-SKSONICWhen sound propagates, it is also accompanied by the propagation of energy. It is expressed as the energy per unit area (energy flow density of sound waves) passing through the direction perpendicular to the propagation of sound waves per unit time. The unit of sound intensity is watts per square meter. The magnitude of sound intensity is proportional to the speed of sound, and is proportional to the square of the frequency and amplitude of sound waves. The strength of ultrasound is due to its high frequency,
