The results of experiments examining the localized direction of a tone in the presence of band limited pink noise (300-8,000 Hz) are described. Both real and virtual sound images have been considered. It has been found that for signal frequencies of approximately 1 kHz or less the perceived image position is shifted away from the noise source regardless of image type. For higher signal frequencies, the sound localization for a tone was markedly disrupted by the presence of interfering noise. The shift of localized direction of a signal away from the noise may be explained as being due to a kind of spatial masking between them. This would cause a deformation of the sound image of the signal which in turn results in the biasing of a ‘perceived center’ of the signal sound image away from the noise.
