1. IntroductionNear−field Acoustic Holography (NAH) technology [1] has been widely used for source identification and visualization of spatial sound fields. NAH technology has multiple solving methods [2,3,4], among which the Equivalent Source Method (ESM) [5] is widely used and researched in the NAH field due to its simple model, adaptability to any shaped sound source, and high reconstruction accuracy and computational efficiency.
