Abstract
An acoustic metamaterial layered composite for noise control may include a plurality of micro-perforated plates alternately and periodically arranged with a plurality of absorbent layers and optional air gaps. The plurality of micro-perforated plates may be in a form of a periodically arranged stack and include perforations extending therethrough. Each of the plurality of absorbent layers is formed of a poroelastic material. The metamaterial layered composite noise control device is designed using the metamaterial acoustics transformation approach for optimized noise control.
