摘　　要：选取合理的噪声评价指标是机场飞机噪声评估与控制的重要前提。文章分析了部分国家和地区的典型累积事件噪声评价指标,总结了其共性和差异;针对我国计权等效连续感觉噪声级与声环境噪声指标不统一,提出了累积事件噪声新指标;针对现有指标一定程度上湮没夜间噪声事件的影响,新增了夜间噪声评价指标;最后采用广州白云国际机场实际数据开展实例研究,验证改进后评价指标的有效性,研究结果具有一定的现实参考价值。Reasonable selection of noise evaluation index is an important prerequisite for airport noise assessment and control.The typical noise evaluation indexes of some countries and regions were analyzed,and their commonalities and differences were summarized in this paper.To solve the problem that the weighted equivalent continuous perceived noise level in China was in disunity with the acoustic environment noise metric,a new noise metric of cumulative event was proposed.Aiming at the fact that the existing metrics,to a certain degree,neglect the influence of night noise event,a new night assessment metric was put forward.Finally,a case study based on the data of Guangzhou Baiyun International Airport was carried out to verify the effectiveness of the evaluation metrics.It maintains the results are of reference value.
