Ultrasound Physics and Technical Facts for the Beginner
WEBUltrasound refers to any sound waves with frequencies greater than 20kHz. Diagnostic ultrasound typically uses frequencies between 2 and 20 million Hertz (Megahertz - MHz) The propagation speed of an acoustic wave traveling through a specific medium is determined by the stiffness of that medium.
Ultrasound - Wikipedia
WEBUltrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound.
Ultrasound - National Institute of Biomedical Imaging and …
WEBUltrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range). Most diagnostic ultrasound probes are placed on the skin.

WEBUltrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term sonic is applied to ultrasound waves of very high amplitudes. Hypersound, sometimes called praetersound or microsound, is sound waves of frequencies.
