I. Time versus Intensity in the Localization of Tones. II. Lateralization versus Localization.

摘要

I. Subjects were asked to match the lateral position of one tone, the signal, by means of another, the pointer. The two tones were presented alternately. The experimenter selected a combination of interaural time and intensity differences for the signal, and the subject adjusted the interaural time difference for the pointer until it seemed to him to be in the same lateral position as the signal. Subjects having normal hearing perceived the signal in two places, one strongly affected by the difference of level at the two ears, the other almost wholly dependent upon the difference of time. II. The accuracy with which subjects could assign an azimuth position to a sound coming to them over earphones was studied. The subjects did about as well initially as Stevens and Newman's subjects did with an external source, and they showed a small amount of improvement with practice. (Author)
