There's a YouTube video that's shows the effect:

PeterO said:Don't forget that sound is a longitudinal wave, so rather than "shaking" the air, between the horns, from side to side, it moves it up and down. I assume the "levitated" styrene balls stabilise themselves at a displacement node, where it is calm, a bit like the sand on those Chladni plates.

Awesome Sonic Levitation is a scientific phenomenon where an object or substance is suspended in mid-air using sound waves. It is also known as acoustic levitation.
Awesome Sonic Levitation uses sound waves to create a standing wave pattern that produces nodes and antinodes. The nodes are areas of low pressure, while the antinodes are areas of high pressure. The object or substance is then trapped in the antinodes, effectively levitating it.
Awesome Sonic Levitation can be used to levitate a wide range of objects and substances, including liquids, solids, and even live animals. The only requirement is that the object or substance must have a density lower than that of air.
Awesome Sonic Levitation has a variety of potential applications in different fields, such as pharmaceuticals, chemical reactions, and material science. It can also be used for non-contact handling and transportation of delicate objects, as well as for creating 3D printing structures.
While Awesome Sonic Levitation has many potential applications, there are also some limitations. It can only levitate objects that are smaller than the wavelength of the sound waves being used. Additionally, precise control and stabilization are necessary for levitating objects for extended periods.
