Abstract: This paper systematically analyzes the basic principle,calculation methods and control standards of the noise metrics of the world’s major countries and regions.A series of experiments were taken on based on the noise monitoring data of a large busy airport.Through the experimental analysis demonstrated the similarities and differences of the airport noise metrics,pointing out that the existing airport noise metrics are not complete and need improvement.

摘要： 分析世界主要国家和地区使用的机场噪声评价量的基本原理、计算方法及控制标准，并基于某大型繁忙机场实际噪声监测数据，通过实验分析论证各机场噪声评价量的共性和差异，指出现有机场噪声评价量的不完备和需改善之处。
