ultrasonics
Vibrational or stress waves in elastic media that have a frequency above 20 kilohertz, the highest frequency of sound waves that can be detected by the human ear. The waves may be longitudinal (as in air or solids) or transverse (as in liquids). They can be generated or detected by piezoelectric transducers (see piezoelectricity). High-power ultrasonics produce distortion in the medium; applications include ultrasonic welding, drilling, irradiation of fluid suspensions (as in wine clarification), cleaning of surfaces (such as jewelry), and disruption of biological structures. Low-power ultrasonic waves do not cause distortions; the uses include sonar, structure testing, and medical imaging and diagnosis. Some animals, including bats, employ ultrasonic echolocation for navigation
the application of ultrasonic energy to do work (specifically as opposed to subsonic, supersonic, or transsonic, q v )
the science and technology of ultrasound
{i} branch of science dealing with phenomena having a frequency above the range of sound audible to the human ear
Very high frequency sound waves, over 18,000 vibrations per second, traveling through a liquid in which parts are immersed for thorough cleaning
the technology associated with the use of sound above 15 kHz Applied to thickness, density, flow and level sensing Also used for imaging
