In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can greatly affect how sound waves travel from one point to another. Mesoscale ...

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 ...

Scientists at Japan’s Nagoya University have used Japan’s extensive network of GNSS receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake.

A University of California scientist working at Los Alamos National Laboratory and researchers from Northrop Grumman Space Technology have developed a novel method for generating electrical power for ...

Summer is the season of sound in Chicago: from fireworks to car stereos, the jingle of paleta carts to outdoor concerts. But hearing a concert from over four miles away? That’s exactly what happened ...

Sound needs a medium (solid, liquid, or gas) to travel. Space is a vacuum, lacking the matter to carry sound waves. No sound in space means no echoes. While a near-perfect vacuum, some sounds can be ...

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.

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 ...
