LOCALIZATION ACCURACY RESULTING FROM ISOLATED BINAURAL STIMULATION

Abstract

Judgments of the apparent azimuth of 5 different types of sound stimuli (pure tone, sustained vowel, continuous speech, music, and white noise), given in six 5-sec presentations each over a dual-channel stereo-phonic system, were made by 205 subjects. The microphones e=were mounted on a turntable which rotated through 360 deg and separated to simulate intra-aural distance. The subjects were unable to localize the 5 sound types within a full quandrant of + or - 45 deg, but music was localized within a quandrant better than chance. There were significant differences between localization frequency when the correct criterion was + or - 90 deg. Sixteen per cent of all responses were 18 deg away from the stimulus sounds.
