Binaural hearing enables sound-source direction perception that one ear cannot produce

Evidence

Using both ears, we are able to acquire a sensation of the direction from which a sound comes. This can be done even when we close our eyes, or do not see the sound source. Using only one ear, such a sensation cannot be readily produced. This means that we are able to process and correlate the sounds coming to each ear. As always in psychophysics, we have to discriminate between the stimulus and the sensation. Stimulus would be the direction in which the sound source is actually located. The correlated sensation is that of the perceived direction of the sound. The two directions are not necessarily identical. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
