Gravity overcome. Sound waves let objects hover

British researchers have developed a machine, which lets objects hover on sound waves. 64 mini loudspeakers form a kind of sound field for it, on which objects can be controlled three-dimensionally in the air. Since sound waves also penetrate tissue, medicine for example could be moved through the body without surgical intervention.

Sound The sound waves generate an acoustic hologram on which the objects hover.

A research team of the Universities Bristol and Sussex have developed a machine, which brings things to hover by means of sound waves. By means of a Sonic Tractor Beam the hovering objects can also be directly moved and controlled in the air.

The sound out of 64 mini loudspeakers makes this possible, which can produce a kind of hologram out of highly precise adjustable sound waves, on which the objects hover. The holographic illusion can so be produced that for example a hovering hand holds and moves the objects freely in space, as the science blog iflscience reports. Up to now no men can however hover on the sound waves, but only objects of up to 4 millimetre diameter.

The sound waves have the advantage that they can overcome not only gravity but also all tissue and even walls. A potential area of application the researchers therefore see in the human body, as they explain to a publication in the specialist magazine Nature. The tissue penetrating power of the sound waves could therefore be used to move medical objects like medicines or kidney stones in the body from the outside, without having to open the body surgically with it.
