摘要
本文提出在多振源工况下用相干功率谱辨识噪声源方法;对被识别出的声源进行自谱和倒功率谱分折。
Recommendations are made that a noise source in ulti-vibration source circumstances be identified by coherent spectrum and analyzed by power spectrum and reverse power spectrum, so that the part of equipment in a particular factory which is responsible for the noise can be pinpointed and hence specific couatermeasures taken
