| 摘 要： | 文章先分析谱相关和人耳听觉的某些相似特性,如两者都不管信号的初相位,即使相位相差90°的正弦和余弦信号,只要频率相同人耳听到的是同样的声音,而谱相关系数也接近于1。然后,利用谱相关系数模拟人耳听觉的某些特性,提出一个机器故障诊断设备的框架。

| Abstract: | Similarities between spectral correlation and the sense of hearing are analyzed in this paper. For example, they are both irrespective of the signal's initial phase. Whether the signal is sine or cosine, it sounds identical as long as the frequencies are the same, and the spectral correlation is approximately unit. Based upon this phenomenon, a framework of apparatus for imitating the hearing sense used in troubleshooting machine faults is proposed. |
