In this study, the translational trajectory of bubble in an ultrasonic standing wave at 22.4 kHz was observed using an imaging system with a high-speed video camera. This allowed the velocities of bubble be measured when the acoustic pressure at 20 kPa, 40 kPa and 60 kPa, which applied to indirectly measured the history force by using the acoustic and hydrodynamic forces balance model. It shown that bubbles driven at low acoustic pressure, the history force close to zero, and with the pressure increase the history f
