Tinnitus is the sensation of sound when there is no auditory stimulus (Kumar and Clark).  The sound can be anything from a ringing to a hissing, humming, whistling, clicking or roaring noise.  


Tinnitus is not a disease but more a symptom.  Tinnitus can be a symptom of wax build up in the ear, a foreign object in the ear or damage to the ear from loud noises.


In regards to loud noise tinnitus can be caused by prolonged exposure to noise of over 70 dB.  This prolonged loud noise cause minute hairs in the inner ear to vibrate.  Prolonged vibration can alter the neural feedback going from the ear to the brain giving the impression of a ringing noise when there is no noise at all.


The best was to prevent tinnitus is to wear ear plugs when exposed to loud noises.  Also turning down the volume on your iPod can prevent future damage to your ears.

Lars Ulrich, Ludwig van Beethoven and David Letterman all suffer from tinnitus.  No one is immune from tinnitus!
