A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on ...

Sound wave techniques are experimental and analytical methods that generate, manipulate, and detect acoustic waves to probe, image, or modify materials and systems. In research, they encompass ...

Researchers designed a novel heat pump that uses sound waves to move thermal energy, producing additional heat. The team from China produced an unprecedented amount of heat with their system, and ...
