Stylolites — irregular seams that occur in limestone — have been found to affect how acoustic waves move through rock samples. Laboratory-based insights from KAUST researchers offer an improved ...

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 ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...

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 ...

Imagine three people huddled in a circle so when one speaks, only one other hears. Scientists have created a device that works like that, ensuring sound waves ripple in one direction only. The device, ...

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 ...

Interactive sound propagation in virtual environments represents an interdisciplinary frontier where computational acoustics, real-time processing and immersive media converge. This field investigates ...

The long-standing mystery around why spider webs sometimes feature "extra touches" known as stabilimenta has been revisited in a new study which suggests that their wave-propagation effects could help ...
