WATCH OUT!!!
"To hear someone on the phone or 'behind you!' is quite different an experience."
That is precisely the problem... Ideally should be no difference. Although it is more logical that you should hear that person talking in front of you. When you are in a completely dark room and relatively close to someone else you can clearly identify where that person lies... behind you or in front of you, to the right or to the left, close to you or far from you. However if you keep your head stright you cannot identify that person's height.
You have raised another interesting aspect of the earing/vision mecanism... If you try to record a bar conversation with a friend and later on hearing it on an audio system (independently of its accuracy) you'll see that it is almost unlistenable... Why? Because when you are at the bar with your friend because of all that noise from other people you'll always try to look at him when he is talking in order to follow his words... your brain is now relying in your vision to assist your ear mecanism and filter out the noise.
