Sound is a wave that travels through a medium and carries energy from one place to another. A sound wave consists of a series of orderly oscillations of particles within the medium. These oscillations produce regions of compressions and rarefaction (high and low pressures) throughout the medium. Ultrasound is defined as a sound wave with a frequency above 20,000 cycles per second or hertz (Hz).
