In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...

We've already seen sound waves do some pretty amazing things. For example, they can turn a regular, boring stream of water into a mesmerizing work of moving art, and even cause small particles to ...

Scientists from the University of Chicago and the University of Bath used sound waves to levitate particles, revealing new insights about how materials cluster together in the absence of ...

Conventional wisdom in physics dictates that sound waves are massless fluctuations in pressure that travel through materials like air, water, and eardrums — and can’t travel through empty space.

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 ...

Newly-developed acoustic technologies used to move particles and create haptic feedback in mid-air have stirred the imagination of many researchers. Unfortunately, the complexity of the equipment ...

Scientists have used sound waves to levitate particles, revealing new insights about how materials cluster together in the absence of gravity -- principles which underlie everything from how molecules ...
