Sound! It’s a thing you hear, moreso than something you see with your eyes. And yet, it is possible to visualize sound with ...

Using sound to get objects to float works well if a single particle is levitated, but it causes multiple particles to collapse into a clump in mid-air. Physicists at the Institute of Science and ...

Like an invisible pair of tweezers, sound waves can be used to levitate tiny objects in the air. While DIY acoustic levitation kits can be found online, the technique has important applications for ...

Researchers in Tokyo have put a new twist on the use of sound to suspend objects in air. They've used ultrasonic standing waves to trap pieces of wood, metal, and water – and even move them around.

A study on the levitation technique titled "High-speed acoustic holography with arbitrary scattering objects" has been published in the journal Science Advances. Researchers from the University ...
