- Ultrasound - Wikipedia
An ultrasonic examination Ultrasound 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 Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz Ultrasound is used in many
- Ultrasonics | Physics, Sound Waves Applications | Britannica
Ultrasonics, 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
