The technique is called binaural sound.  The recordings are made by
placing small microphones inside a dummy head near the eardrums'
location.  They can be quite amazing.  NPR broadcast a radio drama
one or two Haloweens ago which used the technique.  The trouble is, it
sounds quite strange through speakers, mainly due to the odd frequency
balance.
