Anyone any ideas how one could provide an audio horizon that could be a

A vague thought, that applies only to a small amount of surround sound
recordings.
I do mostly nature recordings and record also in urban areas, where the
distant
traffic hum is always present. The hum can be heard as a horizontal
noise somewhere
in the distance. Here in the north the distant traffic noise is also
different in the
winter and in the summer. We use studded tyres in the cars and they
cause more
high frequencies in the noise than unstudded tyres. Another thing that
changes the
sound scene in the winter is snow, it makes the general acoustics more
dry and then
it is easier to detect the direction of single sound sources.
The problem is that a constant wide spectrum noise (the traffic hum) is
more difficult
to localize than signals that have transient content.
Having said that, we _do_ localize an above flying jetplane, although it
produces a noise
type sound. We know from experience, that an aeroplane almost always is
flying above us.
But are we actively aware of the fact, that distant traffic hum appears
as a zone above
the horizon?
Also, it would be somewhat strange to put artificially some kind of
signal "beacons"
at the horizon level around the listener, because they aren't part of
the actual recording.
