The field of ultrasonic is still making strides towards perfection, but already many applications of ultrasonic energy have been found in science and technology. Ultrasonics is the science of sound waves above the limits of human audibility. This article is describing the theory of ultrasonics, how ultrasonic technology is applied to precision cleaning and how cavitation, acoustic streaming and dislocation motion during the propagation of high-intensity ultrasound are making the cleaning of the substrates immersed in to the bath.
Key Words: Ultrasound, sonochemistry, transducer, cavitation
