ELI5:  Why do I hear an annoying high- pitchedbeep/buzz in my ear?

This only happens occasionally and when it does, I usually feel some sort of change in the pressure in my ears and then a fairly high pitched and steady frequency that drones on for maybe a minute.  Then it goes away.

Your ear has thousands of little hairs which vibrate and send signals to your brain. Your brain then interprets those signals as sound.  Sometimes the little hairs can go a temporarily "haywire" and send a jumble of signals that your brain interprets as the buzz or whine.  While a constant noise is cause for a concern, a short little burst can be caused by a cold, ear wax, stress, or a bit of dirt or hair bumping against your ear drum.
