Sound ['saund]
Vibrations that can be heard when they reach the ear of a person or animal.

Sound is a kind of energy created when something vibrates. When this vibration reaches an ear, it is translated into what we recognize as a sound. Sound waves travel through matter, such as air, water or even furniture, until their energy runs out and the molecules stop moving. We hear different pitches, such as the notes from a musical instrument, because sound waves vibrate at different frequencies.
