Processing and Power
High-power applications of ultrasound often use frequencies between 20 kHz and a few hundred Khz. Power densities can be very high; above 10 watts/square centimeter, cavitation can be inducted in liquid media, and some applications use up to 1000 watts per square centimeter. Such high power levels can induce chemical changes or produce significant effects by direct mechanical action, and can inactivate harmful microrganisms.
