I think there's every reason to hypothesis that our auditory spatial perception is tied to gravity, and that it is not "audio-only" - that is, our cognitive representation of the space around us is intrinsically multimodal. So, whilst out "up-down" is referenced to gravity, whereas our left-right/front-back is body-referenced. Dr Peter Lennox

Laying on by bed with my feet facing a radio on a bedside table, I certainly perceived it in the correct direction. But there was no sensation as it being 'below' me. What this possibly means is that our perception of direction is not simply relative to our body or head - rather it becomes part of the mental reconstruction of the space around us. And with my brain knowing that I was laying in horizontal attitude it had no reason to create any sensation of a sound 'below' me. It would be an interesting experiment on the ISS: let a blindfolded astronaut float, turn him/her around a few times so all sense of up/down is lost, and then test his/her perception of sounds in all directions. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
