TL;DR: In this article, a frequency domain convolution blind source separation multi-band and multi-centroid clustering sorting method is proposed, where the whole frequency band is uniformly divided into a plurality of sub bands, and overlapping frequency bands are arranged between the sub bands.

TL;DR: In this paper, a case equipment surface acoustic field reconstruction method based on statistical optimal near field acoustic holography is proposed, where a measuring surface conformal with the case structure equipment is used to acquire holographic acoustic pressure, and the surface acoustic fields of the case structural equipment is calculated through the linear superposition of the complex acoustic pressure on the holographic surface of the spatial domain by using a statistical optimal column surface near field acyclic theory algorithm.
