A few years ago, a team of MIT scientists developed a novel way to separate blood cells using sound waves. Now the team, in conjunction with scientists from several other institutions, has taken the ...

Sound is everywhere, but what if certain frequencies could actually change how your body feels? From vibrations that make you ...

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.

In holographic direct sound printing, a transducer emits high-acoustic pressure sound waves, inducing a sonochemical reaction called cavitation that creates solid material inside the build chamber. A ...

Yale scientists used laser light to gain access to long-lived sound waves in crystalline solids as the basis for information storage. The result was published online April 2 in the journal Nature ...

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 ...

Expertise from Forbes Councils members, operated under license. Opinions expressed are those of the author. At the start of my career, I used to do acoustic testing in an anechoic chamber where sound ...

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 ...

Sound waves traveling thousands of kilometers through the ocean may help scientists monitor climate change. As greenhouse gas emissions warm the planet, the ocean is absorbing vast amounts of that ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...
