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.
What is the difference between a loud sound and a soft sound? Sound is actually a vibration in the air which travels in the form of a wave. The larger the amplitude of the wave, the louder the sound. the smaller the amplitude of the wa â¦ ve, the softer the sound.
