The underwater anechoic coating with local resonant units is an effective method to achieve low-frequency sound absorption. However, the structure obtained in this way is not satisfactory in the sound absorption effect of mid-high frequency bands. Ca

Although the conventional locally resonant acoustic metamaterials (LRAMs) have shown better sound absorption performance in the low frequency band, the effective frequency range of the sound absorption performance is quite narrow relatively. To overc

Simultaneous perturbation stochastic approximation (SPSA) algorithm, an algorithm without secondary path modeling, has been applied to active noise control by some researchers. Some extended versions of this algorithm have been also developed to impr
