摘要
An acoustic noise attenuator is disclosed comprising a movable body, an electrical energy storage element and an electrical energy dissipater. The movable body is configured to oscillate when a mechanical disturbance caused by a sound wave, such as acoustic noise, is incident thereon. The oscillation of the movable body induces an alternating electrical energy in the energy storage element. The electrical energy dissipater dissipates the induced electrical energy in the form of heat. An acoustic noise attenuator assembly and a metamaterial structure comprising such acoustic noise attenuators are also disclosed.
