Despite the emergence of acoustic metamaterials with superior sound absorption and
transmission loss, their adoption for building sound insulation has been limited. Sound …

Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Acoustic metamaterials (AMs), which are materials composed of subwavelength periodic
artificial structures with specific designs, have drawn significant research attention. This is …

Acoustic metamaterials can manipulate and control sound waves in ways that are not
