Question: It's not that I'm worried about it, or anything, I've just always been curious why every so often (a few times a month, maybe), a single ear of mine (fairly equally distributed, I think, between left and right) will ring, with a sort of high frequency pitch, for a few seconds, and then cease. Interestingly, I can occasionally tell it's going to happen, because the hearing in that particular ear will go quiet, just before the ringing starts.Any info?

Answer: Tinnutus

IntroductionRinging. Buzzing. Roaring. Whooshing. Chirping. Beating. Humming. While you may enjoy these sounds in nature, they're no fun when they're coming from inside your own head.

Head noise, or ringing in your ears (tinnitus), is common. Millions of people have some degree of tinnitus. For some of them, the ringing in their ears is distressing enough for them to seek medical help. But, tinnitus isn't a disease. It's a symptom that can be caused by a number of medical conditions. Tinnitus may be the result of age-related hearing loss or ear injury, or it may be an indication of a disease of your circulatory system.

Most people find that by taking steps to reduce or mask the noise or by treating its underlying causes, their symptoms improve over time. And although the noise of tinnitus may be annoying, the condition rarely is a warning of a serious problem.
