the night measurement of the first-class living area is more than 51 decibels, and the night measurement of the second-class living area is more than 65 decibels. As long as it exceeds 22: 11 pm or until 6: 11 am the next day, it is a nuisance and belongs to noise pollution. If there are behaviors within these categories in your place, it is a nuisance. According to national regulations, in residential areas, the allowable outdoor noise level is 51 decibels during the day and 41 decibels at night.

legal basis: article 31 of the law of the people's Republic of China on the prevention and control of environmental noise pollution prohibits the construction of buildings that produce environmental noise pollution at night in areas where noise-sensitive buildings are concentrated in urban areas, except for emergency repairs, emergency rescue operations and continuous operations due to production process requirements or special needs. If continuous operation is necessary due to special needs, there must be a certificate from the people's government at or above the county level or its relevant competent department. The night operation specified in the preceding paragraph must be announced to nearby residents.
