dc.description.abstract The ability of human listeners to segregate two sound sources was examined by conducting an experiment when the sources are concurrently presented from different directions in the median plane. A high-pass filtered pink noise was utilized as a sound stimulus in a free-field condition and presented as either a pair of incoherent sound sources or a single-source. Subjects responded whether they perceived sound from one or two directions. Listening tests were conducted with different directions and separation angles of sound sources. These tests consisted of two sessions: a monaural session when only the right ear was made audible, and a binaural session when both ears were audible. The results indicated that the percentage of responding "two directions" for pairwise stimuli exceeded 50% above 33.75 deg. separation angle and reached above 70% at 67.5 deg. separation for both sessions. However, the perceived separation showed weak correlation to the degree of separation although it increased in the binaural session. The ability to discriminate pairwise stimuli to each of two corresponding sound sources showed high statistical significance. The difference between a monaural hearing and binaural hearing was not statistically significant for the segregation of sound sources in the median plane. en
