The real idea of stereo is not to put "signals into your ears" but
rather to
reconstruct sound fields in your listening room.
Well there you are just plain wrong. I strongly suggest you read up
on some of the literature on the subject written by to folks who
actually invented and developed stereo recording and playback.

"In December of 1931, Blumlein patented a remarkable new system of
recording that he called “binaural sound.” Binaural sound was similar
to what we would call “stereo” today. It used two microphones,
recorded two separate recordings, and reproduced them from two
separate loudspeakers. It was intended to duplicate the way we hear
sounds through our two separate ears."
The Bell Labs folks, William Snow, Harry Olson, Keller, Steinberg, knew that
the stereophonic system was a field- type system, not a head-related system,
in which the live sounds are recorded with any number of microphones and
then reproduced on loudspeakers in a similar geometric arrangement to the
microphones. You can develop the entire system, from microphones to number
of channels to loudspeakers and their placement in the room, without any
knowledge of or reference to the human hearing system.
If you duplicate the SOUND of a live event in another space, your job is
done, and you can listen to the result the same way you do to the live
sound, with your natural hearing, no matter your ear spacing, pinnae, head
shape, freq response of your hearing, or anyth;ing else to do with how you
hear. If we could just examine the problem from that standpoint we might
have more success in refining the system and making it sound more realistic.
I guess that answers the tree falling in the forest question once and for
all....
