声学.机场附近飞机噪声的无人监测

[中文适用范围]： 本国际标准规定了：a) 机场周围永久安装的声音监测系统典型应用；b) 仪器性能规格及其无人值守安装和运行的要求，以确定选定位置的飞机声音的连续监测声压级；c) 监测机场飞机运行声音的要求；d) 描述飞机运行声音所需确定量的要求；e) 报告数据的要求和报告发布频率；f) 根据 ISO/IEC 指南 98-3 确定报告数据扩展不确定度的程序。本国际标准不提供：确认或验证预测声轮廓的方法；确定、验证或确认飞机噪声认证数据的方法；描述飞机在地面时（包括地面移动和使用辅助动力装置）产生的声音的方法，但起飞滑跑开始后在跑道上和降落触地后离开跑道前的情况除外。 [外文原描述]： ISO 20906:2009 specifies: a) the typical application for a permanently installed sound-monitoring system around an airport; b) performance specifications for instruments, and requirements for their unattended installation and operation, so as to determine continuously monitored sound pressure levels of aircraft sound at selected locations; c) requirements for monitoring the sound of aircraft operations from an airport; d) requirements for the quantities to be determined to describe the sound of aircraft operations; e) requirements for data to be reported and frequency of publication of reports; f) a procedure for determining the expanded uncertainty of the reported data in accordance with ISO/IEC Guide 98-3 . ISO 20906:2009 does not provide: 1) a method for confirming or validating predicted sound contours; 2) a method for determining, validating or confirming aircraft noise certification data; 3) a method for describing the sound generated by aircraft while on the ground (including ground movements and the use of auxiliary power units), except while on the runway after start of roll for departures and between touchdown and leaving the runway for arrivals.
