| 摘 要： | 针对国产电机听觉上感到噪声偏高的问题 ,选择某型号电机进行了噪声测试 ,采用对数自功率谱、倒频谱和小波分析等方法进行了分析 ,找出了人的听阈不悦的几个高谱峰位置。通过与理论计算结果进行对比分析 ,进一步找出了产生该频阈谱峰的几个原因 ,提出了避免产生该频阈谱峰的改进措施

Diagnosis of Hearing-Disamenity Noise from Electromotor |
| |
| Abstract: | Aiming at solving the problem of hearing-disame nity high frequency noise made by Chinese electromotor, We choose a certain type of electromotor for testing. The noise signal is analyzed by logarithm self-po wer spectrum, converse spectrum and wavelet. Several high spectral peaks that ma ke peoples' hearing disamenity are found. By comparison with theoretic calculati on and further analysis, the cause of producing these spectral peaks is located. The improvement measure for avoiding producing these spectral peaks is put forw ard at the end of the paper. |
