Abstract
A set of three studies was designed to investigate the role of touch-produced sounds in the perception of surface texture. Subjects were capable of judging roughness on the basis of sounds alone. Auditory judgments were similar, but not identical to corresponding haptic touch judgments. When both sources of information were available, subjects tended to use the tactile cues. The nature of the auditory stimulus for roughness is considered.
