Years ago when dummy head recording was popular I attended a demonstration

to be perfectly honest the standard two omnis spaced apart the same sort
of distance as ears and separated by a disc approximating to a cross
sectional of a head worked as well as anything.

Did you also hear the Sennheiser record with one side in English and
the other in German?

Interestingly, for me the effect of the German side was much less than
for the English side - probably because the spoken hints were no
longer present. (I did not speak any German at that time.) The power
of the mind to affect perception never ceases to amaze me. ;-)
