The invention relates to an aircraft sound diagnosis method and device. The method comprises: a step (E1a) of measuring acoustic signals (S) by a plurality of microphones (2) mounted at different positions (PS) within the aircraft (AC); a step (E3) of recording the measured acoustic signal (S); a calculation step (E5) of generating a sound plot (CS) on the basis of the measured acoustic signal (S); a step (E6) of comparing the sound plot (CS) and the reference plot (CR); and a step (E7) of transmitting the comparison to the user device (11). The method enables the tracking of abnormal noise or the trend of the abnormal noise level, and helps to determine the background situation thereof.

    本发明涉及飞机声音诊断方法和装置。该方法包括:由安装在飞机(AC)内的不同位置(PS)处的多个麦克风(2)测量声学信号(S)的步骤(E1a);记录测得的声学信号(S)的步骤(E3);基于测得的声学信号(S)生成声音测绘(CS)的计算步骤(E5);比较声音测绘(CS)和参考测绘(CR)的步骤(E6);以及向用户装置(11)传输比较的步骤(E7)。该方法使得能够跟踪异常噪声或异常噪声水平的趋势,并帮助确定其背景情况。
