Study on broadband vibration reduction characteristics and optimal design of the acoustic black hole plate with damping oscillators
Abstract The acoustic black hole (ABH) can alter the velocity of bending waves and concentrate vibration energy with the change of thickness. However, the frequency of the ABH is primarily concentrated above the cut-off frequency and the effect on frequencies below the cut-off frequency is negligibl...
