Yes it is Blauert who proposed the directional bands. They are basically 8kHz for overhead, 4k for front, and 1k for behind localisation, regardless of speaker position, according to Blauert's original paper. He used 1/3 octave band noises. We extended his experiment with more variables of bandwidth, speaker position and the temporal characterstics of source (transient vs continuous), and found Blauert's findings are valid for 1/3 but not necessarily for other variables. Below are Blauert's and our papers.

Its also not applicable to this project which does not use headphones and I do not have time to explain now. Anyone know the answer ? I think it was Bluert ?
