the AAO formula is the .5, 1,2,3 pure tone average minus 25 X 1.5%.
although seldom used by audiologists , it can be useful to know the origin
of the % hearing loss statement. The V.A. system uses a different formula
to determine its compensation rate for hearing loss, that is also
expressed as a percentage, but takes speech discrim. scores into account.
