Tinnitus, often referred to as a ringing in the ears, is the perception of sound when no external sound is present. It’s not a condition in and of itself, but rather a symptom of some other problem in the auditory system.
Tinnitus is generally classified into two categories: objective and subjective. Objective tinnitus is tinnitus your doctor can hear with a stethoscope or sometimes by simply listening in close proximity to your ear. This kind of tinnitus is rare, accounting for a small percentage of all tinnitus cases. Subjective tinnitus, on the other hand, is tinnitus only you can hear. Most people who experience tinnitus have subjective tinnitus.
