Sound is the sensation that is produced when the longitudinal vibrations of molecules from the external environment hit the tympanic membrane. Such vibrations in the external environment are called sound waves. Sound waves are produced when vibrating molecules generate changes in pressure. The speed of sound waves in air is approximately 344m/s at 20 degrees at sea level. An increase in temperature and altitude increases the speed of sound. Other media conduct sound at different speeds. For instance, in fresh water, sound travels at a speed of 1450m/s. Sound can be referred in a perceptual response and a physical stimulus. Sound reaches ...

Human perception of sounds is not only performed by an ear as a part of the body. In fact, a person hears through the organ of hearing, which has got complex structure. The ear is only a visible part of it.
