Abstract To address the challenge of controlling low-frequency vibration noise, a coupling phononic crystal model embedded with acoustic black hole (ABH) structures has been designed. By comprehensively studying complex dispersion curves, modes, and transmission loss, we numerically demonstrate that this structure exhibits good sound insulation performance in range 64.3 Hz∼665.4 Hz, bandgap coverage reaches 92.7%, while effective achieves 89.6% within frequency 1000 Hz. The torsional scatterer component is more conducive to lowering first starting frequency, larger torsion angle further contributes reduction. However, cutoff predominantly caused by oscillating along z-direction ABH structure. Evanescent waves exist all studied bands exhibiting strong correlation curve loss. intensity evanescent wave depends on activated state structures, lower imaginary part corresponding passband yields energy loss wave. Damping materials benefit waves. Parameters dependence truncation thickness, length bending uniform are analyzed, which expected provide theoretical design guidance for control attenuation noise.
