I am not even going to copy the original document we got from the dr because it is just a bunch of squiggly lines. This is the results of Lilli's BAER that tells us what she can and cannot hear. It is color codded left ear, right ear and both ears combined. Notice the flat lines, which means it is SUPER easy to fit her for hearing aids. The flat lines mean that she can hear everything, it just has to be amplified. If they were wavy it would mean her new ears would have to be adjusted to amplify certain sounds and not others and increase pitch/tone of certain sounds. According toall the professionals this is beautiful and heavenly to look at :) The banana in the middle is actually called the speech banana. It is where the sounds of the english language fall. Some sounds are easier to hear then others so Lillian can hear those sounds with out us having to be loud its just to her they sounds like a whisper. The louder we are the better she hears everything. Again, I am now thankful our family is naturally loud. Another thing to note is that since sounds travel in waves it is a much shorter distance from 20-30 decebles than from 50-60 The pictures on the graph is a guide to show what sounds fall in that range. To better illustrate this concept notice the kitten purrs at about 20 decebles and 175 hertz while a large dog (like ours who always wakes her up when he barks) barks at 80decebles and 2000 hertz. The black drawn in line at the top is where her HAs will bring her hearing up to, which is very actually a bit above "typical" hearing. Sorry if this post has been nothing but a boring science lesson for some of you but to us it is so great to be learning all we can to help our tiny as much as possible! :)
