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 have demonstrated how floating particles will assemble and synchronize in response to acoustic waves. Their simple experiment provides a new framework for studying how seemingly lifelike ...

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 ...

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 ...

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 ...

The interference of sound waves is not just of academic interest. For instance, it is the operating principle of noise-cancelling headphones. These create their own sound vibrations, which are tuned ...

An elegantly simple experiment with floating particles self-assembling in response to sound waves has provided a new framework for studying how seemingly lifelike behaviors emerge in response to ...
