Abstract
We present a new virtual laboratory developed with COMSOL multiphysics for the simulation of an acoustic levitator, as well as a three-dimensional (3D) printed experimental setup. Our software application simulates the acoustic pressure field and its interaction with a set of particles. Students can interact with the system having the possibility to change the frequency and distance parameters between transducers in real time. We have also developed and shared for free use the 3D printing design files for the construction of the necessary components for the acoustic levitator, as well as the instructions for its experimental implementation. The experimental results are contrasted, along with those from the virtual laboratory, providing students with useful tools to understand and interpret the acoustic phenomenon in question.
