ActiveStandard of aircraft noise for environment around airport
机场周围飞机噪声环境标准
Application Summary AI generated
GB 9660-1988 specifies the allowable noise levels generated by aircraft operations, measured as weighted equivalent continuous perceived noise levels (WECPNL), for areas surrounding airports. It is applied in China to assess and control environmental noise pollution from takeoff, landing, and ground run-up activities, ensuring compliance with residential and sensitive area noise limits. The standard is used by airport authorities, environmental regulators, and urban planners for noise zoning, land-use planning, and monitoring compliance near civil and military airports.
