STUDIES TO ASSIST IN NEW KNOWLEDGE

I would love to see a study completed which gathers the hearing thresholds of those who have diagnosed dyslexia, CAPD/APD, and ADD/ADHD.  


Typically when these types of studies are performed the examiners break the hearing thresholds down into classifications of 'minimal', 'mild', 'moderate', etc. In order to allow for optimal analysis, the threshold must be in the raw numeric form rather than broadly classified as normal, minimal, mild; I suspect the impairment would fall in the upper limits of what we currently classify as normal (0-15dB).  The numeric form would allow an easier analysis of a trend as applications of graphs could be used and likely help define a more appropriate and lower threshold value of what a true hearing impairment is.  Would we find that there is, in fact, a lesser value that should be classified as hearing impaired?
