By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

But how do they actually work? You've probably seen noise-cancelling ... Let's go back to those sound waves from before. See, sound waves, like light waves, have peaks and valleys.

Using an air vortex cannon to focus the sound waves from the bass reflex port, it ‘wiggles’ the flame out in a matter of seconds, as illustrated with a thermal camera. Compared to the much ...

Directing sound to a specific location is difficult because of how sound waves behave. As vibrations move through the air, ...

A new paper explains how signals oscillating at complex-valued frequencies could transform sensing, imaging, and ...
