机场周围飞机噪声测量的影响因素分析

简要回顾了机场周围飞机噪声的测量方法、评价指标;针对测量过程中存在的问题,从测量周期、飞行架次分布、机型的代表性、环境背景噪声等几个方面考察了对测量数据的影响,对机场周围飞机噪声测量的影响因素进行了分析;论证了缩短测量周期的可行性,当每天的飞行架次在200架左右时,以3 d取代7 d的做法较为可行;对于飞机噪声测量过程中存在的问题,提出了个人看法和建议。

Analysis of Influential Factors on Measurement of Aircraft Noise Around Airport

This paper briefly reviews the measurement method and evaluation index of aircraft noise around airport; analyzes various Influential factors existing in the measurement process, such as cycle time of measurement, distribution of flights, representation of aircraft type, environmental background noise; demonstrates the feasibility of shortening the measurement cycle time; draws a conclusion tha the practice with 3 days instead of 7 days is more feasible as the daily flights reach about 200 flying sorties; puts forward personal views and suggestions on the problems exiting in measurement process.
