The ability of human listeners to segregate two sound sources was examined by conducting an experiment where concurrent noise stimuli were presented from different directions in the median plane. High-pass filtered pink noise was utilised as sound stimuli in an anechoic chamber and presented as either a pair of incoherent sound sources or a single-source. Subjects were tested with both monaural and binaural hearing, and responded whether they perceived sound from one or two directions. The responses showing "two directions" for pairwise stimuli exceeded 50% above 33.75◦ separation and reached above 70% at 67.5◦ in both monaural and binaural hearing sessions. The difference in the ability to segregate sources in the median plane with binaural or monaural hearing was not prominently different.
