ultrahelile
Ultrahelile refers to sound waves with frequencies higher than the upper audible limit of human hearing, which is typically around 20 kilohertz (20,000 Hz). These high-frequency sounds are generated by a variety of natural and artificial sources. In nature, insects like bats and dolphins produce and utilize ultrasound for echolocation, navigating their environment and hunting prey. In the human-made world, ultrasound technology has found numerous applications. Medical imaging, known as ultrasonography, uses ultrasound waves to create visual representations of internal body structures, playing a crucial role in diagnostics for pregnancy, organ examination, and more.
Industrial uses include non-destructive testing of materials to detect flaws or cracks without damaging the object.
