Underwater noise radiated (URN) from ships represents a growing
concern for the international community. The Acoustic Black Hole
(ABH) combined with viscoelastic materials (VEMs), is a promising
new solution for mitigating URN. In this paper, we present the
characterization of an acoustic black hole for marine applications. The
proposed procedure combines a method for the evaluation of VEM
properties of high-damping materials and the analysis of the parameters
that control the ABH performance. The results show the effectiveness of
the ABH in mitigating low-frequency (50 – 200 Hz) ship’s radiated
noise.
