The acoustic radiation force has been used in many engineering applications and devices. Good performance of these applications require faithful reproduction of the designed wave field in the device. However, mapping out the wave field using current techniques, such as hydrophone measurements, is challenging. This work demonstrates that the trajectories of the transient motion of microspheres moving to their equilibrium positions within a standing wave can be used to calculate the wave amplitude.The acoustic radiation force has been used in many engineering applications and devices.
