Sound is actually an energy wave of molecules that create a vibration. Sound can travel through and bend around many objects, including water. Check out how sound works: 1  When an object moves it creates a vibration. 2  Vibrations move air particles around. 3  These moving particles are constantly bumping into each other. 4  Our ears can pick up these particle-vibrations as sound. 5  Fast moving particles create a high sound, while slow ones are low-sounding.
