My grandfather began going to lose his hearing in his mid 30s and was completely deaf by 40. He didn't know why or anything really about it. We weren't close and neither were he and my father. I am 32 and lately I have had a lot of trouble understanding my students. I find that I am asking them to repeat things 3, 4, or 5 times. I went for a hearing test and they say nothing is wrong but it seems to be getting worse. My boyfriend also complains that the TV is loud and now I feel like I need to concentrate on some the mouths of some of my students when they are talking. Also if I am in a crowded restaurant I feel like I miss half the conversation. On occasion I also hear high pitched noise in my right ear. Is it possible that I am losing my hearing and should I go for a second opinion? Also what would cause me to have these problems at such a young age?
