Acoustic Levitation Explained Acoustic levitation is a technique that uses sound waves to suspend objects in the air without any physical support. By generating ultrasonic sound waves, which are beyond the range of human hearing, standing waves with alternating high and low-pressure regions are created. Objects can be trapped at the nodes of these standing waves, where the pressure is minimal, balancing the gravitational force with the acoustic radiation pressure. This allows for stable levitati
