From Wikipedia:
  The ear is the sense organ that detects sounds. The vertebrate ear shows a 
common biology from fish to humans, with variations in structure according to 
order and species. It not only acts as a receiver for sound, but plays a major 
role in the sense of balance and body position.
  Sound is a disturbance of mechanical energy that propagates through matter as 
a wave. Sound is characterized by the properties of waves, which are frequency, 
wavelength, period, amplitude, and speed.
  Humans perceive sound by the sense of hearing. By sound, we commonly mean the 
vibrations that travel through air and are audible to people. However, 
scientists and engineers use a wider definition of sound that includes low and 
high frequency vibrations in air that cannot be heard by humans, and vibrations 
that travel through all forms of matter, gases, liquids, solids, and plasmas.
  The matter that supports the sound is called the medium. Sound propagates as 
waves of alternating pressure, causing local regions of compression and 
rarefaction. Particles in the medium are displaced by the wave and oscillate. 
The scientific study of the absorption and reflection of sound waves is called 
  Noise is often used to refer to an unwanted sound. In science and 
engineering, noise is an undesirable component that obscures a wanted signal.

But Philip, a tree makes a noise when it falls in the forest regardless of 
whether there are human witnesses. This is the essence of truth.
