Acoustically induced cavitation at 20 kHz is observed by means of high speed video recording. Using digital image processing the bubbles' trajectories are investigated. The data reveals a complicated near field interaction between the bubbles. A dominant phenomenon is the collision and coalescence of bubbles, even in the relatively sparse populated streamers.
