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 ...

In holographic direct sound printing, a transducer emits high-acoustic pressure sound waves, inducing a sonochemical reaction called cavitation that creates solid material inside the build chamber. A ...

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.

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 ...

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 ...
