Hi, so today at school I was at class and a bunch of kids were screaming and talking, laughing. Suddenly, in my left ear I heard kind of a beep, or a ringing noise. No It wasn't a car horn, and no there weren't workers from Walmart ringing bells outside. I shook my head and It went away. Doesn't It usually happen to you, your normal and suddenly you go deaf for a couple of seconds in one ear. Could this mean something?Thank you
