While not addressing such large distances, this study should give some direction on the issues and several comparative studies: M. Rébillat, X. Boutillon, E. Corteel, and B. F. G.

Percept., vol. 9, pp. 19:1–19:17, Oct. 2012, doi:10.1145/2355598.2355602.

I'm looking for a study that measures the effect of linear distance on azimuthal localization error in humans, but am having a hard time finding ones that deal with far field sources (potentially as far as ~200m) and open spaces. Does anyone know of any relevant studies? Thanks! Aurora |
