I'd suggest looking at some of Leslie Kay's work with the Sonicguide. It is a pitch based device (at least for distance) and unlike other readily available etas (electronic travel aids) for the blind he indicates distance with a higher pitch whereas most people indicate it with a lower pitch. He has quite a research base for the way he has developed his system which is now called Kaspa and some research on the pitch relationships.
