I said that I have met during the three decades or so, students who perceive
a stereo image reproduced by two loudpeakers in different ways.
Most people seem to integrate a stereo sound image with a 60 degrees
speaker angle.
They localize a center phantom image, phantom images along the line
between the
speakers, and they hear the surrounding ambience beyond the speakers in
recordings
that have large phase differences. They can localize instruments in
different distances
in the image.
There are also people, who say that they just hear sound from "two
cabinets". They
cannot even localize a center phantom image. They cannot hear a center
phantom
image moving sideways if they move from the center line. It was
difficult to demo
decoded UHJ into four speakers to these people, as they just heard FOUR
speakers!
Then there is a group of people between these. They kinda are able to
localize
phantom images between the speakers.
The thing continues in binaural audio. People localize in very different
ways. I never
localize anything in front of me with binaural. All other directions
work well.
Further on; I have met people, who don't think that there is anything
wrong with a 180 degrees phase difference between the channels, even
with headphones. They are
happy to listen to that. For me it is intolerable, I need to put hands
on my ears or cut
the music right away. 180 degrees phase difference could be used for
torturing me. :-)
I haven't studied this anything deeper. I just have a feeling that
different people
perceive phase and time differences in their hearing system in different
ways.
Why would directional hearing be a different thing in perception than seeing
colours or detecting different smells?
If 90 degrees between the speakers works for you, fine. Most likely the
commercial
recordings you are listening to, have been monitored with an 60 degrees
angle, as
that has been the "standard" setup in studios for more than 60 years. It
didn't happen
when 5.1 came up. On the contrary, the working group that defined the
5.1 setup,
started from a center channel and a good stereo image in front that
works for most
people.
As Dave Malham says, there must be AES papers where this 60 degrees has
been taken
from.
