  • Viscoelastic phononic crystal
    Patent number: 9324312
    Abstract: A sound barrier and method of sound insulation are disclosed. In one aspect of the disclosure, a sound barrier comprises a first, solid medium, such as a viscoelastic solid and a second medium, such as air. At least one of the two media forms a periodic array disposed in the other medium. The solid medium has a speed of propagation of longitudinal sound wave and a speed of propagation of transverse sound wave, the speed of propagation of longitudinal sound wave being at least about 30 times the speed of propagation of transverse sound wave.
    Type: Grant

  • Solid-state acoustic metamaterial and method of using same to focus sound
    Patent number: 8596410
    Abstract: A phonemic crystal is made of a first solid medium having a first density and a substantially periodic array of structures disposed in the first medium, the structures being made of a second solid medium having a second density different from the first density. The first medium has a speed of propagation of longitudinal sound waves and a speed of propagation of transverse sound waves, the speed of propagation of longitudinal sound waves being approximately that of a fluid, and the speed of the propagation of transverse sound waves being smaller than the speed of propagation of longitudinal sound waves.
