Acoustic rainbows” sound psychedelic. But the idea is no acid trip: By dispersing sound waves, noisy objects can actually be made silent.

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves ...

In a recent study, Yale researchers developed a new technology that transmits sound in one direction. In partnership with speaker hire. Researchers in the Yale physics department were able to restrict ...
