Ultrasonic levitation is a phenomenon of capturing an object at the position of the node of the sound pressure of the standing wave. The purpose of our research is to measure the Young's modulus of the levitated thin film at the node of the sound pressure of the standing wave generated between the Langevin transducer and the reflector facing it. In order to measure the Young's modulus of the levitated thin film and compare it with the theoretical value, it is necessary to quantitatively evaluate the behavior of the levitated thin film. First of all, as a simple model, experiments are conducted on the relationship between the sound pressure of the levitating position and the levitating position of the object, as a target of levitation of a spherical Styrofoam instead of a thin film. Then, the same experiment is carried out by inverting the position where the Langevin transducer and the reflector are fixed, and the phenomenon of the levitation of the object and the phenomenon of the acoustic streaming are compared.
