Researchers have come up with a new and improved way to levitate objects using sound waves alone, an impressive feat of mixed-reality technology that could pave the way for some seriously futuristic hologram-like displays.
As seen in a new video, the researchers were able to levitate individual polystyrene beads and water particles inside a special enclosure, making them move in three dimensions by adjusting the output of hundreds of small speakers, set up in a grid.
In one demonstration, they were even able to float a tiny piece of fabric in midair, on which they projected a movie of a leaping rabbit.
The team also addressed a fatal flaw with a previous iteration of their work. By increasing the number of speakers to 256 and adjusting each of their outputs using sophisticated software, the researchers were able to move the object despite the presence of interference.
Scientists Are Getting Better and Better at Levitating Objects With Sound Waves

I truly believe we do not study sound waves enough. So much energy going into the physics of quantum theory and basic stuff and not enough into some real serious not so new techniques that might be further developed and not so much new things. Balance. Sound waves are overlooked too much.
