基于统计最优的近场声全息理论与仿真实验

摘要

Based on the SOPNAH technology research ,a Tikhonov regularization method is proposed ,and the optimal regularization parameter λis selected .Simulation results show the combination of Tikhonov regularization method and SOPNAH can accurately locate the noise source and achieve sound field reconstruction ,has higher reconstruction accuracy than the traditional method .%对统计最优平面近场声全息（SOPNAH）技术进行研究，提出了一种吉洪诺夫（Tikhonov）正则化方法并选择最优正则化参数λ。通过仿真实验验证了结合吉洪诺夫正则化方法的SOPNAH能够对噪声源进行准确定位及实现声场重建，并且重建的精度比传统的方法更高。
