“Tinnitus is when you experience ringing or other noises in one or both of your ears. The noise you hear when you have tinnitus isn’t caused by an external sound, and other people usually can’t hear it. Tinnitus is a common problem. It affects about 15% to 20% of people, and is especially common in older adults. For many people, tinnitus improves with treatment of the underlying cause or with other treatments that reduce or mask the noise, making tinnitus less noticeable.”
