Ultrasonic cleaning uses sound waves that exceed the human auditory frequency to act on the cleaning fluid to achieve a series of physical and chemical effects. Since its operating frequency exceeds the human audible threshold, most people do not feel its effect; generally we listen. It is the sound produced by resonance of the external components such as the water tank. These sound frequencies are half or less than the operating frequency of the ultrasound; this part of the noise is human can hear.
Under normal circumstances, the effect of a well-designed ultrasound system on human hearing or human body can not be considered. For some devices with higher power or lower frequencies, it can generally be solved by closing the working environment and wearing anti-noise headphones.
