I have about 60% hearing loss as a result of chronic otitis media as a child. I've learned to deal with it without the assistance of a hearing aid, but I often have to ask people to repeat themselves, which gets kind of embarassing/annoying, etc. But anyways... After a while working with music, you'll become somewhat adjusted. For example, have you ever noticed that when you're in a noisy car or something for a long period of time, eventually you can't really hear the car anymore, but when the car finally stops, your hearing sounds kinda weird? That's your brain adjusting to the environmental sound. It also does this internally (though it can't really make up for signals that are completely lost). In any case, I suggest listening to songs that sound 'good' to other people, professionally mixed and mastered songs (top 40 crud) and using them as a reference for EQ and mastering. It's not a fix all, but it will definitely help in the long run. Also, I suggest you see a doctor. Some hearing loss can be fixed through various methods (surgery, tubes, etc) depending on what caused it. Hope this helps.
