Sound from ultrasound

ID: sound-from-ultrasound

Ultrasound is a type of sound wave that has frequencies above the range of human hearing, typically above 20 kHz. Sound, in general, is a mechanical wave that propagates through a medium (such as air, water, or solids) as a vibration of particles. The characteristics of sound, including its frequency, wavelength, and amplitude, determine its pitch and volume.
