| I've read, and have had demonstrated to me, that sounds along the vertical
plane are distinguished by clues other than sound. In other words, when
sound is the only clue, you can only tell left and right, not up, down,
front or back.
A friend with a little beeper won $5 proving this to me. One test, when he
convinced me that the beeper was in front of me, I clearly 'heard' that it
was in front of me, when in fact it was above me.
