Sound is the consequence of the vibratory movement of a body, which when vibrating generates waves that propagate through an elastic medium such as air. It should be clear that in the production of sound there is transport of energy, without any movement of matter.
Sounds are perceived by the sense of hearing, this largely depends on the frequency of the vibration.
The human being. It cannot pick up vibrations with a frequency of less than 20 Hz, nor more than 20,000 Hz, so those between these two values are perceived.
