本标准描述了噪声测量程序，以表征高噪声环境下的噪声排放 性能（超音速喷射流）军用飞机。具体详细的噪声测量程序 用于描述环境文件（如环境影响文件）的噪声特征 声明和环境评估，以及量化飞机噪音排放。这 本标准描述了常规起飞和起飞的地面助跑和飞越试验的试验程序 着陆、短距离/垂直起飞和着陆操作。信号处理标准也描述了， 数据格式和测量不确定度。

This standard describes noise measurement procedures to characterize the noise emissions from high performance (supersonic jet flow) military aircraft. Specific detailed noise measurement procedures are described for characterizing noise for environmental documents such as environmental impact statements and environmental assessments, and for quantifying aircraft noise emissions. This standard describes test procedures for ground run-up and flyover tests for conventional take-off and landing, short/vertical take-off and landing operations. The standard also describes signal processing, data formatting, and measurement uncertainty.
