Effects of core position of locally resonant scatterers on low-frequency acoustic absorption in viscoelastic panel

Zhong Jie, Wen Ji-Hong†, Zhao Hong-Gang, Yin Jian-Fei, Yang Hai-Bin

Displacement fields of both the viscoelastic panel and the steel slab corresponding to the absorption peaks of (a) 1650 Hz, (b) 1800 Hz, and (c) 2250 Hz, respectively for core positions 1, 2, and 3.
