Lateralization is one-dimensional while localization spans three dimensions

Evidence

Effects of lateralization are mostly studied by presenting sounds through headphones. In this case, the sound image is usually located within the head. In such a situation, the task of the subject is to describe the perceived lateral displacement of the sound. This displacement can be projected onto a straight line, which connects the entrances to both ear canals. In contrast to localization, a three-dimensional phenomenon, lateralization is described along only one dimension. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 1708

In contrast to lateralization, which represents a one-dimensional phenomenon, localization encompasses three dimensions. With localization, two effects are important: localization as such, i.e. the perception of a sound with respect to its direction and distance, and localization blur, i.e. the precision by which the location of a sound image can be given. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 1717
