Power of Natural Ore: Modern man cannot leave Nature behind


❖Ultrasonic sounds are sound waves with frequencies higher than the upper audible limit of human hearing. (Ultrasounds)

❖Ultrasonic sounds are possible to use in many areas, but humans cannot hear it.

❖Ultrasonic sounds are defined as sound at frequencies greater than 20KHz. ( The upper frequency limit in humans is approximately between 20Hz to 20 KHz)

❖Decibel is a unit of measure used for amount of audible sound. Hertz is a unit of measure that is used for the frequency of sound.

❖Ultrasonic sound is high in directivity. Used properly, ultrasonic sound is able to provide high-resolution images in many fields: industrial sensors, medical examination/treatment, industrial nondestructive inspections, fishing sonars and depth sounders.

❖As sound pressure is relatively easy to amplify, ultrasonic sound can be used in many ways: noiseless drills, welding, polishing, sterilization and cleaning of metal and plastic, specialty speakers, humidifiers, small motors, remote control communication, and bone conduction speakers. communication speakers, and countless other applications.

❖Bats and dolphins use ultrasound to guide movements and source food.

Main operational frequencies in industrial equipment

[Ultrasonic cleaning] 20KHz~200KHz、500KHz~over 1MHz
[Ultrasonic welding] 50KHz~200KHz(1W~50W)
[Ultrasonic humidifier] about1MHz
[Ultrasonic flaw detector/Ultrasonic thickness meter] 100KHz~10MHz
[Collision avoidance system] 17KHz~19KHz
[Ultrasonic microscope] 100MHz~1GHz
