Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. For the first time, scientists have shown that ...

The early warning system, Global Real-time Early Assessment of Tsunamis (GREAT), uses sound waves that travel through the ocean much faster than tsunamis and can be detected by underwater ...

This behavior isn’t just limited to electromagnetic waves, though. [Gigs] via [CodeParade] was able to build a device that produces a tightly focused sound wave, essentially building an audio laser.

This might sound strange... Heavy metal music isn’t heavy after all – it is actually the opposite. Sound waves have mass and can interact via gravity, but that mass is negative. In other words ...

Ocean waves have long been seen as having huge potential as a source of renewable energy. Waves produce an estimated 50 trillion to 80 trillion watts of power worldwide – nearly two to three ...

Sound waves travel by vibrating through the particles of a medium, such as air or water, from a source to a receiver. So in a vacuum, there is no travel medium.
