This is the title of an Ernest Hemingway novel (1940) that later became a popular movie. It tells the story of Robert Jordan, a young American in the International Brigades attached to an anti-fascist(Republicans)guerilla unit during the Spanish Civil War.
The Novel's title comes from a famous quotation of John Donne (1624); it goes like this:
"No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee."
Tinnitus is usually described by sufferers as a perceived sound of a ringing noise. I just wonder if Quasimodo suffered from this malady.
