Sound is a fundamental element in life for almost all humans and animals.  So many things can be accomplished with sound.  Music, one of the most important art forms, can be played hundreds, even thousands of different ways by manipulating sound.  Our main form of communication is talking and listening to others speak.  Sound can be explained through waves in a wave tank or through waves on a spring.  All forms of waves have certain characteristics, which make sound waves no different than water waves created in a wave tank or waves created on a spring.  These waves are simply different forms of energy, but all have intrinsic properties that make them similar.  Like any waves, two sound waves can exhibit interference and can make the sound louder or cancel the sound out.
The phenomenon of a guitar string is a very good example of waves on a spring and standing waves.  A guitar string is a standing wave because the string is fixed at both ends and can vibrate.  The speed of the waves of a string depends on the tension and mass.  Since the fundamental wavelength of a standing wave on a guitar string is twice the distance between the bridge and the fret, all six strings use the same range of wavelengths.  The different pitch of the string depends on the wave speed.  But if the strings all had different tensions it would be very hard to play, therefore if the guitar strings are roughly the same tension then the strings must be different masses.  This is why the lower strings have a higher mass; they are made thicker by wrapping them in wire.  This makes the guitar easier to play.
Communication with other life, without sound, would be much more complicated.  The physics of communication is through talking and through hearing.  The human voice is created from the larynx located in the throat.  A different pitch of sound depends on how the larynx is manipulated.  We hear these manipulations by using our ears, whether we wa...
