So, what is the ultrasonic frequency? They are frequencies that the human ear can hear, usually 20,000 Hz or 20 kHz. The operating frequency of most ultrasound processes is 20 to 40 kHz. Some operating frequencies are 15 kHz, which is not technically within the ultrasonic range, but is still considered ultrasonic welding.
