Tinnitus is known as ringing in your ears, but sufferers can tell you this often annoying, sometimes debilitating problem can manifest as hissing, clicking, or sound like the roaring of ocean waves.
Why does tinnitus happen? This hearing of phantom sound still mystifies many researchers, but there are clues that it may be a symptom of some age-related diseases, can be the result of age-related hearing loss, or a consequence of long-term exposure to loud noises. It's so common among musicians that a non-profit organization, "Hearing Education and Awareness For Rockers" or HEAR, was established in the late 1980s to help with this particular occupational hazard. Since then, San Francisco co-founders Kathy Peck (a rock musician) and Flash Gordon (a local physician) have helped thousands of sufferers better understand and cope with this difficult problem.
Legendary rock guitarist Pete Townshend of the Who - who also suffers from tinnitus - is a supporter of the education effort.
