Figure 3From: The contribution of high frequencies to human brain activity underlying horizontal localization of natural spatial soundsDirection discrimination accuracy. The subjects' grand-average accuracy in discrimination of the sound source direction. Stimuli with four different bandwidths were presented from five frontal horizontal directions. Stimuli with the narrowest bandwidth were poorly localized, particularly if originating from the oblique direction angels (-45°, 45°). Error bars indicate SEM.Back to article page
