Abstract :
High power low frequency ultrasonic systems used in sonochemistry, for cell disruption or sonophoresis are usually calibrated and controlled with procedures (electrical power measurement, calorimetry, chemical dosimetry) that just give an indication about performance. The surface vibration amplitude, both in air and in water of a high power low frequency ultrasonic system, is determined by laser interferometry combined to calculation. A good agreement was found between simulations and experiments. Finally, the system acoustic power output in water is determined precisely
