What is the DB level of ultra sonic sound?

Ultrasonic sound refers to sound waves with frequencies above the human hearing range, typically above 20 kHz. The decibel (dB) level of ultrasonic sound can vary significantly depending on the source, but it is often measured in the range of 80 dB to over 120 dB. However, since humans cannot hear ultrasonic frequencies, their impact is typically evaluated in terms of their effects on materials or biological systems rather than their perceived loudness.
