Ultrasound
Diagnostic ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasound 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).

Development and Justification of Treatment and Modification
It is proved that after crushing and grinding, exposure to ultrasound, drying, screening and dedusting, zeolite rocks with a particle size of more than 0.1 mm were concentrated on a 138-TSE electromagnetic separator, with a particle size of less than 0.1 mm—on a SIM-1 separator (see Tables 2 and 3).

Nature and Biophysical Effects of Ultrasound
The quartz plate is a vibrating plane from which ultrasound waves are emitted in a per-pendicular direction. They form a wave bundle with an angle of spread of about 6° to the sides. The larger the quartz plate, the greater the cross-section of the bundle. Intensity of ultrasound diminishes with the square of the distance from the plate, and also

What do the rocks say? lab edition | MIT Department of Earth
Using ultrasound sensors, MIT researchers eavesdrop on the internal sounds of squishing rocks to reveal how rocks fracture and flow within the depths of the Earth. Deep inside the Earth, the rocks are singing. The intense heat and crushing pressure below the Earth ’ s surface causes rocks to deform – to crack, flow, fracture, and melt.
