Affecting as many as 40 million adults in the US, tinnitus is a ringing, roaring, or hissing sound in one or both ears without an external cause. The condition can be either objective or subjective. Objective tinnitus involves sounds that both patient and doctor can hear and is usually caused by turbulent blood flow through malformed vessels, tumors, or rhythmic muscular spasms. Most tinnitus cases, however, are subjective, meaning they involve sounds heard only by the patients. What causes it?
