Sound Localization by Human Observers Symposium Proceedings Held in National Academy of Sciences on 14-16 October 1988
Abstract
The relation between binaural perception of actual sounds in space and of stimuli presented over headphones, base on head-related transfer functions, showed a high correlation. Listeners reported that the sound image presented over headphones remained internal to the head and not external in space, as with natural sound. Head movement, context, bias, experience, and integration of information across senses remain probable contributions to externalizing headphone-delivered sounds at their real-world positions. Sensory information provided by one sense modality may modulate that received by another modality via motor and/or efferent control. Interest was expressed in the possibility of constructing, and adapting to, super localization systems. The symposium focused on mammalian research but crucial insights were reported on other animal models. Thus there was demonstration that auditory space for the cat may be coded by spatial maps within the superior colliclus. Some human data were presented on the poorer accuracy of locating a source in the presence of multiple sources. Monaural localization, and the coding of sound movement were discussed.
