Abstract

Phononic crystals embedded with acoustic black hole (ABH) structure have excellent performance absorbing structural waves in elastic bodies. However, it is not easy to be applied in practice because of the narrow sound absorption band. In this paper, we propose a new type of phononic crystal that embeds the acoustic black hole structure and destructive interference structure. The simulated and measured elastic wave transmission indicate that the vibration in the structure is reduced by 40 dB in the broad range of 100–50,000 Hz, which may provide a new path for wide-frequency vibration isolation and noise control.
