In this paper, we deal with vibration damping analysis of acoustic black hole models. We created an acoustic black hole model that has a bidirectional residual plate thickness for the target of study. For comparison, we also made two acoustic black hole models, that has a unidirectional residual plate thickness type and that has no residual plate thickness type. These three models were created by using CAD and FEM. Using these three models, we calculated resonance frequencies and modal loss factors in each mode and compared the vibration damping performance.
