Blackhole Tiles

       Blackhole Tiles offer a unique solution for noise transfer issues in automotive and marine environments. These 4″ x 3″ x 1.5″ water-resistant tiles consist of multiple layers that work together to address this problem. Specifically, they include a 1″ thick acoustic foam layer, a 1/8″ thick 1lb per sq/ft mass loaded vinyl layer, a vibration-isolating closed-cell foam layer, and a high-loss visco-elastic damping layer with a pressure-sensitive adhesive.

       The 1″ thick high-density polyurethane acoustic foam layer absorbs noise to mitigate sound transfer. Meanwhile, the floating mass loaded vinyl layer blocks noise and serves as a wide-band treatment for noise.

       Additionally, the closed-cell foam layer acts as a decoupler for the floating mass loaded vinyl layer to prevent energy transfer from the substrate to the mass loaded vinyl. Finally, the visco-elastic layer offers damping properties to the substrate it is applied to.

       Overall, Blackhole Tiles are a versatile and effective solution that addresses noise transfer issues in vehicles and boats.
