Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

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 ...

Sound is usually something we hear, not something we touch. But researchers at Virginia Tech have found a way to turn ...

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 ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

The clue to the answer is in the second part of the question, which mentions “various frequencies”. In 1822, French mathematician and philosopher Joseph Fourier effectively proved that every sound can ...
