I was born hard of hearing. The degree to which I was hh is questionable, as while I know based on my experiences that if I'm hh now (and indeed my audiogram indicates I am), I've been hh my entire life. What is unknown is if my hearing has gotten much worse over the course of my life, something I don't know. While my last audiogram had the 8 kHz rating slipping to 90 dB, nothing else has changed in any noticable way since my first audiogram at 17 (great low-frequency hearing, bad to nonexistant high-frequency hearing). Hard to say if it has always been this way, but nonetheless...
My parents were either oblivious to the fact that I couldn't hear or feigned ignorance of it, which is the reason I was not diagnosed until I was 17. (Now 19.) They acted as if it were my fault at first, that I never told them that I was having difficulty understanding speech (I did, the just countered with the denial things that most hearing people going deaf say about themselves). After I said I wanted to start wearing a hearing aid (really need two, but can only afford one), my parents have slowly come to accept that I'm hh and deal with it. They never let me have CC on if they were in the room before if the show/movie/etc. was in English, but now they don't mind (or if they do, they don't prevent me from using it because they understand that I can't understand all of what is being said).
Concurrently, I've had to come to terms with the fact that I am hh, something I was in denial of for almost as long as they were. It's hard when you're raised hearing, even if you were hh the whole time because for a long time you just can't accept that you're not hearing anymore (or, as in my case, never were to begin with). You get depressed because you think that you're disabled, because hearing people are raised to believe that being deaf is wrong; deafness is a disability and whatnot.
If I didn't go to RIT/NTID, I would probably not have a hearing aid now and I probably would not have the acceptance of myself as a hard of hearing individual that I have now as a result. The presence of the RIT/NTID deaf population has in many ways opened my eyes. It has enabled me, simply by being present, to come to terms with my hearing or lack thereof. It has enabled me to learn a new language, to make new friends and to accept an aspect of myself that I would not otherwise have come to terms with as quickly. I don't love RIT for it's academics, or for the food or for its reputation factor on my resume, or its staff or my friends that go here. I love RIT for providing (unintentionally, but still providing) a means by which I can learn to accept myself.
So to answer the original question, yes, there are people here that grew up "hearing", either actually or seemingly. I'm one of them. I don't feel limited by my being hh. If I wear my hearing aid I can understand speech pretty well. If I don't, well, that's OK too because a lot of the people I converse with can sign.
Thanks
