No smoke, no mirrors, just sound was all scientists needed to levitate objects in midair. NPR reports that researchers at the University of Tokyo have discovered a new levitation technique through ...

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 ...

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

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 ...

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 ...

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 ...

This Pyro Board takes the general concept of a Reubens’ tube, an antiquated tool that was previously implemented when demonstrating a visual for standing waves, and makes it look like wizardry. The ...

Yun Jing receives funding from NSF. Jiaxin Zhong does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed ...

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on ...
