Feng Bo, Director of the Standards Division of the Science and Technology Standards Department of the Ministry of Environmental Protection, said that the release of the new standard has improved the national environmental noise standard system; expanded the scope of application of the standard, and solved the problem of low-frequency noise and lack of noise control requirements outside the city; The standard applies to the object.
According to Feng Bo, the "acoustic environmental quality standard" is applicable to the acoustic environment quality evaluation and management of the five types of acoustic environment functional areas in urban and rural areas. For the areas around the airport that overlap with the five types of functional areas, the clear provisions do not apply to this standard. Implementation of the "Aircraft Noise Environmental Standards around the Airport". However, for ground noise in the area around the airport, the Acoustic Environmental Quality Standards still need to be implemented.
The "Environmental Noise Emission Standard for Industrial Enterprises Boundary" applies to the management of environmental noise emissions from industrial enterprises and fixed equipment boundaries, and also applies to units that emit noise in external environment such as institutions, institutions, and groups. In view of the fact that some of the fixed equipment used in industrial production activities may be independently dispersed, the standard stipulates that the boundaries of various noise-generating fixed equipment are the boundaries of actual land occupation.
The "Social Living Environment Noise Emission Standard" specifies boundary noise emission limits for equipment and facilities that may cause environmental noise pollution in commercial cultural and entertainment venues and commercial business activities. The "Social Living Environment Noise Emission Standard" does not cover all social life noise sources, such as the noise generated by the service facilities of the building, the noise of public places such as streets and squares, and the neighborhood noise such as home decoration.
Zhao Yingmin, director of the Department of Science and Technology Standards of the Ministry of Environmental Protection, said that the revision of the three environmental noise standards fully considered the current changes in noise pollution situation and environmental management needs, fully implemented the concept of people-oriented, building a harmonious society, and improved the coordination of standards. Operability will play an important role in China's economic, social development and environmental protection work.
In the next step, the Ministry of Environmental Protection will revise the longer-aged "Aircraft Noise Environmental Standards around the Airport" and "Building Construction Boundary Noise Limits". For traffic noise, based on the "Boundary Noise Limits and Measurement Methods" standard, the Ministry of Environmental Protection will integrate and formulate environmental noise emission standards for traffic trunk lines, distinguish between new and existing facilities, and propose control requirements.
