✦ Synopsis

Acoustic levitation has been studied using airborne radiation from a high power magnetostrictive ferrite transducer of frequency 18 kHz. Spherical solid objects as well as liquid drops of varying weight and radii have been levitated under I G at the velocity antinodes of the standing waves formed with the help of a reflector. The dependence of the maximum weight of a spherical object that can be levitated on the sound pressure level and the radius of the obstacle has been studied. An attempt has been made to estimate the radiated high power sound intensity from the maximum weight of the spherical object that can be levitated.
