It is not so much imitating as creating ILDs and ITDs. Shoulder reflections 
matter dynamically. But they vary from day to day. From the clothes we wear 
etc. I will order four small pairs of headphones today and 3-d print the over 
the ear structures. OSSIC talks about an anechoic rear chamber. I am thinking 
of an open backed structure (which will put your own shoulders into the 
picture!)

Umashankar - so you'd imitate ILDs and ITDs ? From what Ive read shoulder
reflections play an important role as well as the shape of the head - so Im
not sure if Pinna reflections would be enough ?
