At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

Soil is one of our most precious resources. Ecoacoustics, or the study of environmental sounds, has been around for a century, but it has only recently been applied to understanding soils. This ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...

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 ...

In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave -- including halting fat development. Forget fad diets and sketchy supplements, your favorite ...

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 strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating cycles, even without a steady external push.

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a ...

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 ...
