Human Echolocation - Spatial Resolution and Signal Properties

Norman, L.; Thaler, L.

Abstract

This paper will focus on the echolocation abilities of humans, describing the acoustic properties of their emissions as well as the acuity with which they are able to discriminate certain object properties - distance, angle (horizontal and vertical), size, shape and material - and the various cues that they might use to do this. Chapter Contents: 10.1 Introduction and background 10.2 Acoustic properties of human sonar emissions 10.3 Environmental factors 10.4 Localising objects in space 10.4.1 Localising objects in depth (ranging): signal properties 10.4.2 Localising objects in depth (ranging): spatial resolution of human echolocators 10.4.3 Localising objects in the horizontal plane (azimuth): signal properties 10.4.4 Localising objects in the horizontal plane: spatial resolution of human echolocators 10.4.5 Localising objects in the vertical plane (elevation) 10.5 Discriminating object size, shape and material 10.6 Concluding comments and future directions References
