In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.he mechanical vibrations that can be interpreted as sound are able to travel through all forms of matter: gases, liquids, solids, and plasmas. The matter that supports the sound is called the medium. Sound cannot travel through a vacuum.
Sound energy. Sound is the movement of energy through substances in longitudinal (compression/rarefaction) waves. Sound is produced when a force causes an object or substance to vibrate â the energy is transferred through the substance in a wave.Typically, the energy in sound is far less than other forms of energy.Let's see this illustration. A vibrating drum in a disco transfers energy to the room as sound.ound is produced when a force causes an object or substance to vibrate â the energy is transferred through the substance in a wave.
