I would say that the spcial recognition, as someone said earlier, would be similar to that of animal whiskers to say the least. The way Au Ra hear with their horns is how they pick up and feel air vibrations in the air, since thats what sound is anyways. Which makes it easy to say that they can also feel differences in pressure and movement in the air as well. So it is possible to say that they can sense movement around them albiet not at a long distance but things close to them. They could probably also pin-point the location of a sound without much effort and where its coming from whereas the other races will have to readjust their orientation to do so. Thats how I see it anyways.
