◉ Introduction to Noise in Construction Site
Building construction refers to the production activities in the implementation stage of project construction, and is the construction process of various types of buildings, including earthwork construction, foundation engineering construction, main structure construction, roofing engineering construction, and decoration engineering construction (residential buildings that have been completed and delivered Except for decoration activities), etc.
The boundary of the construction site is approved by the relevant competent authority or the boundary of the construction site actually used in the construction process.
Construction site boundary noise refers to the environmental noise generated by the construction site during urban construction, and its noise limit mainly refers to the limit at the boundary line of the construction site corresponding to the sensitive area. Noise limits for several construction phases.
◉ Test Items
Construction noise includes daytime noise and nighttime noise. "Daytime" refers to the period between 6:00 and 22:00; "night" refers to the period between 22:00 and 6:00 the next day.
If the people's government at or above the county level has other regulations on the division of daytime and nighttime for the needs of environmental noise pollution prevention and control (such as taking into account the time difference, differences in work and rest habits, etc.), such regulations shall be followed.

Environmental Noise Emission Limits at the Boundary of Construction Sites
|
Day Time（6:00-22:00） |
Night Time（22:00-6:00） |
|
70dB |
55dB |
|
Note: During the construction process, the ambient noise at the site boundary shall not exceed this standard • The maximum noise level at night shall not exceed the limit by more than 15dB(A). • When the noise-sensitive building is close to the field boundary, and the outdoor environment does not meet the measurement conditions, it can be measured indoors in the noise-sensitive building, and the corresponding limit in the table shall be reduced by 10dB(A) as the evaluation basis. *Noise-sensitive buildings refer to buildings that need to be kept quiet, such as hospitals, schools, institutions, scientific research units, and residences. |
