What is an

 

Ultrasound is understood as sound waves, whose frequency is above the threshold of human hearing ,the range is between16 kHz - 1 GHz). In addition, you can generate ultrasound with much higher energy, ie, much "louder" than the audible sound. In the use of ultrasound technology distinguish the weak signal (test materials, medical supplies, diagnostics) and high-intensity ultrasound, such as ultrasound for cleaning, ultrasonic welding. Applied to liquid media ultrasound has found application in the so-called effect of "ultrasonic cavitation." This effect is used as a basis in the ultrasonic cleaning device.
