Tinnitus and hearing loss: What’s the connection?
Roughly 15% of adults experience tinnitus, a ringing (or similar noise) in one or both ears, at some point in their lives. The sound may be steady or pulsating, and symptoms can come and go for some and be constant for others. While the cause of tinnitus is not always clear, we do know that it's often linked to hearing loss.
