Hearing Eval.

So Andrew had his hearing evaluated last week. The technician said he was with in normal range for hearing. A few days later I got the report and I had no idea how to read the graphs and all the numbers that were on the form. So I showed his speech therapist. She said that normal hearing is in the  -10 to 20, Andrew cam in right at 20 with at 4000 hertz he came in at 25. So depending on who you ask what web site you look at he is either just fine or has mild hearing loss to the higher pitched sounds.  So, yes he is with in normal range on hearing but one more step down he will be considered mild hearing loss.
