You said that 40% isn't all that bad, but that you have a hard time hearing people when they talk fast...I would say that since its in the cochlea (where the cilia is located) taht you would have trouble hearing high frequencies, but since it's congenital (appearing at birth) then it may be all frequencies. If you want me to go into detail about what the cilia do, I can (it's going to be an essay question on my Audiology test on Tuesday, so I better know it! lol)...but won't go into that unless you (or someone else) ask for it!

What's amazing is all the advances in hearing aids and other types of amplification that occurs all the time! So I'm sure that you'll have something you want sometime...and maybe sometime soon.
I take it you have analog hearing aids and not digital. I hear those (digital) are a lot more expensive, but are a TON clearer. This is all so interesting, but I have got to get off...I think I've been at the computer doing different things for about 4 hours now! Oops...
