Sadly this info is not published as far as I know,
I have it from Ingvar Öhman http://lmgtfy.com/?q=ingvar+%C3%B6hman&l=1 who
had a research company for researching how the human hearing work together
with the 2 loudspeaker stereo system.
He did a demo recording showing how you could do stereo with height mixing
For The Swedish Radio (Sveriges Radio) a long time ago with very low
interest from them.
Stereo with height - (reflecting)
This is a truly audiophile approach... ;-)
But I don't want to be too ironic: interesting anyway. And such
techniques could be applied to 5.1 etc., as well. (What the Mpeg seems
to offer as "tool" in the case of Mpeg-H 3DA, BTW. )

P.S.:
I have talked to him about this, He has never been much of a publisher
other than in discussion forums in swedish.
A pity?!
And of course is using it in his business as consultanta and designer,
So I have only the principal description that individual HRTF's over 4kHz
makes things worse for 90% of the population and that is frequency bands
that for the majority of people gives an impression of height when raised
in amplitude.
Must read:
"... that < generic > HRTF's over 4kHz makes things worse for 90% of
the population" ?
We must keep precise, in this context.
