    Ultrasounds are mechanical waves that propagate through a medium by vibrating particles in the form of compressions and rarefactions. Specifically, they are a type of longitudinal wave, where the oscillations occur parallel to the direction of wave propagation. Ultrasounds have frequencies above the human audible range, typically exceeding 20,000 hertz.
