in square dance sound like music during movement, but during work, study and rest, it is noise.
