- The proposed passive destructive interference model allows the development of acoustic metamaterials demonstrating a new way to control and manipulate sound that is unachievable through conventional materials. The proposed model can be used for passive noise cancellation where the sound insulation goes beyond the mass-density law; an aspect that is considered the future wave manipulation. The model offers the potential to solve the current limitations associated with bulk materials in sound absorption, insulation, cloaking, and imaging. The proposed model was exploited by Liu et al. [1] who developed a phononic crystal for controlling shear wave.
