My audiogram for my right ear is worse than that. 65 db loss from 2-8K hz. Straight accross. Probably higher, but that's a standard test.
Given that your hearing loss is pretty consistent across all frequencies, where do you hear your T (i.e. what frequency is it)? Before my surgery, my low frequency hearing was a bit worse than it is now (in my audiogram), but high frequency hearing was much better. So I had some mid range T that could be easily masked. But now its higher pitched and impossible to mask.
