Former elementary school teacher Matt Shurtleff — known to many students as “Matt the Mad Scientist” — demonstrated how sound waves move using water and lasers.

Physically, sound is just pressure moving through a medium. If you harness that pressure correctly, you can actually push things around using nothing but sound. That's exactly what researchers at ...

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 ...

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 ...

Imagine three people huddled in a circle so when one speaks, only one other hears. Scientists have created a device that works like that, ensuring sound waves ripple in one direction only. The device, ...
