Although there are many reasons sound is important; a couple reasons are that it allows humans and animals to hear and communicate, and it is a primary component in the functioning of sonar equipment. Sound occurs in a variety of waves, which have different characteristics and produce different types of noises.

Sound waves are among the most basic and common sound waves. There are two types of sound waves, which are transverse and longitudinal waves. Transverse waves are typically produced by electromagnetic devices and objects, such as light, radio and television. Sound can also exist as longitudinal waves, which are produced by mechanical vibrations in machinery and industrial equipment.
