Tinnitus or ringing in the ears is defined as the sensation of hearing whistling, chirping, hissing, buzzing, ringing, or other sounds. The noise can be continuous or intermittent and can differ in loudness. It is usually worse when there is low background noise, so people are more aware of it at night when trying to fall asleep in a quiet room. In some rare cases, the noise occurs simultaneously with the heartbeat, a condition known as pulsatile tinnitus.

Tinnitus is very widespread. In fact, it affects approximately 50 million adults in the United States. For many people, tinnitus is simply an annoyance. However, in severe cases, the condition may cause people to have difficulty in sleeping or concentrating. The condition may even interfere with personal relationships and work, leading to psychological stress.
