> LindaAs more and more research is looking at "what is a normal loudness 
contour", the more it is apparent that it is not "that abnormal" for a 
some normal hearing individuals to have what we would consider to be an 
abnormally low tolerance for loud sounds. It may be frequency 
related...that would account for relatively normal UCL's for speech 
under headphones. With IHAFF protocols calling for accurate loudness 
scaling tools, you might try a modified approach to this idea, scaled 
down for this child's age. Seewald (DSL techniques for children) may be 
good resource for the info you are seeking. Just remember that the 
audiogram is a poor and relatively gross measure of how we "hear"!

Good Luck
