Time-intensity trades revisited

Two experiments were accomplished which involved time-intensity trades on a lateralization task. In the first experiment, subjects adjusted interaural time differences between binaural stimuli to compensate for interaural intensity disparities. In the second, the same listeners adjusted the interaural intensity relationship to offset interaural time differences. Three pure tones (250, 500, and 1000 Hz) were employed as binaural stimuli. The two experiments yielded substantially different time-intensity trading ratios for large values of interaural time differences and intensity disparities. This finding supplies evidence of a new type that the time-intensity trading ratio does not accurately reflect the central auditory processes that are involved with interaural time and intensity on a lateralization task.
