Echolocation Reconsidered: Using Spatial Variations in the Ambient Sound Field To Guide Locomotion.
Ashmead, Daniel H.; Wall, Robert S.; Eaton, Susan B.; Ebinger, Kiara A.; Snook-Hill, Mary-Maureen; And Others
Journal of Visual Impairment & Blindness, v92 n9 p615-32 Sep 1998
Presents an acoustical model and evidence from four experiments that children with visual impairments use the buildup of low-frequency sound along walls to guide locomotion. The model differs from the concept of echolocation by emphasizing sound that is ambient, rather than self-produced, and of low frequency. (Author/CR)
