I have T but no appreciable hearing loss. That being said, I know (or knew) people that had hearing loss and with hearing aids they functioned well at work. I have even worked with two people that are completely blind and you would not have a clue when you speak with them or communicate by e-mail.
If you are really concerned, see an employment attorney for advice. It shouldn't cost a lot and they can advise you on the best course to take during interview and the ADA.
And hey, if I recall, you have had tinnitus during your last year of college and yet you still graduated! Didn't hold you back getting your degree, so it shouldn't hold you back in performing in your job.
Good luck, and welcome to the Rat Race!
