OK, I can't get the formatting right. I was going to explain underneath the chart, but Blogger is not cooperating. Basically, hearing loss is "graded" on decibels. Normal hearing is 0-25 dB in adults. Mild loss is 25-40, moderate is 45-60, severe is 60-85, profound is 90+. As you can tell, my baseline (natural hearing) is nowhere near normal or even mild loss at any frequency(pitch). Once hearing loss reaches a certain decibel level, hearing aids are not very effective. My right ear (not implanted ear) is able to be corrected with a hearing aid. It is not in the normal ranges at all, but it allows me to function. My left ear, as you can see, was not able to be corrected by hearing aids. If you aren't familiar with hearing loss, the top 4 lines probably won't mean much to you, but look at the bottom two. Amazing, isn't it?
