摘　　要：为明确机场噪声烦恼度的影响因素,并以此来分析哪个是更适合我国国情的机场噪声评价指标。本文根据国内某机场周边点位的噪声监测数据和主观烦恼度调查,对影响公众烦恼度的原因因素进行排序,使用Friedman检验分析各因素对烦恼度的影响权重,在此基础上进一步讨论我国新旧噪声评价指标与公众烦恼度阈值之间的关系。结果表明:飞机噪声发生时间段是决定公众烦恼度的最主要因素,公众所处的区域类型是次要因素,飞机噪声大小对居民烦恼度的影响最小;同时确定了我国新旧噪声评价指标的公众烦恼度阈值,进一步证明了L dn比L WECPN更直观地表现出区域声环境和飞机噪声之间的关系,能更好地和声环境质量标准进行衔接。To clarify the influencing factors of airport noise annoyance and use them to analyze which is a more suitable airport noise evaluation index for our national conditions.In this paper,based on noise monitoring data and subjective annoyance survey of the points around an airport in China,the causal factors influencing public annoyance are ranked,and the influence weight of each factor on annoyance is analyzed using Friedman test,based on which the relationship between old and new noise evaluation indexes and public annoyance thresholds in China is further discussed.Results:the time period when aircraft noise occurs is the most important factor in determining the public annoyance,the type of area where the public is located is a secondary factor,and the level of aircraft noise has the least influence on the annoyance of residents;meanwhile,the public annoyance thresholds of China s old and new noise evaluation indexes are determined,which further proves that L dn can show the relationship between regional sound environment and aircraft noise more intuitively than L WECPN,and can better connect with sound environment quality standards.
