Sound is not just something we hear—it’s vibration, and vibration interacts directly with the human body at a cellular level.

Remington Bixby Hotchkis thinks fighting wildfires with water in California may be so yesterday. The ranching family scion ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical substances. In Applied Physics Letters, by AIP Publishing, researchers from Nanjing ...

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 ...

Sound needs a medium (solid, liquid, or gas) to travel. Space is a vacuum, lacking the matter to carry sound waves. No sound in space means no echoes. While a near-perfect vacuum, some sounds can be ...

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 ...

Insights into how mixing layers scatter sound waves could further understanding of acoustic sources in open-jet wind tunnel ...

SAN DIEGO -- The early universe rang with the sound of countless cosmic bells, which filled the primordial darkness with ripples like the surface of a pond pounded by stones. The wave fronts later ...

This morning, scientists from the Laser Interferometer Gravity Observatory announced that LIGO had detected gravitational waves from the collision of two black holes, an event so cataclysmic that it ...
