Tinnitus involves the sensation of hearing sound when no external sound is present. According to the Mayo Clinic, it's a fairly common problem, affecting about 15 to 20 percent of people. It can be caused by an underlying condition, such as age-related hearing loss or injury to the ear, but it's usually not a sign of something serious.

Most people have experienced some form of tinnitus, however short lived it may be. Attending a loud concert or watching a loud movie can trigger tinnitus that fades away after several hours. If the condition persists for over six months, it is then considered chronic tinnitus, a condition which usually requires medical diagnosis. While more rare, effects of chronic tinnitus can be greatly reduced or eliminated by a variety of treatments.

Our ears are complex organs that allow us to take in many stimuli at once. They are always collecting information -- even when you’re asleep! The ears contain some of the smallest, most delicate bones in your body. While these bones are small enough to fit on a penny, their structure and the surrounding valves have evolved to support the sensory neurons responsible for the sensation of hearing.
