What is the legal definition of construction noise?

The definition of environmental noise pollution includes two basic elements. First, it must exceed the national environmental noise emission standards. If it does not exceed this standard, it does not constitute "environmental noise pollution", and even if citizens are infringed by this environmental noise, it is not guaranteed by this law; It does not belong to "environmental noise pollution" if it interferes with the normal life, work and study of others and exceeds the national environmental noise emission standard, but it does not affect the normal life, work and study of others. This standard is applicable to areas with residential, cultural and educational institutions as the mainstay. Rural living environment can refer to the implementation of such standards: 55 decibels during the day and 45 decibels at night. Using instruments to measure in residents' homes: more than 55 decibels during the day and more than 45 decibels at night are disturbing the people. The competent unit for measuring noise pollution is the local environmental protection bureau. There is noise pollution, please report it to the local environmental protection bureau.
