<P>PROBLEM TO BE SOLVED: To provide a method which automatically measures noise and effectively eliminates covering sound, in the analysis of aircraft noise data. <P>SOLUTION: In the method of analyzing and processing aircraft noise data: noise data obtained by an optional measuring station on an optional day are sorted, in the descending order of noise level waveforms, and displayed on a display device starting from the largest noise level waveform, and/or they are reproduced by an acoustic reproducing device; and only the noise level waveforms not less than a numerical value obtained by multiplying a noise evaluation value, such as WECPNL value, LAeq value or the like by a prescribed certain contribution ratio, are observed visually by the operator; and noises other than aircraft noises are determined and eliminated therefrom. <P>COPYRIGHT: (C)2009,JPO&INPIT |
