Determining the "loudest recorded sound" depends on how you define sound and on which measurements you choose to include.

Scientists at the University of Glasgow have confirmed a half-century-old theory that claimed a super-advanced alien civilization could use a black hole as an energy source. By using sound waves, the ...

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...

Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A 'hot' trail to explain this effect leads to a region of the solar ...

Mechanical engineers have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as 'acoustic tweezers, ...
