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

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.

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

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 ...

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

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 ...

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 ...

A stellar concert is playing out in the night sky, and scientists are learning how to listen to it like never before. Deep inside stars, sound waves move through hot gas, creating vibrations. These ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.
