Tinnitus is the medical term for the sensation of hearing sounds in your ears or head when no external sound is present. People who suffer from tinnitus typically describe the sound as "ringing in ears," though others describe it as hissing, buzzing, pulsing, roaring and even chirping.
According to the American Tinnitus Association (ATA), 50 million Americans experience tinnitus (nearly one in six of us). For some, tinnitus is mild and an intermittent annoyance. For others, it's severe and can have a profound effect on their quality of life. But for everyone, finding tinnitus relief is a high priority.
