Insights into how mixing layers scatter sound waves could further understanding of acoustic sources in open-jet wind tunnel ...

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 ...

Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

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 ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

NASA has recently transformed sound waves emanating from the Perseus Galaxy Cluster’s black hole into a format perceptible to the human ear, offering a unique auditory glimpse into the universe’s ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Ten years ago this month, gravitational waves were first detected on planet Earth. Now, gravitational waves had been something that scientists had thought existed going back to Albert Einstein. His ...

Surfers have taken to the ocean for centuries. Ancient Polynesian civilizations were surfing as far back as 2,000 BC, and there is evidence of wave riding in 12th-century Hawaii. Of course, back then, ...
