I've had mild tinnitus for about 2 years now. As you say it's a quiet rustling/hissing sound but it's continual (24 hours/7 days) and fortunately it does not interfere with my quality of life.

I dunno why it started - loud noise is unlikely as I don't go to noisy places, not do I play my CDs loud. Another of Life's Little Mysteries.

Mo, you know what is setting you off, so please follow the advice given above & keep away from aggrevating noise cos you wouldn't want the really bad ringing that drives some folk crazy.
