Researchers develop an innovative sound wave sensor to quickly and accurately detect elusive helium gas leaks, enhancing ...

A team of researchers from the Ministry of Health in Kuwait has successfully demonstrated the destruction of SARS-CoV-2 virus ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

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.

The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.

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 film explores the origins of sound through three primary sources: vibrating columns of air, vibrating surfaces, and vibrating strings. It demonstrates how sound is produced by examining a tuning ...

Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that ...

At University College London, Lesley sings I Dreamed a Dream inside an MRI scanner to reveal how her vocal tract acts as a ...

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 ...

Create a focused speaker so your music targets only the listener. That demodulates at 40 kilohertz, with an H-bridge and ...

Inspired by the functioning of pulsed lasers, scientists from France and Japan have developed an acoustic counterpart that enables the precise and controlled transmission of single electrons between ...
