A team of researchers co-led by the University of California San Diego, University of Michigan, and the French National ...

This array of piezoelectric sensors is designed to install in theaters and concert halls to harness sound wave energy to create electricity. This miniature proof of concept included 1,042 sensors, and ...

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side ...

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.

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.

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

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 ...

NASA astronaut [Don Pettit] shared a short video from an experiment he performed on the ISS back in 2012, demonstrating the effects of sound waves on water in space. Specifically, seeing what happens ...

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 ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...
