For as long as I can remember, I’ve always had spells (very rarely) wherein I could hear a very high-pitched whining noise in my left ear. Never in my right, always in my left. The sounds coming into my ear would drop dramatically in level, almost as if ceasing to exist at all, and then the whining noise would replace them, almost un-noticeably.
Sound, another sound like going underwater (without the splash) and then the whining.
I did some looking around (because if it’s happening to me, then it more than likely is happening to others) and came across an article that listed Tinnitus as being a possible cause for this.
One of the possible causes of Tinnitus was listed as “low levels of serotonin”, which is believed to play a part in mood, and is believed to be associated with many disorders, one of them being clinical depression.
Since I have already been diagnosed with this, I can only conclude that a possible cause for the ringing is tinnitus. However, being the diagnostician that I certainly am not, and being an American without health care (and no possibility of it unless we (ha!) get Universal Healthcare like so many of the counties that are smart enough to do this instead of just watching their citizens die in the street (more or less)), I can only say that this is a good guess and can not actually diagnose or confirm it.
