本文以同一作者的早期工作为基础，利用多个麦克风元件的自谱密度和互谱密度推导频域中时间平均声能量密度的表达式。推导了最常见的三维几何排列的表达式。还提供了与两个通道频谱分析仪一起使用的简化表达式。
This paper builds on earlier work by the same authors to derive expressions for the time-averaged acoustic energy density in the frequency domain using the auto- and cross-spectral densities of multiple microphone elements. Expressions for the most common three-dimensional geometric arrangements are derived. Simplified expressions for use with two channel spectrum analysers are also presented.
