Fons can you do 2 experiments? Get someone else than the listener to do random panning to a number of discrete locations. Case A : Sine wave of 50 Hz, linear rise to full amplitude in 150 ms, hold 250 ms, linear fade out of 150 ms. Case B : Use a steady state 50 Hz signal and slowly pan it to new locations.
A table or graf showing the success of locating the virtual sources is what I want :-).

Sine wave of 50 Hz, linear rise to full amplitude in 150 ms, hold 250 ms, linear fade out of 150 ms. The spectrum of such a signal is more than 60 dB down at 100 Hz re. its peak at 50 Hz. Panned to random directions in 3rd order Ambisonics and reproduced on the horizontal octagon at the LABEL studio (Quested SR8). I can *easily* tell from which direction it comes. There is some front/back ambiguity if (and only if) I keep my head fixed, but that is to be expected.
