Sound-cloaking acoustic metamaterials are on the way

Sound-cloaking acoustic metamaterials are on the way


New materials that have the potential to create acoustically shielded environments may be on the way. In the latest development, researchers have shown how creating materials that have meandering paths for sound waves can result in a negative acoustic index of refraction. More importantly, these materials may actually be manufacturable and work for sound waves in air—the stuff we might consider noise.
