In the most recent issue of the Journal of the Acoustical Society of 
America, there is an article by Michael R. Stinson in which he describes
the process (mathematics) they used to derive the area function of the
human ear canal.  Assuming that there is an axis defining the centerline
ls the ear canal, they used digitized cross sections taken in normal 
cylindrical coordinates (real world coordinates) and transformed them
to the local coordinates which are cross sections perpendicular to the
ear canal axis.  I believe the issue is June 1989. The authors are Stinson
and Lawton.
