Tinnitus has many causes. Most of them are avoidable but some (antibiotics) less so.
People's ability to internalise a coping mechanism also varies. My own ability rises and sets like the tide. Some days it's all encompassing and some days it's just the liveness check for the nuclear storage tank alarm which reassures me I'm not dead yet.
White noise can help. Tuned noise can help. Other sounds can help. Apple ipods are said to help. It's all subjective. Do you want to test a rather odd mouth fitted electrode plate and a series of tuned sounds? It might help, and is being licenced with Food and Drugs.
Seeing "the Who" live in Glasgow twice in the 70s probably triggered mine. Or a number of other over-amped gigs. But my GP assured me the drugs for blood pressure, or antibiotics, or any number of situations were just as likely or what is known as "idiopathic" which is Latin for "who knows"
My partners tinnitus is much more intrusive and causes her more grief, since she now misses much ambient bird song lost in the ear soup. Beyond commiserations there isn't much I can say, inside my own kilohertz whine sound bath.
