30kHz
30kHz refers to a frequency of 30 kilohertz, which is 30,000 cycles per second. This frequency falls within the ultrasonic range, meaning it is above the upper limit of human hearing, which is typically around 20 kilohertz. Frequencies above 20 kHz are inaudible to humans.
Ultrasonic frequencies like 30 kHz have a wide range of applications due to their ability to travel
Another significant use of 30 kHz is in ultrasonic cleaning. Devices operating at this frequency generate cavitation
Furthermore, 30 kHz can be employed in industrial processes such as ultrasonic welding, where high-frequency vibrations
