The ultimate goal of sonification is to transfer information effectively to listeners. While there is a large amount of multidisci- plinary investigation in the field of psychoacoustic, psychology, cognition and human computer interaction, sonification design still lacks empirical evidence on which to base design decisions 11],This paper presents an empirical investigation of spatialization, which can provide one or more dimensions for auditory display, It focuses, in particular, on evaluating spatial presentation in soni- fication so as to enhance pattern identification when two audio streams are played simultaneously, Hence it aims to develop de- sign decisions that benefit from effective information representation. The sounds were created for binaural reproduction using non- individual head-related transfer functions. The results reported are based on the listeners' performance within two display modes: (i) two co-located streams and (ii) two streams spatially separated at static locations. It concludes with ideas for future improvements and developments for this type of sonification.
