| 摘 要： | 通过驾驶舱话音记录器(CVR)录制了某飞机5种典型事件信息,如飞机飞行时左发动机故障、飞机起落架动作等,然后对录制的CVR信息进行滤波、A/D转换,利用Goldwave音频特效处理软件和窗口傅里叶变换(WFT)进行处理和分析.分析结果和理论计算值吻合,这为分析简单CVR声信息提供了一种有效方法. |

| Abstract: | Five typical flight information are recorded by cockpit voice recorder(CVR),such as left engine failure and landing gear actuation;then analyses are carried out through filtering,A/D transform,Goldwave audio soft and windowed Fourier transform(WFT).The analysis result is identical with the theory calculation value.A practicable analysis method for simple CVR's sound information is put forward. |
| Keywords: | windowed Fourier transform(WFT) cockpit voice recorder(CVR) airplane sound information analysis |
