Abstract
Provided is an acoustic article and related methods of manufacture and use. The acoustic article includes a continuous layer having a first elastic stiffness, and a plurality of distributed masses disposed on a major surface of the continuous layer having a second elastic stiffness. The second elastic stiffness can be less than the first elastic stiffness to provide an acoustic metamaterial displaying an anti-resonance peak at a frequency below 800 Hz. The acoustic article can be made using efficient and scalable processes for manufacturing low frequency acoustic barrier materials.
