Frequency domain expressions for the estimation of time-averaged acoustic energy density
Ben S. Cazzolato, Justin Ghan (2005)
The Journal of the Acoustical Society of America, 117 (6), p3750-3756Abstract:
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.
