标准范围

1.1本国际标准规定了测量仪器和测试程序的要求以及报告稳定飞行下飞机内部机组人员和乘客位置的声压级条件。声压级可用于确定用于描述声学的各种量。飞机内部的环境。这些程序旨在确保测试结果的一致性，并为确定测量不确定度提供依据。1.2本国际标准提供了完整测量的电声性能规范系统从麦克风到读出设备。测量系统的各种单独部件可以是只要总测量系统符合本国际标准的规范，就可以选择。1.3优选的测量程序包括记录声压信号，随后分析成三分之一倍频程带声压级。可以对三分之一倍频程频带进行直接测量声压级。

1.1 This International Standard specifies requirements for instruments and test procedures for the measurementand reporting of sound pressure levels at crew and passenger locations in the interior of aircraft under steady flightconditions. The sound pressure levels may be used to determine various quantities for describing the acousticalenvironment in the interior of the aircraft. The procedures are intended to ensure uniformity in test results and toprovide the basis for determination of measurement uncertainties.1.2 This International Standard provides electroacoustical performance specifications for a complete measurementsystem from a microphone to the readout device. Various individual components of a measurement system may beselected so long as the total measurement system conforms to the specifications of this International Standard.1.3 The preferred measurement procedure involves the recording of sound pressure signals with subsequentanalysis into one-third-octave band sound pressure levels. Direct measurements may be made of one-third-octavebandsound pressure levels.
