Humans interact with sound in many ways, and our ability to control sound—including generating it, steering it, and absorbing it—is essential in many applications. Conventional, off-the-shelf materials offer rather limited ways to do this. Steven A. Cummer (Professor, Electrical and Computer Engineering Department, Duke University) will talk on the science and application of acoustic metamaterials, or artificial materials for sound, which enable us to create engineered structures to manipulate and control sound waves in ways that are not possible with ordinary materials. This includes creating acoustic holograms that can project a sound field with an almost arbitrary physical shape, and designing acoustic cloaking materials that can make an object effectively invisible to sound.
